Description

[0001] SWASH PLATE TYPE COMPRESSOR [0002]

The present invention relates to a swash plate type compressor, and more particularly, to a swash plate type compressor which compresses a refrigerant sucked from an external refrigerant line by a plurality of reciprocating pistons in accordance with rotation of a swash plate, And the opening degree of the suction check valve mounted between the chambers can be appropriately adjusted according to the amount of refrigerant sucked from the refrigerant line.

Generally, compressors that serve to compress refrigerant in automotive cooling systems have been developed in various forms. Such a compressor includes a reciprocating type in which compression is performed while a refrigerant is compressed and a rotary type in which compression is performed while rotating. In the reciprocating type, there are a crank type in which the driving force of the drive source is transmitted to a plurality of pistons by using a crank, a swash plate type in which the swash plate is transmitted by a swash plate installed shaft, a wobble plate type in which a wobble plate is used, There are vane rotary type, scroll type using revolving scroll and fixed scroll.

Among the above various types of compressors, the swash plate type compressor is driven according to 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 raised.

On the other hand, as the swash plate type compressor, there are fixed capacity type and variable capacity type. These compressors are driven by receiving power from the rotational force of the engine of the vehicle. In the fixed capacity type, an electromagnetic clutch is provided to control the operation of the swash plate type compressor. However, in the case of the fixed capacity type having the electromagnetic clutch, there is a problem that the RPM of the vehicle flows when the compressor is driven or stopped, thereby hindering stable vehicle operation.

Therefore, in recent years, a variable displacement type, which is not provided with a clutch, is always driven with the driving of the engine of the vehicle, and can vary the discharge capacity by changing the inclination angle of the swash plate, is widely used. In such a variable displacement swash plate type compressor, a pressure control valve for adjusting the inclination angle of the swash plate is generally used for adjusting the refrigerant discharge amount.

However, in the conventional variable displacement swash plate type compressor, when the suction amount of the refrigerant is decreased, there is a problem that vibration occurs in the suction port and pulsation or roar occurs.

In order to solve such a problem, a suction check valve 150 shown in FIG. 1 has been proposed in order to gradually change the flow area of the suction port when the suction amount of refrigerant is small to avoid abrupt suction.

The suction check valve 150 includes a case 151, an opening and closing core 153 and a recoil spring 155. The case 151 is a cylindrical body that is opened to serve as a body of the valve 150 And an opening cover 169 is fitted around the opened suction port 161. A discharge port 163 is formed at one side of the side wall surface at a right angle to the suction port 161. [

The opening and closing core 153 is a cylindrical plunger which is installed inside the case 151 so as to be movable in an axial direction and moves up and down inside the case 151 in accordance with the refrigerant pressure applied to the suction port 161, To the discharge port 163, as shown in FIG.

The recoil spring 155 is installed to elastically support the opening / closing core 153 against the pressure of the refrigerant flowing into the case 151 through the suction port 161. The refrigerant pressure The opening / closing core 153 is brought into close contact with the cover 169 so that the suction port 161 can be closed.

The axial groove 171 is formed on the outer peripheral surface of the opening and closing core 153 so that the refrigerant can flow through the axial groove 171 even when the opening and closing core 153 is in close contact with the lid 169 So that a sudden change in the opening of the suction check valve can be prevented even if there is a sudden change in the refrigerant pressure applied to the suction port 161. [

However, in the case of the conventional suction check valve 150 as described above, a lid formed to have a lid or an engagement structure of a metal material is installed for installation in the compressor while restricting movement of the opening / closing core 153. Accordingly, when a cover made of a metal material is applied, the suction check valve 150 is installed inside the compressor by press-fitting, and when the cover formed to have a coupling structure is applied, the suction check valve 150 is inserted into the compressor Installed.

However, when the above conventional installation structure is followed, a separate part such as a cover made of a metal material or a cover formed to have a coupling structure has to be used, so that the number of assembling holes increases and manufacturing cost increases.

SUMMARY OF THE INVENTION It is an object of the present invention to provide a suction check valve and a suction check valve, And it is an object of the present invention to provide a swash plate type compressor in which a lid which has been used as a conventional separate part becomes unnecessary, thereby reducing the number of assembling steps and reducing manufacturing cost.

2 to 8, a swash plate compressor according to an embodiment of the present invention includes a housing 100, a rotary shaft 200, a swash plate 300, a plurality of pistons 400, (500).

3 and 4, the housing 100 includes a cylinder block 110, a front head 120, and a rear head 130. As shown in FIGS. Here, the cylinder block 110 is a tubular body disposed at an intermediate portion in the longitudinal direction of the housing 100, and a hollow portion is formed therein to house the plurality of pistons 400 as well as the rotary shaft 200 .

The front head 120 and the rear head 130 are cylinders for closing the open and close ends of the upper cylinder block 110. As shown in FIGS. 3 and 4, the front head 120 includes a cylinder block 110 So that the inclination adjusting mechanism 320 can be received while securing the crank chamber 121 which is the rotating space of the swash plate 300. [

The rear head 130 has a front end open toward the cylinder block 110 and includes a suction chamber 132 for supplying the refrigerant to the cylinder bore 111 of the cylinder block 110 during the suction stroke, A discharge chamber 134 through which the refrigerant in the cylinder bore 111 is discharged is formed. A suction port 131 and a discharge port (not shown), which are connected to the suction chamber 132 and the discharge chamber 134, respectively, are formed on an outer wall surface of the rear head 130. On the other hand, a suction check valve 500 is mounted on the channel 135 connecting the suction port 131 to the suction chamber 132.

3 and 4, the rotating shaft 200 is a means for transmitting the rotational driving force of the external driving source to the inside of the compressor. The rotating shaft 200 penetrates a central portion of the front head 120, And is rotatably mounted. A rotary pulley 140 is coupled to one end of a rotary shaft 200 exposed to the outside of the front head 120 and an external rotary driving force is transmitted to the rotary shaft 200 through the rotary pulley 140 The rotating shaft 200 is rotated.

3, the swash plate 300 is mounted on the rotary shaft 200 in an inclined state. The swash plate 300 is a member for converting the rotational driving force of the rotary shaft 200 into reciprocating linear motion of the piston 400, And rotates together with the rotating shaft 200. At this time, a plurality of shoes 310 are mounted in the circumferential direction of the swash plate 300, and the plurality of pistons 400 are slidably supported by the shoe 310 through the shoe 310.

In particular, the swash plate type compressor shown in FIGS. 3 and 4 is a variable displacement swash plate type compressor. The swash plate type compressor is installed such that the inclination angle of the swash plate 300 is variable, Is 90 DEG, the reciprocation motion of the piston 400 disappears, so that the rotation shaft 200 idles. Conversely, when the swash plate 300 is inclined with respect to the rotary shaft 200 as shown in FIG. 3, the piston 400 reciprocates in the cylinder bore 111 to compress the refrigerant.

The suction check valve 500 installed on the pipeline 135 between the suction port 130 and the suction chamber 132 through which the refrigerant flows from the outside is connected to the suction check valve 500 when the slope of the swash plate 300 approaches 90 °, The amount of inflow of the refrigerant becomes small, and on the contrary, when the inclination becomes smaller than 90 degrees, the inflow amount of the refrigerant increases, thereby increasing the opening degree.

The plurality of pistons 400 are means for compressing the refrigerant while reciprocating in the cylinder bore 111 by the swash plate 300. As shown in FIGS. 3 and 4, And is reciprocated linearly along the inner peripheral surface of the cylinder bore 111 of the cylinder block 110 by the rotation of the swash plate 300, The refrigerant sucked into the cylinder bore 111 through the discharge port 131 is discharged to an external refrigerant line through a discharge port (not shown) of the rear head 130.

In the swash plate type compressor according to the present invention, the suction check valve 500 whose opening degree is adjusted according to the amount of refrigerant flowing through the suction port 131 is connected to the suction chamber 131 through a pipe connecting the suction port 131 to the suction chamber 132 A case 510 provided on one side of the case 510 and having a suction port 511 formed on one side thereof and a discharge port 512 communicating with the suction port 511 on the other side thereof; And an opening / closing core 520 which is movably installed through a spring (not shown) to adjust the flow of refrigerant from the inlet 511 to the outlet 512 (see FIG. 7), and the case 510 Includes a bump structure part 530 which restricts the movement of the opening and closing core 520 and allows the outer circumference of the case 510 to be fixed to the housing part 135a formed in the conduit 135. [

The first embodiment shown in Fig. 4 and the second embodiment shown in Fig. 5, A third embodiment shown in FIG. 6, and a fourth embodiment shown in FIGS.

Hereinafter, a first embodiment of the bump structure 530 shown in FIG. 4 will be described. In the case of the first embodiment of the bump structure 530, the inner bump 531 and the outer bump 532 are located at the upper end of the case 510 as shown.

Further, the inner bump 531 and the outer bump 532 are integrally formed on the same circumference of the case 510. The inner bump 531 includes an inclined surface 531a for guiding the opening and closing core 520 to be smoothly inserted into the case 510, And an engagement surface 531b for restricting upward movement of the engagement portion 520. [

Therefore, when the opening / closing core 520 is inserted into the case 510, the opening / closing core 520 can be easily installed due to the inclined surface 531a formed on the inner bump 531, After the core 520 is installed inside the case 510, the opening / closing core 520 is released from the upper end of the case 510 by the engagement surface 531b formed on the inner bump 531, Rise is regulated.

The outer bump 532 is inserted into the housing frame 135a formed in the conduit 135 and is hooked when the case 510 is installed in the conduit 135. Therefore, So that it can be firmly fixed to the channel 135.

Hereinafter, the second embodiment of the bump structure 530 shown in FIG. 5 will be described, and the description of the features overlapping with the first embodiment of the bump structure 530 described above will be omitted. In the case of the second embodiment of the bump structure 530, the inner bump 531 and the outer bump 532 are located at the upper end of the case 510 and are integrally formed on the same circumference of the case 510 And the inclined surface 531a and the engaging surface 531b are formed on the inner bump 531 are the same as those of the first embodiment of the bump structure portion 530 described above. However, the second embodiment of the bump structure 530 differs from the first embodiment of the bump structure 530 in a specific cross-sectional shape as shown in FIG. 5, and this difference is due to the length of the outer bump 532 And is formed so as to protrude to the outside of the case 510 only at a position adjacent to the upper end of the case 510. [

In the case of the second embodiment of the bump structure portion 530, the inner bump 531 and the outer bump 532 are attached to the case 510 in such a manner that the inner bump 531 and the outer bump 532 can be moved inwardly and outwardly of the case 510, And a U-shaped cutout hole 510a is formed through the U-shaped cutout hole 510a.

The inner bump 531 and the outer bump 532 are inserted into the case 510 when the opening and closing core 520 is inserted into the case 510. In this case, So that the opening / closing core 520 can be easily installed through the operation. The outer bump 532 is formed in the housing frame 135a formed in the conduit 135 in the process of installing the case 510 in the conduit 135, The inner bump 531 and the outer bump 532 can be moved in the inner direction of the case 510 when the inner bump 531 and the outer bump 532 are compressed by the inner circumferential surface of the pipe 135 before being inserted, 510) can be more easily installed.

Hereinafter, a third embodiment of the bump structure 530 shown in FIG. 6 will be described, and a description of the features that are the same as those of the first embodiment of the bump structure 530 described above will be omitted. The inner bump 531 and the outer bump 532 are located at the upper end of the case 510 and are integrally formed on the same circumference of the case 510 in the case of the third embodiment of the bump structure 530 And the inclined surface 531a and the engaging surface 531b are formed on the inner bump 531 are the same as those of the first embodiment of the bump structure portion 530 described above. However, the third embodiment of the bump structure 530 differs from the first embodiment of the bump structure 530 in a specific cross-sectional shape as shown in FIG. 6, and this difference is due to the length of the outer bump 532 And is formed so as to protrude to the outside of the case 510 from a predetermined position adjacent to the upper end of the case 510.

In the third embodiment of the bump structure 530, a wing protrusion 533 formed in a curved shape along the circumferential direction is formed in the outer bump 532, and the wing protrusion 533 extends in the pipe 135 are formed so as to be curved upward so as to absorb the axial tolerance within the housing grove 135a formed in the housing part 135a. When the case 510 is installed in the duct 135 and the outer bump 532 is inserted into the housing frame 135a formed in the conduit 135, the outer bump 532 and the housing frame 135a, The axial movement of the case 510 due to the axial tolerance and the corresponding noise are prevented because the wing protrusion 533 is resiliently supported in the axial direction within the housing groove portion 135a .

Hereinafter, a fourth embodiment of the bump structure portion 530 shown in Figs. 7 and 8 will be described. As shown in the figure, the inner bumps 531 are formed to protrude from the inner circumferential surface of the case 510 at regular intervals, and the outer bumps 532 are formed on the inner surface of the case 510, And are formed so as to be protruded from the outer circumferential surface of the base plate 510 at regular intervals. The outer bumps 532 are arranged to have a constant phase difference in the circumferential direction with respect to the inner bumps 531. The inner bump 531 includes an inclined surface 531a for guiding the opening and closing core 520 to be smoothly inserted into the case 510, And an engagement surface 531b for restricting upward movement of the engagement portion 520. [ Therefore, when the opening / closing core 520 is inserted into the case 510, the opening / closing core 520 can be easily installed due to the inclined surface 531a formed on the inner bump 531, After the core 520 is installed inside the case 510, the opening / closing core 520 is released from the upper end of the case 510 by the engagement surface 531b formed on the inner bump 531, Rise is regulated.

The outer bump 532 is inserted into the housing frame 135a formed in the conduit 135 and is hooked when the case 510 is installed in the conduit 135. Therefore, So that it can be firmly fixed to the channel 135.

A first escape space A for compensating for a collapse of a portion where the inner bumper 531 is positioned when the opening / closing core 520 is inserted into the case 510 is formed on an inner circumferential surface of the case 510, Is formed between the inner bumper 531 and the first escape space A is formed by connecting the boundary B between the inner bumper 531 and the first escape space A It is preferable that the area of the closed graphic form on the cross section is formed to be similar to the cross sectional area of the opening / closing core 520.

This size limitation may be such that when the opening and closing core 520 is inserted into the case 510, the inside of the case 510 can be sufficiently collapsed so that the opening and closing core 520 can be inserted smoothly, 520 are installed and restored to their original shapes, an excessively large gap may not be formed between the case 510 and the opening / closing core 520. This is because if a too large gap is formed between the case 510 and the opening / closing core 520, noise may be generated.

A second escape space B for compensating for the collapse of a portion where the outer bumper 532 is located when the case 510 is installed in the duct 135 is formed on the outer circumference of the case 510, The second escape space B is formed between the outer bumper 532 and the second escape space B in the inner circumferential surface D of the conduit 135, Sectional area formed by connecting the outer circumferential surface of the case 510 formed with the outer circumferential surface of the outer circumferential surface of the outer circumferential surface of the case 510. [

This size limitation is achieved when the outer bump 532 passes through the inner circumferential surface of the conduit 135 before being inserted into the housing groove portion 135a formed in the conduit 135 in the process of installing the case 510 on the conduit 135 The outer bump 532 is inserted into the housing frame portion 135a while allowing the outer side of the case 510 including the outer bump 532 to be sufficiently collapsed so that the outer bump 532 can be inserted smoothly, The gap between the case 510 and the pipe 135 may not be formed when the pipe 510 is restored to its original shape again. This is because noise may be generated when an excessively large gap is formed between the case 510 and the channel 135.
