In addition, the present invention relates to a valve assembly of a vehicle compressor that increases the simplicity of configuration and ease of assembly by integrally forming the valve plate, the reed valve and the retainer by a riveting coupling.

일반적으로 자동차에는 여름철 실내의 환경을 쾌적하게 유지하기 위해 냉각된 공기를 실내에 주입하여 냉방을 이룰 수 있도록 함과 동시에 실내 공기청정을 하기 위한 에어컨 공기조화장치가 구비되어 있다.In general, in order to maintain the indoor environment comfortably in the summer, the vehicle is equipped with an air conditioner air conditioner for injecting cooled air into the room to achieve cooling and at the same time cleaning the indoor air.

이러한 에어컨 공기조화장치는 도 1에 도시되는 바와 같이, 압축기(100)에서 토출된 고온 고압의 냉매 가스를 콘덴서(101)로 액화시키고, 팽창 밸브(102)로 팽창시키는 것에 의해 저온, 저압의 상태로 만들고, 증발기(103)로 인한 잠열에 의해 주위의 공기를 냉각시킨 후, 에어컨 시스템 내에서 적정량의 냉매 유지 및 수분제거 기능을 하는 어큐물레이터(104)를 거쳐 다시 압축기(100)로 흡입시키는 순환 사이클을 구성하도록 되어 있다.As shown in FIG. 1, the air conditioner air conditioner is a state of low temperature and low pressure by liquefying a high temperature and high pressure refrigerant gas discharged from the compressor 100 into a condenser 101 and expanding it with an expansion valve 102. After cooling the surrounding air by latent heat due to the evaporator 103, and then sucked back into the compressor 100 through the accumulator 104 to maintain a proper amount of refrigerant and remove moisture in the air conditioning system. It is configured to constitute a circulation cycle.

도 2는 일반적인 자동차용으로 사용되는 사판형 압축기를 나타낸 도면이다.2 is a view showing a swash plate type compressor used for a general automobile.

도면을 참조하면, 사판형 압축기(100)는 복수의 실린더 보어(111)를 가지는 실린더 블록(100)이 중앙부에 배치되어 있고, 그 실린더 보어(111)에는 피스톤(120)이 전 후 유동가능하게 설치되어 있다. 그 실린더 블록(110)의 전방단은 밀폐상태의 크랭크실(131)을 형성하는 전방 하우징(130)에 의하여 폐쇄되어 있고, 그 후방단은 밸브 플레이트(144)을 거쳐 후방 하우징(140)에 의하여 폐쇄되어 있다. 후방 하우징(140)에는 실린더 보어(111)와 연통하는 흡입실(141) 및 토출실(142)이 형성되어 있다.Referring to the drawings, in the swash plate type compressor 100, a cylinder block 100 having a plurality of cylinder bores 111 is disposed at a central portion thereof, and the cylinder bore 111 has a piston 120 so as to be movable back and forth. It is installed. The front end of the cylinder block 110 is closed by the front housing 130 forming the crank chamber 131 in a closed state, and the rear end thereof is passed by the rear housing 140 via the valve plate 144. It is closed. The rear housing 140 is formed with a suction chamber 141 and a discharge chamber 142 in communication with the cylinder bore 111.

그리고, 실린더 블록(110)과 전방 하우징(130) 사이의 크랭크실(131)에는 구동축(150)이 실린더 보어(111)의 길이 방향으로 평행하게 설치되어 있다. 그 구동축(150)의 후단부는 실린더 블록(110)의 중심축공(113)에, 전단부는 전방 하우징(130)의 중심축공(132)에 베어링을 통해 지지되어 있다.In the crank chamber 131 between the cylinder block 110 and the front housing 130, a drive shaft 150 is provided in parallel in the longitudinal direction of the cylinder bore 111. The rear end of the drive shaft 150 is supported by the central shaft hole 113 of the cylinder block 110, and the front end portion is supported by the central shaft hole 132 of the front housing 130 via a bearing.

또한, 구동축(150)의 중심축공(113)과 중심축공(132) 사이에는 소켓사판(161)이 설치되어 있고, 이 소켓사판(161)의 일측단에는 크랭크실(131)에 축방향으로 설치된 가이드로드(162)가 전후 유동가능하게 계합되어 있다.In addition, a socket swash plate 161 is provided between the central shaft hole 113 and the central shaft hole 132 of the drive shaft 150, and one side end of the socket swash plate 161 is provided in the crank chamber 131 in the axial direction. The guide rod 162 is engaged to be movable back and forth.

이렇게 하여 구동축(150)이 회전함에 따라 소켓사판(161)이 경사진 상태로 회전하여 피스톤(120)이 좌우로 왕복 운동하여 실린더 보어(111)내의 냉매를 압축하게 된다.As the drive shaft 150 rotates in this way, the socket swash plate 161 rotates in an inclined state, and the piston 120 reciprocates from side to side to compress the refrigerant in the cylinder bore 111.

이에 따라 피스톤(120)의 왕복 운동과정에서 후방 하우징(140)의 흡입실(141)의 흡입실(141)에서 실린더 보어(111) 내에 냉매 가스가 흡입되고, 냉매 가스 는 압축된 후 토출실(142)로 토출된다.Accordingly, the refrigerant gas is sucked into the cylinder bore 111 in the suction chamber 141 of the suction chamber 141 of the rear housing 140 during the reciprocating motion of the piston 120, and the refrigerant gas is compressed and then discharged into the discharge chamber ( 142 is discharged.

이때, 압축된 냉매가 토출실(142)로 토출되기 위해서는 얇은 판상의 리드밸브(143)를 통과하여야 하는데, 이 리드밸브(143)는 양단의 압력차 즉, 토출실(142)과 실린더 보어(111) 내부의 냉매 압력차에 의해 휘어져 개방되도록 되어 있다.At this time, in order to discharge the compressed refrigerant to the discharge chamber 142, the thin plate-like reed valve 143 must pass through the reed valve 143, which is the pressure difference between both ends, that is, the discharge chamber 142 and the cylinder bore ( 111) It is bent and opened by the internal refrigerant pressure difference.

따라서, 압축기의 밸브 구조는 리드 밸브(143)의 냉매의 압력으로 인한 손상의 방지를 위해 리테이너(145)를 장착하여 밸브 플레이트(144)와의 사이에서 리드밸브(143)를 압박하여 리드밸브(143)에 가해지는 충격을 완충하는 구조로 되어 있다.Therefore, in the valve structure of the compressor, in order to prevent damage due to the pressure of the refrigerant in the reed valve 143, the retainer 145 is mounted to press the reed valve 143 between the valve plate 144 and the reed valve 143. It has a structure to cushion the shock applied to the).

또한 도 3 및 도 4에 도시된 바와 같이 종래의 압축기의 밸브 구조는 통상 금속으로 구성된 밸브 플레이트(144)와 양면에 별도의 가스켓(170) 재질의 실링 부재를 밸브 플레이트(144)와 접속되어 조립되도록 하거나 오링(171) 등의 실링재를 별도로 삽입하여 실린더 보어(111)와 후방하우징(140)과의 접속면 외부로 누설이 차단되게 하는데, 이에 따라 구성부품의 수가 증가하고 이에 따라 재료비의 증가 및 작업 공수가 늘어나는 문제가 발생하였다.In addition, as shown in FIGS. 3 and 4, the valve structure of the conventional compressor is assembled by connecting a valve plate 144 made of metal and a sealing member made of a separate gasket 170 material on both sides thereof with the valve plate 144. Or a sealing material such as an O-ring 171 is separately inserted to block the leakage to the outside of the connection surface between the cylinder bore 111 and the rear housing 140. Accordingly, the number of components increases, thereby increasing the material cost and There was a problem of increased labor.

이때 상기 디스차지밸브(43b)의 냉매의 압력으로 인한 손상 방지를 위해 디스차지 리테이너(45)를 장착하여 밸브 플레이트(44)와의 사이에서 디스차지밸브(43b)를 압박하여 디스차지밸브(43b)에 가해지는 충격을 완충하도록 되어 있다.At this time, in order to prevent damage caused by the pressure of the refrigerant in the discharge valve 43b, a discharge retainer 45 is mounted to press the discharge valve 43b between the valve plate 44 and the discharge valve 43b. It is designed to dampen the impact on the product.

이러한 밸브 구조는 리벳(46)에 의해 리벳팅 결합으로 일체화되며, 이에 따라 석션밸브(43a)와 밸브 플레이트(44)와 디스차지밸브(43b) 및 리테이너(45)가 리벳팅 결합으로 일체 형성되는 것이다.Such a valve structure is integrated into the riveting coupling by the rivet 46, whereby the suction valve 43a, the valve plate 44, the discharge valve 43b and the retainer 45 are integrally formed by the riveting coupling. will be.

본 발명은 밸브 플레이트의 실링부재를 형성하여 개스캣 또는 오링의 개재를 삭제 가능하게 함으로써 구성을 단순하게 하고 작업 공수를 줄이며 조립비용을 낮추어 작업효율을 상당히 증대시키는 효과가 있다.The present invention has the effect of forming a sealing member of the valve plate to remove the interposition of the gasket or O-ring to simplify the configuration, reduce the number of work and lower the assembly cost to significantly increase the work efficiency.

아울러 본 발명은 밸브 플레이트와 리드밸브 그리고 리테이너를 리벳팅 결합하여 일체화 함으로써 조립공정을 단순화 하여 작업효율을 증대시키는 효과가 있다. In addition, the present invention has the effect of increasing the work efficiency by simplifying the assembly process by integrating the valve plate, the reed valve and the retainer by integrating.
