[0001] Gasket for variable swash plate compressor [0002]

The present invention relates to a gasket for a compressor, and more particularly, to a gasket for a compressor, in which a plurality of protrusions are formed in a rear housing direction in a body portion which is a non- The suction force of the supply line on the assembly line in the stacked gasket mounting part improves the separability of the stacked gasket when one gasket is drawn out, thereby improving the efficiency of assembly work of the compressor, To a gasket for a compressor.

Generally, an automobile is provided with an air conditioner (A / C) for cooling and heating the room. Such an air conditioner includes a compressor that compresses gaseous low-temperature and high-pressure gaseous refrigerant introduced from an evaporator into gaseous refrigerant of high temperature and high pressure and sends it to a condenser.

The compressor includes a reciprocating type compressing the refrigerant by the reciprocating motion of the piston in accordance with the compressing system, and a rotary type compressing by the rotational motion. The reciprocating type includes a crank type in which a crank is used in accordance with a transmission system of a drive source, and a swash plate type in which a crank is transmitted to a plurality of pistons. Rotary types include rotary rotary axes using vanes, vane rotary, rotary scrolling, and scrolling with fixed scrolling.

Among the reciprocating compressors described above, the swash plate type compressor is formed to rotate the swash plate while rotating the rotary shaft by the driving force of the engine, and reciprocate the piston in accordance with the rotation of the swash plate to compress the refrigerant.

Generally, a variable capacity swash plate type compressor refers to a compressor in which a swash plate of a swash plate type compressor is configured to be able to change the inclination angle of swash plate in accordance with the compression capacity.

Such a swash plate type compressor is driven in accordance with on / off of the air conditioner switch. When the compressor is driven, the temperature of the evaporator is lowered, and when the compressor is stopped, the temperature of the evaporator is increased. When the air conditioner switch is turned on, the swash plate type compressor discharges refrigerant having a high pressure according to the relative motion between the piston, the rotary shaft and the swash plate to the condenser outside the compressor.

1 is a cross-sectional view of a conventional variable displacement swash plate type compressor 1. A schematic configuration of a conventional variable displacement swash plate type compressor will be described with reference to FIG.

The cylinder block (10) forms part of the skeleton and the outer appearance of the variable swash plate type compressor (1). A center bore 12 is formed through the center of the cylinder block. A rotary shaft (40) is rotatably mounted on the center bore (12).

A plurality of cylinder bores 11 are formed so as to penetrate the cylinder block 10 radially around the center bore 12.

A piston (13) is installed in the cylinder bore (11) so as to reciprocate linearly. Preferably, the piston 13 is formed in a cylindrical shape, and the cylinder bore 11 is formed in a cylindrical space so as to correspond to the shape of the piston 13.

Accordingly, the piston 13 linearly reciprocates inside the cylinder bore 11 and compresses the refrigerant sucked through the suction chamber 31.

A front housing (20) is installed at one end of the cylinder block (10). The front housing 20 is recessed in a direction opposite to the cylinder block 10 to form a crank chamber 21 together with the cylinder block 10 therein. The crank chamber 21 is kept air-tight with the outside.

A pulley can be rotatably installed on one side of the front housing 20. [ The pulley receives the driving force of the engine and rotates the rotating shaft.

The rear housing 30 is installed to face the front housing 20 at the other end of the cylinder block 10, that is, the cylinder block 10.

A suction chamber 31 is formed on the inner side by a circular partition wall formed in the rear housing 30 so as to communicate with the suction port through the suction passage 32. The suction chamber 31 functions to transfer the refrigerant to be compressed into the cylinder bore 11.

The discharge chamber 33 is formed on the outer side of the rear housing 30 by a circular partition wall formed therein. The discharge chamber 33 functions to temporarily store the compressed refrigerant before it is discharged to the outside of the compressor.

The center bore 12 and the crank chamber 21 of the front housing 20 to be rotatable. The rotary shaft (40) is rotated by the driving force transmitted from the engine. A rotor 41 is provided on the rotary shaft 40.

The rotor 41 penetrates the center of the rotating shaft 40 and is installed in the crank chamber 21 so as to rotate integrally with the rotating shaft 40. The rotor 41 is fixed to the rotary shaft 40 in a substantially disc shape and the hinge arm 42 protrudes from one surface of the rotor 41.

The swash plate 44 is installed to be connected to the rotary shaft 40 by a shoe 45. The swash plate 44 is hinged to the rotor 41 and rotates together with the rotor 41. The swash plate 44 is installed at a position between a state in which the swash plate 44 is perpendicular to the longitudinal direction of the rotary shaft 40 and a state in which the swash plate 44 is inclined at a predetermined angle with respect to the rotary shaft 40 do.

A semi-inclined spring 43, which is a coil spring, is installed on the rotary shaft 40 so as to surround the rotary shaft 40. The anti-tilt spring 43 exerts an elastic force between the rotor 41 and the swash plate 44. That is, the semi-inclined spring 43 functions to absorb the force acting on the swash plate 44 when the operation of the compressor 1 is stopped, by applying an elastic force in a direction in which the inclination angle of the swash plate 44 is reduced .

A valve unit (50) is installed between the cylinder block (10) and the rear housing (30) to control the flow of the refrigerant.

A gasket 100 is installed between the cylinder block 10 and the valve unit 50 and between the valve unit 50 and the rear housing 30. [

The gasket 100 for a conventional compressor is placed in a gasket mounting portion on the assembly line in the form of a stack of a plurality of gaskets of the same kind. That is, a variable swash plate type compressor assembly line is operated in a state where 50 to 200 gaskets of the same kind are stacked in the height direction and are placed on the gasket mounting portion on the assembly line.

As described above, since the gasket for a conventional compressor is placed in the stacking portion of the gasket in the form of a stack of a plurality of gaskets of the same kind, the load of the gasket itself causes overlapping between the gasket placed on the adjacent upper portion and the gasket placed on the lower portion .

When the gasket is drawn out by the suction force of the supply line on the assembly line in the stacking portion of the gasket stacked on the assembly line due to overlapping between the gasket placed on the adjacent upper portion and the gasket placed on the lower portion, (Or more gaskets) are drawn out, there is a problem that a separate work process or a worker must be input to prevent this.

In addition, in the conventional gasket for compressors, two or more gaskets are drawn out by the overlapping in a stacked state, thereby increasing the assembling time and assembling cost of the variable swash plate type compressor.

Conventionally, a gasket for a compressor has been formed by applying graphite powder to the upper portion of a gasket in order to solve the overlapping problem as described above.

However, such a powder layer has a problem that it can not completely solve the problem of layering of the gasket due to the load of the gasket itself, which is simply stacked with the graphite powder powder.

Further, in the conventional gasket for a compressor having a powder layer, the graphite powder forming the powder layer flows into the inside of the compressor in the state where the gasket is assembled to the compressor or the compressor is operated in the state where the gasket is assembled, There is a problem that the quality and performance of the compressor are deteriorated.

As shown in Figs. 2 to 3, a plurality of protrusions 140 are formed adjacent to the through-holes 111. Fig.

Further, the plurality of protrusions 140 are formed to protrude from the valve unit 50 toward the rear housing 30.

Although not limited thereto, the plurality of protrusions 140 may be formed through embossing forming during a forming operation.

Thus, the projections can be formed while minimizing the airtightness of the gasket itself and the deterioration of the watertightness maintaining function and the deformation that may occur in the main body.

The body portion 110, the peripheral portion 120, and the plurality of bending portions 130 are integrally formed of an alloy material having excellent heat resistance.

A communication hole 113 is formed through the main body 110 to communicate the crank chamber 21 and the suction chamber 31 or between the crank chamber 21 and the discharge chamber 33.

That is, the communication hole 113 is formed in the main body 110 through the main body 110 so that the through hole 111 and the plurality of coolant suction holes 112 do not overlap.

A plurality of refrigerant discharge holes 121 are formed through the peripheral portion 120.

That is, a plurality of coolant discharge holes 121 are formed through the peripheral portion 120 so as to be spaced apart from each other along the outer peripheral surface of the peripheral portion 120 at the same angle.

The refrigerant compressed through the plurality of refrigerant discharge holes 121 can be transferred to the discharge port.

A plurality of fastening holes 122 are formed through the circumference 120 to fasten the gasket 100 to the rear housing 30. [

That is, the plurality of fastening holes 122 are formed at the same angle along the outer peripheral surface of the peripheral portion 120 so as not to overlap with the plurality of refrigerant discharge holes 121.

The assembling guide pins are inserted into the plurality of fastening holes 122 so that the gasket can be easily fastened to the rear housing 30.

[ Are formed to face each other with respect to the center (C).

That is, the two protrusions 140 protrude from the imaginary straight line passing through the center C of the through hole 111 in the non-interference region (portion B in Fig. 2) between the through hole 111 and the refrigerant suction hole 112 Two of them are formed so as to face each other with respect to the center C of the through hole 111.

The two protrusions 140 are formed to face each other with respect to the center C of the through hole 111 so that the stacked gaskets are prevented from tilting to one side when a plurality of gaskets are stacked on the assembly line, It is possible to further improve the separability of the stacked gasket when one gasket is taken out by the suction force of the supply line on the assembly line.

3, the plurality of protrusions 140 of the gasket 100 for a compressor according to the embodiment of the present invention is formed in a non-interference region (see FIG. 3) between the through- At the same angle (?) On a concentric circle spaced from the center C of the through-hole 111. In this case,

The three protrusions 140 are formed so as to be spaced at the same angle alpha on the concentric circle spaced from the center C of the through hole 111 so that the upper gasket on which the lower gasket is stacked is stably supported Thus, it is possible to completely prevent the stacked gaskets from tilting to one side.

That is, three protrusions 140 are formed between the through holes 111 and the coolant suction holes 112 so as to be spaced by 120 degrees on the concentric circle spaced from the center C of the through holes 111.

If four protrusions 140 are formed, they are spaced apart by 90 degrees.

As described above, two or three or more protrusions 140 are provided between the through-holes of the main body portion and the coolant suction holes, which are non-interference regions (portions B in Figs. 2 and 3) The separating property of the stacked gasket can be improved when the one gasket is taken out by the suction force of the supply line on the assembly line in the stacking portion of the gasket stacked on the assembly line, And the convenience of the operator can be improved.

4, the curvature R of the upper surface 141 of each protrusion 140 of the gasket 100 for a compressor according to another embodiment of the present invention is greater than the curvature R of the upper surface 141 of each protrusion 140 Is formed to be larger than the curvature (r) of the surface (142).

That is, as shown in FIG. 5, when a plurality of gaskets are stacked, the upper portion of each of the protrusions 140 may be formed so as to maintain a constant gap D between a gasket stacked on the adjacent upper portion and a gasket stacked on the lower portion. The curvature R of the surface 141 is formed to be larger than the curvature r of the lower surface 142 of each protrusion 140. [

  Accordingly, when the single gasket is taken out by the suction force of the supply line on the assembly line, the separability of the stacked gasket can be maximized, and finally the assembling cost and assembly time of the variable swash plate type compressor can be reduced.

Although not shown in the drawing, each of the protrusions 140 may have a shape in which the tips of the protrusions 140 protrude more than the protrusions 140 shown in Figs. 4 to 5.

That is, each of the protrusions 140 may be formed such that the tip of each protrusion 140 protruding in the direction of the rear housing protrudes like a mountain.

4 to 5, the curvature R of the upper surface 141 of each protrusion 140 and the radius of curvature R of each protrusion 140 (not shown in the drawings) The curvature r of the lower surface 142 of the base portion 142 can be made smaller.

That is, each of the protrusions 140 is formed so that the curvature R of the upper surface 141 of each protrusion 140 is larger than the curvature r of the lower surface 142 of each protrusion 140 May be formed to have a curvature.

In this way, since the tip of each protrusion 140 is formed in a protruding shape like an acid, or each protrusion 140 is formed so as to have a gentler curvature than the semicircular shape, the protrusion 140 is formed through an embossing process , It is possible to minimize the formation time of the protrusion 140 and to reduce the manufacturing cost and the manufacturing cost of the gasket 100.

It is also possible to minimize the deformation of the protrusion 140 to minimize the deformation of the non-interference area (part B of FIG. 2 and FIG. 3) where the protrusion 140 is formed, And damage can be prevented.

As shown in FIG. 4, the height H of each protrusion 140 of the gasket 100 for a compressor according to another embodiment of the present invention is formed to be 0.3 mm or more and 1.0 mm or less.

When the height H of each protrusion 140 of the gasket 100 is less than 0.3 mm, it is impossible to maintain a constant gap D between the gasket stacked on the upper portion and the gasket stacked on the lower portion, It is not possible to achieve the purpose of maximizing the separability of the stacked gaskets when the gaskets are drawn out by the suction force of the gasket.

When the height H of each protrusion 140 of the gasket 100 exceeds 1.0 mm, the main body 110 of the gasket 100 may be punctured or broken at the time of embossing. That is, when the height H of the protrusion 140 exceeds 1.0 mm, the rigidity of the main body 110 is lowered, so that the main body of the gasket is broken during driving of the variable swash plate type compressor, And the watertightness maintaining function can not be performed.

As described above, since the plurality of protrusions 140 are formed through embossing forming in the forming operation and no separate powder layer is formed, the cost is reduced as the assembly process is reduced, It is possible to improve the quality of the variable swash plate type compressor and increase the efficiency of the compressor.

6, the gasket 100 for a compressor according to an embodiment of the present invention further includes a body layer 110 and a rubber layer 150 formed on a top surface and a bottom surface of the protrusion 140 .

Although not limited thereto, the rubber layer 150 may be formed of a sealing member such as rubber, so as to alleviate the shock when the gasket is impacted, and enhance the airtightness and watertightness maintaining function.

The present invention is not limited to the modifications shown in the drawings and the embodiments described above, but may be extended to other embodiments falling within the scope of the appended claims.
