In general, an air conditioner for heating and cooling is installed in a vehicle. The air conditioner includes a compressor for compressing a low temperature low pressure refrigerant drawn from an evaporator into a high temperature high pressure refrigerant and sending it to a condenser as a configuration of a cooling system. A swash plate compressor is used.

The swash plate compressor is driven according to the on / off of the air conditioner switch installed on the front panel of the vehicle. 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.

In the swash plate type compressor, a swash plate having a predetermined angle of inclination is installed on a rotating shaft provided in the compressor, and the piston in the cylinder bore connected to the swash plate compresses the refrigerant by reciprocating in conjunction with the rotation of the rotating shaft.

Such swash plate type compressors include fixed displacement type and variable displacement type. In general, the discharge capacity of the variable displacement swash plate type compressor is achieved by controlling the inclination angle of the swash plate. When the cooling load increases, the inclination angle of the swash plate increases, and when the cooling load decreases, the inclination angle of the swash plate decreases. For reference, the inclination angle of the swash plate means the angle formed between the surface perpendicular to the drive shaft and the swash plate.

As shown in FIG. 4, the compressor 100 of the present invention includes a cylinder block 110 having a plurality of cylinder bores 111 and a crank chamber 121 coupled to the front of the cylinder block 110. Front housing 120 to form a, and the rear housing 130 is coupled to the rear of the cylinder block 110 to form a suction chamber 131 and the discharge chamber 133.

A plurality of cylinder bores 111 are radially formed at regular intervals in the cylinder block 110. The cylinder bore 111 is a portion for compressing the refrigerant, and the pistons 140 are accommodated therein so that the piston 140 linearly reciprocates and compresses the refrigerant in the space therebetween. The cylinder bore 111 is formed in a cylindrical shape to penetrate the cylinder block 110, and the piston 140 is formed in a cylindrical shape corresponding thereto.

One side of the cylinder block 110, that is, the front housing 120 is coupled to the front. The rear of the front housing 120 is formed concave, in cooperation with the cylinder block 110 to form a crank chamber 121 therein. In addition, a driving unit 160 for reciprocating the piston 140 is installed in the crank chamber 121 formed between the cylinder block 110 and the front housing 130.

The rear housing 130 is installed on the opposite side of the cylinder block 110, the front housing 120 is installed. In the rear housing 130, a suction chamber 131 is formed at the center of the surface facing the cylinder block 110 to suck the refrigerant. The suction chamber 131 temporarily stores a refrigerant to be compressed into the cylinder bore 111.

The rear housing 130 is formed with a discharge chamber 133 through which the refrigerant compressed by the cylinder bore 111 is discharged. The discharge chamber 133 is formed at a portion corresponding to the outer side in the rear housing 130 of the portion corresponding to the cylinder bore 111.

The rear housing 130 is formed with a suction port 135 which serves to transfer the refrigerant into the suction chamber 131. The suction port 135 is formed to penetrate so that the outside of the compressor 100 and the inside of the suction chamber 131 are connected to each other.

Between the cylinder block 110 and the rear housing 130, a valve assembly 150 for controlling the flow of the refrigerant between the suction chamber 131 and the discharge chamber 133 is provided. The suction chamber 131 and the discharge chamber 133 are selectively in communication with the cylinder bore 111 by the pressure difference with the cylinder bore 111 to move the refrigerant. At this time, the valve assembly 150 regulates the flow of the refrigerant based on the pressure difference between the cylinder bore 111, the suction chamber 131, and the discharge chamber 133.

Next, a configuration for driving the piston 140 for compressing the refrigerant while performing a linear reciprocating motion in the cylinder bore 111 will be described.

The driving source for operating the piston 140 is a driving force transmitted from the engine of the vehicle. The driving force in the engine is transmitted to the drive shaft 161 so that the drive shaft 161 rotates. The drive shaft 161 is coupled to the center bore formed in the rear center of the cylinder block 110 through the shaft hole formed in the front housing 120. The drive shaft 161 is rotatably supported based on the rotational force transmitted from the engine.

In addition, the drive shaft 161 is provided with a swash plate 180 for reciprocating the piston 140. The swash plate 180 is formed in a disc shape, and is installed to change an angle with respect to the drive shaft 161 according to the discharge capacity of the compressor. That is, the swash plate 180 is coupled to the drive shaft 161 so that the swash plate 180 can be changed to be perpendicular to the drive shaft 161 or inclined at a predetermined angle with respect to the drive shaft 161.

A hemispherical shoe 144 is provided at one side of the piston 140 that performs the linear reciprocating motion, that is, in the front of the connecting portion 142 for connection with the swash plate 180. An edge portion of the swash plate 180 is coupled between the shoes 144. Therefore, when the swash plate 180 having a predetermined inclination rotates and an edge portion passes the shoe 144, the swash plate 180 is connected to the connection part 142 having the shoe 144 by the inclination of the swash plate 180. The piston 140 compresses the refrigerant while linearly reciprocating in the cylinder bore 111.

In order to adjust the inclination angle of the swash plate 180, a control valve (not shown) is installed at one side of the rear housing 130. The control valve is provided with a valve unit (not shown) that can selectively communicate the discharge chamber 133 and the crank chamber 121. The control valve controls the pressure in the crank chamber 121 by controlling a flow rate while guiding a part of the refrigerant of the discharge pressure discharged from the discharge chamber 133 through the valve unit to the crank chamber 121.

That is, the inclination angle of the swash plate 180 can be changed by changing the pressure of the crank chamber 121, and accordingly, the stroke of the piston 140 is changed to adjust the discharge amount of the refrigerant. It is a control valve to control such that the indoor pressure of the crank chamber 121 can be changed.

On the other hand, one side of the rear housing 130 is formed with a suction port 135 through which the refrigerant flows into the suction chamber 131 from the outside of the compressor. The suction port 135 is provided with a suction check valve 190 to selectively block the movement of the refrigerant.

5 and 6, the suction check valve 190 includes a base 197 in which a suction hole is formed, a case 191 coupled to the base 197, and a suction hole 192 is formed, A core 195 coupled between the base 197 and the case 191 to selectively communicate the suction hole with the suction hole 192, and the core 195 providing elastic force in a direction in which the suction hole is closed. It includes an elastic member (199).

A suction hole is formed in the center of the base 197, and the case 191 is coupled to the base 197. The case 191 is formed in a hollow cylindrical shape, the surface coupled to the base 197 is open. The core 195 is coupled to an empty space inside the case 191. A plurality of suction holes 192 are formed on the outer surface of the case 191 to selectively communicate with the suction holes by the core 195.

The core 195 is formed in a hollow cylindrical shape, and the surface facing the case 195 is open. The elastic member 199 is mounted in the inner empty space of the core 195. An elastic member 199 is coupled between the case 191 and the core 195. The elastic member 199 provides an elastic force in a direction in which the core 195 closes the suction hole.

An assembly protrusion 192 protrudes from a lower end of the case 195, that is, the opposite side of the base 197. The assembly protrusion 192 may be formed in a partial sphere shape. In the embodiment of the present invention, the assembling protrusion 192 is formed in a partial sphere shape, but is not necessarily limited to being formed in such a shape. For example, the assembly protrusion 192 may be formed in a polygonal shape with a portion of a cross section of a triangle or more.

An assembly groove 137 is formed at one side of the rear housing 130. In more detail, the assembling groove 137 is formed in the inner wall in which the suction chamber 131 is formed in the rear housing 130. The assembly groove 137 is formed in a shape corresponding to the assembly protrusion 192. The assembly protrusion 192 is fitted into the assembly groove 137, and the suction check valve 190 is coupled to the rear housing 130.

Next, a method of assembling the suction check valve 190 according to the present invention to the rear housing 130 will be described.

The user inserts the suction check valve 190 into the suction port 135 and forcibly inserts the cooking protrusion 192 formed in the suction check valve 190 into the assembly groove 137 formed on the inner wall of the suction chamber 131. Once installed, assembly is complete.

When the suction check valve 190 is assembled as in the present invention, since the suction check valve 190 is not press-fitted into the suction port 135 as in the prior art, it is not necessary to secure the strength of the press-fit part. That is, since it is not necessary to increase the strength of the base 197 in which the suction hole is formed, it becomes possible to design the suction diameter R2 of the suction hole formed in the base 197 large. Therefore, the refrigerant flowing into the suction chamber 131 through the suction port 135 can be smoothly introduced to improve the performance of the compressor.

In addition, since it is not necessary to design the strength of the suction check valve 190 large, it is possible to design the material of the suction check valve 190 as a light and soft material such as plastic, thereby reducing the weight of the parts and reducing the manufacturing cost. Will be.
