IGNIS (SIRI) MOD. 4210 SERIE IL MILIONE YEAR 1963.

The IGNIS (SIRI) MOD. 4210 SERIE IL MILIONE is a special edition refrigerator and is another everlasting.

Was called serie  "IL MILIONE" (The million series) because IGNIS (SIRI) manufacturer have surpassed at the time his million produced fridge, and designed this model with this special mark for that reason.

It was produced by SIRI (Società Italiana Refrigeranti Industriali) wich was the BORGHI industrial conglomerate dedicated to refrigerator fabrication in ITALY capable to export his products widely in Europe in the 60's.

The  IGNIS (SIRI) MOD. 4210 SERIE IL MILIONE  after power up  starts cooling in less than 8 seconds
and a nice hiss noise can be heard at freezer level. The compressor with it's 1150 rpm is almost runnin  in absolute quietly silence with a quite powerful pumping feature.

The IGNIS (SIRI) MOD. 4210 SERIE IL MILIONE  is ready to be used after 30mins after startup, even with an external temperature of 35°C !! !! !
and  it has the awesome feature of a pedal to open the door when both hands are occupied. (A foot door opener attachment for a refrigerator for easily and conveniently opening the door of a refrigerator with little effort. The foot door opener attachment for a refrigerator includes a mounting bracket being adapted to securely attach to a side wall of the refrigerator near where the door to the refrigerator can be opened; and also includes a spring-loaded lever being pivotally mounted at a central portion thereof to the mounting bracket and having a second end, a first end, and a spring member being securely attached to the mounting bracket and to the first end to bias the first end of the spring-loaded lever out of contact with the door of the refrigerator; and further includes a foot support member being securely mounted to the second end of the spring-loaded lever; and also includes a door opening member securely attached to the first end of the spring-loaded lever).

After 50 years it doesn't suffer the "weight" of it's age............................



The refrigerator is running with a STEMPEL HERMETIK HP 1/8 V220 V230 50/60HZ. compressor which was last officially produced STEMPEL HERMETIK before closing and deletion by Danfoss aquisition in 1964. These compressors weren't sharing anything technologically with  TECUMSEH or  others brands related patents therefore are pretty unique.

The compressor and the coil plant in this fridge is a rare example of powerful cooling.....quiet.....reliable evelasting running.

Many contemporary appliances would not have this level of staying power, many would ware out or require major services within just five years or less and of course, there is that perennial bug bear of planned obsolescence where components our deliberately designed to fail or manufactured with limited edition specificities..............................

The present invention relates TO refrigerating machines.

More particularly, the present invention relates to the
motor compressor unit of a refrigerating machine and
especially to the carrier which is connected to the motor
and the compressor of such a refrigerating machine.

Such a carrier is conventionally made from a material
such as cast iron which must be machined considerably
after it is cast. Furthermore, such a carrier member
must be perfectly clean before it is incorporated into the
to refrigerating final assembly in order to guarantee proper operation,
and the machining of a cast member creates great prob-
lems in cleaning the member after it is machined because
chips, oil and the like, get into inaccessible places. In
addition, a motor compressor unit of a refrigerating
machine is required to be located in an extremely small
space, and the minimum size required by a carrier in
the form of a casting often creates difliculties with respect
to the small space afforded for the motor compressor
assembly. It is apparent, therefore, that in a conven-
tional motor compressor assembly the provision of a
conventional carrier which is a cast member machined
subsequent to its casting creates many difficulties and un-
desirably increases the cost of the structure.

It is an object of the present invention to overcome
the above drawbacks by providing for a motor compressor
assembly of the above type a carrier which is not made
from a cast member and which need not be machined.
In this way, many of the above-mentioned problems re-
sulting from the machining and the cleaning of a cast
member are avoided.

It is a further object of the present invention to form
a carrier of the above type oL1t of sheet metal which
may be stamped to a desired configuration and which
may be formed with suitable openings and the like simul-
taneously With the stamping, so that the inconveniences
produced by the above-mentioned machining are com-
pletely avoided.

Furthermore, it is an object of the present invention
to provide in sheet metal“ members of the above type
bulged portions which are capable of providing the carrier
 with chambers for reducing noise and for conveying
the refrigerating fluid along a desired path between
the compressor on the one hand and a condenser and
evaporator on the other hand.
Still another object of the present invention is to pro-
vide a process for forming a carrier of the above type
which eliminates many of the steps required in a conven-
tional process for forming a carrier.

Furthermore, it is an object of the present invention
to provide a structure capable of accomplishing all of
the above objects and at the same time being composed
of simple, rugged elements which are more reliable in
operation, which are inexpensive and simple to manu-
facture, and which are very easily assembled together.

With the above objects in view, the present invention
mainly consists of a carrier for the motor compressor
of a hermetically sealed refrigerating machine, this carrier including at least two sheet metal members at least
partly overlapping and joined fluid-tightly to each other
and formed with openings and bulging portions serving
as connecting surfaces, noise-reducing chambers, and a
bearing carrier.

Also, with the above objects in view, the present in-
vention mainly consists of a process for forming a carrier
of the above type, this process comprising the steps
of stamping into at least one of a pair of sheet metal
plates a plurality of depressions and openings, and soldering these sheet metal plates together in an inert
atmosphere to provide a fluid-tight connection between the
plates.

The novel features which are considered as charac-
teristic for the invention are set forth in particular in
the appended claims. The invention itself, however,
both as to its construction -and its method of operation,
together with additional objects and advantage thereof,
will be best understood from the following description

Fig. 13 is a schematic, overall view of the refrigerator
unit, showing the pipe connections between the motor

Referring now to the Figs. 1-3, it will be seen that the
carrier illustrated in these figures includes an outer dished
member 1 and an inner dished member 2 nested within
the outer dished member 1 and joined together in a fluid-
tight manner preferably by soldering in an inert atmos-
phere so that the dished members 1 and 2 are unified
into a single unit.
In accordance with the present invention the dished
members 1 and 2 are formed with bulged portions which
define the noise-reducing chambers 3 and 4- when the
dished members 1 and 2 are assembled in the manner
illustrated in Figs. 1-3. Furthermore, the dished mem-
bers 1 and 2 have bulged portions which together define
antechambers 5 and 6 adapted to communicate with the
compressor and respectively communicating with the
chambers 3 and 4 through the conduit portions 7 and

3, respectively formed by elongated bulges in the outer ‘I

dished member 1. These dished members are formed
with additional bulged portions 9 which are adapted to
be connected to springs 10 in the manner shown in Fig.
2, these springs resiliently supporting the motor compressor assembly, best shown in Figs. 10 and 11, and it
will be noted that all of these bulged portions are sym-
metrically distributed in the floors of the dished mem-
bers 1 and 2. The dished member 1 is furthermore
formed with lateral, outwardly bulging portions 11 serv-
ing to fasten the dished members to the stator 12 of an
electric motor. Preferably, bored blocks M are located
within the spaces 13 formed between the bulged portions
11 of outer dished member 1 and the outer surface of
inner dished member 2, and these blocks 14 are soldered
to the dished members and serve to guide the connecting
members 15 which serve to connect the carrier to the
motor. Furthermore, the bottom wall portions of the
dished members 1 and 2 are formed during stamping of
these dished members, for example, with substantially
frusto-conical extensions 16 and 17, respectively, which
are centrally located with respect to the dished members
and which extend away from each other in the manner
indicated in Figs. 1-3. These tubular extensions 16 and
17 serve as a support for a bearing sleeve 18 (Fig. 1)
which serves as a bearing for the crank shaft of the com-
pressor, this crank shaft being driven by the motor 12
as shown in Figs. 10 and 11. This bearing sleeve 18 is
welded firmly to the extensions 16 and 17 so that in ad-
dition to serving as a bearing, the sleeve 18 serves the
additional function of adding stiffness to the assembly
which forms the carrier of the present invention.
Where the carrier of the invention is to be used with
a hermetically sealed motor compressor assembly of high
output, such as for large refrigerators or refrigerated
show cases, then, of course, the noise-reducing chambers
3 and 4 as well as the antechambers 5 and 6 must be
fairly large. In order to be able to form chambers 3-6
of the required size in a practical manner, the bulged
portions of the dished members 1 and 2 which define
these chambers are mirror images of each other so that
each member 1 and 2 is required to provide only a frac-
tion of the volume of these chambers, and in this way
it is possible to provide the desired large volume of these
chambers without difficulty. On the other hand, the
smaller conduit portions 7 and 8 as well as the suction
conduit portion 19 leading to the chamber 3 are formed
only in the dished member 1 by stamping the elongated
bulged portions therein indicated in the drawings.

 Openings 20-23 are preferably formed by stamping
simultaneously with the stamping of the dished mem-
bers or if these dished members are drawn then the
openings 2tl——23 may be stamped immediately after the
drawing in a combined drawing and stamping machine.
The opening 23 serves as a connection for a looped pres-
sure conduit which extends from the opening 235 the casing wall of the refrigerating machine through the
sealed cooling medium to the condenser, while the re-
frigerating medium flowing back from the evaporator of
the refrigerating machine flows along the suction con-
duit 19 to the suction side of the compressor as diagram-
matically shown in Fig. 13. In other words, the suc-
tion inlet of the compressor communicates with the open-
ing 21 to draw fluid through conduit 19 into chambers
3 and from the latter through the conduit 8 into the
antechamber 5 from where the fluid flows into the com-
pressor to be forced by the compressor through the
opening 21 connected to the pressure outlet of the com-
pressor and then along the conduit 8 through the cham-
bers 4 to the opening 23 from where the medium flows
in the manner described above to the condenser.
In order to connect the compressor 4’ to the carrier
1, 2 in a fluid-tight manner, a steel plate 24 (Figs. 2,
10, 11 and 12) is soldered to the outer surfaces of the
antechambers 5 and 6 and the compressor is joined to
this steel plate 24 with a suitable sealing element located
therebetween. The plate 24 is provided with a pair of
elongated cutouts 25 separated by a wall portion of
the plate 24, and these cutouts 25 respectively commu-
nicate with the openings 21 and 22 and with the suction
and pressure sides of the compressor so that in this
way the compressor sucks fluid from chamber 5 and
forces fluid into chamber 6.

The embodiment of the invention which is illustrated
in Fig. 4- and which is suitable for motor compressor
units of lighter weight and smaller output as compared
to that associated with the embodiment of Figs. 1-3,
differs from that of Figs. 1-3 in that the carrier of Fig. 4
includes only one dished member 1a. The other sheet
metal member which cooperates with the dished sheet
metal member 1a to form the carrier of Fig. 4 is simply
in the form of a substantially disc-shaped plate 2a
soldered to the outer surface of the bottom wall of
the dished member 1a. With the embodiment of Fig. 4
only the sheet metal member 2a is formed with the
bulged portions which provide the chambers 3-6 and
the conduit means 7, 8 and 19 communicating with these
chambers. However, the bulged portions 9 which serve
as connections to the springs 10 and the bulged portions
11a which serve to connect the carrier to the motor are
formed in the dished member 1a. Furthermore, the
substantially frusto-conical tubular projections 16 and
17 are respectively formed in the members 2a and la
and serve in the same way as in the embodiment of
Figs. 1-3 to carry the bearing sleeve for the crank shaft
of the compressor. With the embodiment of Fig. 4 the
outer diameter of the single dished member 1a may be
made relatively large inasmuch as the bulged portions
Ila are formed by reentrant portions extending inwardly From the outer periphery of the dished member 1a, and with this embodiment, elements such as the blocks 14 shown in Fig. 1 are unnecessary and are omitted. Except for the above differences the embodiment of Fig. 4
is identical with that of Figs. 1-3 and cooperates in the same way with the motor and the compressor of the refrigerating machine.
Figs. 5-8 illustrate an embodiment of the invention
which may advantageously be used with stators which
do not have a cylindrical outer configuration, but which
are, instead, more rectangular and provided with rounded
corners, as they are sometimes formed in the newer re-
frigerating machines in order to save weight and space.
Thus, with this embodiment of the invention, the carrier
includes essentially a four-cornered box 32 open at its
top as shown in Fig. 6 and formed by turning upwardly
and joining to each other the flaps 30a formed in the
plate 34) of Fig. 5 by forming angular cutouts 31 in the
corners of this plate 36, and a substantially fiat plate
33 joined to the outer surface of the bottom wall of the
box 32 and extending at one Sid? beyond the box 32.


The joining of the members 32 and 33 is preferably
formed by spot or roll welding at suitable places. Fur-
thermore, the upwardly bent flaps 30a which abut at
their side edges are welded together at these abutting side
edges. As is apparent from the drawings, the floor
portion of the box 32 as well as the plate 35 are formed
with the substantially frusto-conical tubular aligned ex-
tensions 17 and 16, respectively, which extend away
from each other in the manner shown in the drawings
and which serve to carry the bearing sleeve 18, as in-
dicated in Fig. 8. Furthermore, both the plate St) and
the plate 35 are formed with openings 20, the openings
20 of plate 35 being aligned with the openings 20 of
box 32 when these elements are joined to each other, and
the connecting screws 15 of the stator extend through
these openings when the motor is fixed to the carrier of
Figs. 5-8.

The bulging portions which form the noise-reducing
as well as fluid guiding chambers 3--6 as well as the
conduits communicating with the same are formed in
a separate plate 34 with the embodiment of Figs. 5-8,
this plate 34 being joined directly to the underside of
the plate 35 as by being soldered thereto in a fluid-tight
manner. In the same way as was described above, the
outer surfaces of the antechambers 5 and 6 have a plate
24 fixed thereto in order to properly connect the com-
pressor with these antechambers. After the three parts
32-34 are joined together in the abovedescribed manner,
the portion of parts 33 and 34 which extend beyond
the box 32 in the manner shown at the right of Fig. 8
are bent upwardly to the dot-dash line position indicated
in Fig. 8 so that the conduits 8 formed by elongated
bulges in the plate 34 are curved, and it will be noted
that in this dot-dash line position, which represents the
final form of the structure, the portion 35 of plate 33
which extends beyond the box 32 as well as the portion
of plate 34 joined to portion 35 are located closely ad-
jacent to the box 32 so that the space required for the
assembly is reduced in this way.

A further embodiment of the present invention is illus-
trated in Fig. 9 which is of advantage in that the distance
through which the compressor extends downwardly from
the carrier and radially toward the casing wall is less
than would otherwise be the case, which is of consider-
able significance with respect to the eflective size and
material requirements of the casing, so that with this
embodiment great advantage is derived from the saving
of space required by the casing in the refrigerator. As
is Well known, only a minimum space is provided in a
modern refrigerator to accommodate the refrigerating
machine.

In contrast to the embodiment of Figs. 5-8, the em-
bodiment of Fig. 9 is provided with relatively large
frusto-conical tubular extensions 17a and 16a respectively
formed in the sheet metal plates 32 and 33 which are
joined to each other in a fluid-tight manner, as described
above. These plates 32 and 33 which are, for example,
soldered together, are fixed to the stator 12 in the man-
ner shown in Fig. 9. Because of the relatively large
aligned extensions 16a and 17a which extend away from
each other, these extensions together with the bearing
sleeve 13 carried by the same define a relatively large
chamber ea. Furthermore, the sheet metal member 33
is not spot welded to the dished sheet metal member 32.
instead, these members are soldered together in a fluid-
tight manner and furthermore, an opening 22a is stamped
in the member 33 and is located in a position diamet-

'rically opposed to the tubular extension 40 which is

soldered to the plate 33 in alignment with another open-
ing passing therethrough. Finally, the valve plate 24
of the compressor 41 fragmentarily illustrated in Fig. 9
is soldered in a fluid-tight manner to the plate 33 and
extends as much as possible toward the lower tubular
extension 16a.
In this manner, the distance through which the com-
pressor 41 extends downwardly and laterally from the
carrier 32, 33 of Fig. 9 is substantially shortened which
is principally made possible by the fact that now the
chamber 4a may be used as part of the path for the fluid
under pressure as well as for noise-reducing purposes
and, therefore, this space between the tubular extension
and the bearing sleeve is no longer a dead space which
serves no purpose. The suction noise-reducing chamber
3:: is formed as a separate element with this embodiment
of the invention and communicates through a tube 42
connected to chamber 3a with a suitable bore formed in
the valve plate 24. The suction line communicates with
the chamber 3;; at the opening 43 thereof so that the
sealed gas may flow in the direction shown in the arrows
in Fig. 9 through the pressure noise-reducing chamber
dc: to the outlet opening 23;: of the tubular extension 4-2
to which the pressure line leading to the condenser is
joined.

It will be understood that each of the elements de-
scribed above, or two or more together, may also find a
useful application in other types of refrigerating machines
differing from the types described above.

While the invention has been illustrated and described
as embodied in a carrier for refrigerating machines, it is
not intended to be limited to the details shown, since
various modifications and structural changes may be
made without departing in -any way from the spirit of the
present invention.

Without further analysis, the foregoing will so fully
reveal the gist of the present invention that others can
by applying current knowledge readily adapt it for various
applications without omitting features that, from the stand-
point of prior art, fairly constitute essential characteris-
tics of the generic or specific aspects of this invention
and, therefore, such adaptations should and are intended
to be comprehended within the meaning and range of

IGNIS (SIRI) MOD. 4210 SERIE IL MILIONE  Motor-compressor STEMPEL HERMETIK HP 1/8 V220 V230 50/60HZ.

The present invention relates to motor-compressors.

More particularly, the present invention relates to
motor-compressors of the type which are hermetically
sealed and “used in household refrigerators, for example.

With such motor-compressors it is known to provide
a carrier which is common to the motor as well as the
compressor in order to provide a very compact arrange-
ment. However, the motor-compressors known upto
the present time are expensive to manufacture particu-
larly because of the difficulties in providing the suction
and discharge valves for the cylinder of the compressor.
It is conventional to locate these valves in the end wall
of the cylinder, and this latter arrangement is exceed-
ingly complicated and expensive because of the necessity
for providing in the end wall of the cylinder a chamber
for accommodating both the suction and the- discharge
valves as wellas all of the structure associated ‘with the
suction and discharge valves. . V

One of the objectsiof the present invention is to over-
come the above drawbacks by providing an arrangement
which is far less expensive than the conventional;ar.-
rangement described above.

Another ‘object of the present invention is to provide
an‘ arrangement where only one valve need be accom-
modated at the end Wall of the cylinder of ‘the com-
pressor.

A further objectof the present invention is to pro
vide a motor.-compressor partwhich serves to mount the
cylinder on the carrier of the motor-compressor with a
structure which enables this part to additionally serve
the function of housing a valve of the motor-compressor.

An additional‘ object of the; present invention is to
provide a structure capable of accomplishingall of the
above objects and at the same time being composed of
simple ‘and ruggedly constructed; elements which are in-
expensive to manufacture and assemble and which are
very reliable in operation.
With the above objects in view, the present invention
mainly consists of a motor-compressor which includes a
carrier for carrying both the motor and compressor. A
cylinder forms part of the compressor and is provided
of the cylinder for controlling the flow of fluid therefrom.
The novel features which are considered as character-
istic for the invention are set forth in particular in the
appended claims. The invention itself, however, both as
to its construction and its method of operation, together
with additional objects and advantages thereof, will be
best understood from the following description. of specific

panying drawings, in which:

Referring now to the drawings and to Fig.‘ 1 in par-
ticular, it will be seen that a carrier 18 is provided for
carrying both the motor and the compressor. This car-
rier l8 isjmade of sheet metal and is ‘suitably shaped
as indicated in Fig._ 1 for carrying both the motor ‘and
the compressor. The stator" of the motor is directly
carried by the carrier 18, and at the upper left_ portion
of Fig. 1 is shown‘ the bearing of the motor which turn-
ably guides the motor shaft, this hearing being ‘directly
carried by the carrier 18, as indicated in Fig. _1. “The
motor shaft extends downwardly beyond the bearing
shown at the upper left portion of Fig. 1 in a substan-
tially vertical direction and is connected through a suit-
able crank to a piston which reciprocates i.n the cylinder
1 shown in Fig. 1, this cylinder, 1 ‘forming part'.o_f the
compressor which is also carried, by the carrier 18.
The cylinder 1 is fixed to, the carrier 18 ‘through the
medium of a block 2 which will be further ‘described
below.

The cylinder 1 has an elongated end portion‘ 3 of a.
lesser thickness than the remainder of the cylinder ‘and
joined to the remainder of the cylinder by a shoulder 4.
An end ‘wall 5 together with a sealing disc _6 formfan
end wall means for the cylinder, and this end. wall‘._5,is
' surrounded by the end portion 3 of. the cylinder and.is
with an end portion of a lesser wall thickness than the
remainder of the cylinder and joined to the remainder
of the cylinder by a shoulder in the, interior of the cylin-
der. This end portion of the cylinder accommodates
an end wall which is fixed to the cylinder and formed
with a bore for admitting fluid into the interior of the
cylinder. Between this end wall and? the shoulder of
the cylinder there is clamped, a« sealing ‘disc which is
formed with an elongated cutout in which is located a
valve member for opening and closing the bore of the
end wall ‘of the cylinder. The cylinder is further formed
with a lateral bore which ‘communicates with a bore in
a ‘block which forms part of ‘a mounting means for
mounting the cylinder on the carrier. ‘This mounting
meansincludes a discharge‘ valve structure which com-
municates through a bore of the block with the interior
spaced from the shoulder 4, in the manner indicatedjin
Fig. 1.. The sealing disc 6 is, clamped between the shoul-
der 4 and the end wall 5,‘_and’this clamping is‘brought
about by the free end portion of the cylinder which ex-
tends beyond the end walls and which is rolled over
in the manner indicated in Fig. 1 against the ‘end wall
5 to fix the latter to the cylinder as ‘well has to press
the sealing disc 6 against end wall 5 and the ‘shoulder
This sealing disc 6 may be made of any relatively soft
metal such as lead or tin, or it may be made of a_ -suitable plastic.
The end wall 5 is formed with a substantially“axial-
bore 7 through which fluid to be compressed‘ e‘nters.int_o
the‘ cylinder 1 during the suction strokes of thepiston
which lies therein. 1 At its face which is directedtoward
the interior of the cylinder 1, the end wall _5 is, formed
with an annular recess surrounding the bore 7 and pro-
viding at the inner face of the end wall 5 a valve ‘seat
portions.
The sealing disc 6 is formed, as is shown Almost"'clear
in’Fig. 3, with -an elongated‘ diametr-al cutout 10 which
is‘ of a substantially rectangular configuration and which
has narrow end portions 11, so as to provide the cutout
1_0: withclateral portions 12 which. are wider than the
portions 11. The end portions 11 of ‘the cutout Ill ex-
tend almost upto the periphery of the disc 6 and over-
lap,’ the. shoulder 4, in the manner shown most clearly
in Fig. 3a. .

The valve. member 9 is in the form of an elongated
metal strip, for example, and has a lesser thickness than
the sealing disc 6, as shown in _Fig._ 3a. This valve mem-
ber..9.'overlaps~with its free end portions the shoulder 4,
so that, as indicated in Fig. 3a, the valve member 9 is
freely movable between the shoulder 4 and the end wall
5; within the limits provided by the difference between
the thickness of the sealing disc 6 and the valve member
9. As is indicated in Fig. 1,. the annular channel of the
end. wall" 5 whichforms the valve seat 8 is wider than
the valve member 9, so that the latter is capable of en-
gaging. the valve seat 8 without interference in order
to close the bore 7.

THE opeRAtion. of the above described suction valve
structure for the cylinder 1 is believed to be evident.
‘Whenever. the piston in the cylinder 1 performs a suc-
tion stroke it willfautomatically draw the valve member
9.. away from the plate 5 to. open the bore 7, while .dur-
ing the pressure. strolzesof the piston the valve member
9 will be urged automatically into engagement with the
valve seat 8 in order to close the bore 7.

The block 2 which serves to connect the cylinder 1 of
the compressor to the carrier 18 is formed with a ‘bore
13,’and a lateral wall portion of cylinder .1 is formed with
a.bo1'.e which forms an extensionof the bore 13 and
which. is tangential to the shoulder 4 and the disc 6,
asisindicated in Fig. 1.. These latter bores form the
discharge bore. throughwwhich-fluid‘ under pressure is
discharged.fROm..the.interior..of thecylinder .1 during the
compression strokes of the pistontherein.

A channel means.22a is fixed to.the carrier .18 in the
manner indicated in Fig. llto form therewith a pressure
chamber .22 which also serves as .a noise reducing cham-
hen. This. pressure chamber 22 communicates with a
discharge conduit 25. The channel means 22a includes
apart opposite ‘a wall portion .of the carrier.18 and
formed with oneof a pair of openings 21 communicat-
ing with. the interior of the pressure chamber 22.

c A wall. member 23a is fixed to the channel means 22a
at its exterior wall and is also formed with an opening
Zlcommunioating with the opening 21 of the channel
means 22a. Four side walls 23 are fixed to and extend
fromthe -wall 23a to form therewith a substantially box-
shaped structure which. serves as a discharge valve cham-
ber... A sealing ring 21: engages the free edges of the
walls» 23, and the block 2 engages the sealing ring 2a.
As..is, indicated in Figs. 2 and 2a the block 2 is formed
witha pair of openings 19 through which a bolt extends
into threaded engagement with a pair of the walls 23 in
order to fix the block 2 to the walls 23, and in this way
fix the cylinder 1 to the carrier 18, the ‘cylinder 1 being
‘directly fixed to the block 2. The. channel means 22a
may be soldered or welded to the carrier 18, and the wall
23a may be soldered or welded to the channel means 22a,
while the four walls 23 also may be soldered or welded
to the wall 23a. Thus, it will be seen that the block 2
together with the walls 23a.and 23 form a valve cham-
ber 20 in which a discharge valve means is accom-
modated.

The. face 14 of the block 2 which.is.‘directed toward
the. interior. of the enclosure 20 and away from the cyl-
inder .1 is polished and is.formed with an annular recess
surrounding the bore 13 and providing at the interior of
the enclosure 20 a valve seat 15. An elongated. valve
member 16 having awidthwhioh is less than the outer
diameter of the annular recess defining the valve seat 15
iswadapted to engage the -valve seat 15 for closing the
bore 13 and to move’ away from the valve seat 15 for
opening the bore. The structure of the discharge valve
means isshown most clearly in Figs. 4 and 5.

Thus, referring to Figs. 4 and 5 it will be seen that the
block 2 has a pair of pins 17:: fixed to and extending
therefrom into the interior of the enclosure 20. These
pins extend through a valve stop member 16a and into
a pair of coil springs 17 in order. to guide the latter.
Thus, the springs 17 urge the valve stop member 16::
toward the block 2, this valve stop member 16a being
formed with bores through which the pins 17a freely
extend. As is indicated in Fig. 4 the central portion of
the valve stop member 16a is curved away from the block
2 and has a concave face directed toward the same.
The valve member 16 is located between the stop
member 16a and the block~2, and thistvalve member 16
is formed at its ends portions with a pair of notches
through which the pins 17a freely extend, as clearly indi-
cated in ‘Fig. 5. Thus, the springs 17 act through the
member 16a to urge the" valve 16 to its closed position,
where the valve 16 engages the valve seat 15. However,
when fluid under pressure is urged through the bore 13
from the cylinder 1 during the pressure strokes of the
piston therein, the fluid under pressure is capable of mov-
ing thevalve member 16 away from the valve seat 15
into engagement with the central curved portion of the
valve stop member 16a, and at’ this-time the fluid under
pressure can flow freely into the enclosure 20 and through
the openings 21’ into the pressure chamber 22 and from
the latter through the discharge conduit 25. During. the
suction strokes of the piston in the ‘cylinder 1, the valve
member 16 automatically .moves back to ‘its.position-en-
gaging the valve seat 15 for closing the bore 13. Thus‘,
the structure whichserves to mount. -the cylinder '1 on
the carrier 18 also serves to accommodate the discharge
valve structure which cooperates withithe compressor.

A suction. chamber 24 which also serves as -anoise re-
ducing chamber is provided,- in’ the ‘manner’ shown’ in
Fig. 1, with a wall portion having ‘a tubular extension 7a
drawn therefrom, and this tubular extension 7a extends
with a press fit intothe bore —7 of the end wall 5, so that
in this exceedingly simple manner the suction chamber
24 is fixed directly to the end walL
Thus, it will be seen that with the above described
structure of the invention the end wall ‘assembly of- the
cylinder is exceedingly simple,’ and the structure for
mounting the cylinder on the carrier 18 also serves to
‘accommodate the discharge valve structure for the cylin-
der. Thus, the cost of the assembly‘ is greatly reduced.
The unillustrated parts of the motor compressor are con-
ventional and well known to those skilled in the art.
It will be understood thateach of the elements de-
scribed above, or two or more together, may ‘also find
a useful application in other types of motor-compressors
difiesring from the types described above. .
‘While the invention has.been illustrated and described
as embodied in motor-compressors for household‘ re-
frigerators and the-like, it is not intended to be limited to
the details shown, since various modifications and struc-
tural changes may be made without departing in any way
from the spirit of the present invention.

Without further ‘analysis, the foregoing will so fully
reveal the gist‘ of the present invention that others can by
applying current knowledge readily adapt it for various
applications without ‘omitting features that, from’ the
standpoint of prior art, fairly constitute essential char-
acteristics of the generic or‘ specific aspects of thisinven-
tion and, therefore, such adaptations should and are in-
tended to be comprehended within the meaning and range

 IGNIS, GIOVANNI BORGHI HISTORY.

 Investing in the industrial development of artisan villages
in Varese, Italy, Giovanni Borghi builds a factory for 200
employees to manufacture not only ovens and cooktops, but
also an appliance previously unknown in Italy: the refrigerator.
Ignis workers produce appliances for third-party companies
like Fiat, Atlantic, Philco, Emerson and Philips. Borghi builds
the “Villages of Ignis,” with affordable one- and two-family
houses (Borghi Villages), as well as a pool and sports center
in Comerio, Italy, and a hostel vvith recreational facilities for
young workers in Cassinetta, Italy, all intended to promote a
comfortable, healthy lifestyle.

  The Milan industrialist Giovanni Borghi founded the IGNIS brand of household appliances.  His factories would turn out one appliance every eight seconds, and make billions selling them to Italy's exploding middle class.   Borghi was famous for his early support of cycling, and his yellow IGNIS jerseyed squadra won more than a few great races in the late fifties and early sixties.

Borghi was aggressive, flamboyant and flashy.  And he took care of his stars - famously buying Spanish sprinter Miguel Poblet a Lancia convertible after his Milan San Remo win.   On top of his 25 million lire per year salary.  

Giovanni Borghi, was an Italian industrialist pioneer in the field of domestic appliances, returned from a trip in the USA with a real
illumination: refrigerators insulated with Polyurethane foam were much more
efficient and capacious than those hand-filled with mineral wood.
His refrigerators Group, Ignis, developed internally this technology and the
related equipment, a suitable alternative to the imported foam dispensers, which
were difficult to get, fix and maintain, stimulating an industrial supply of
similar machines.  

 And in 1959 Borghi signed the man most of Italy thought would be the man to replace Fausto Coppi:  1956 Olympic, 1958 Giro d'Italia and World Champion  Ercole Baldini.  He lured Baldini away from Legnano with a contract so fat many said it only served to asurre that il treno di Forli.. would...well...get a little too fat himself!  He was never quite as hungry once he went to IGNIS.

Borghi kept control of IGNIS in the family.  In the paternalistic Italian industrial model - like Ferrari, Maserati or Campagnolo.   He later turned the reins over to his son, who in turn finally sold the company to Dutch conglomerate, Philips.
 
When Philips decided to get into the major household appliances
market, its procedure was to buy increasing quantities of these goods from the Italian firm, Ignis, then at the height of its prosperity.
Once it became the principal client of the manufacturer, it took over supplying the latter by purchasing 50 percent of its capital. It took over the firm completely in 1972, to the satisfaction of the founder of Ignis, Giovanni Borghi. 

BORGHI DIED IN 1975.
 
Borghi is still remembered in Italia.   RAI even aired TV miniseries about his life this past year, "Mister Ignis".
