Description

압축기{Compressor}Compressor

본 발명은 압축기에 관한 것으로서, 보다 상세하게는 구동축에 일체 결합된 사판의 회전에 연동하여 피스톤이 왕복 운동하는 사판식 압축기에 관한 것이다.The present invention relates to a compressor, and more particularly, to a swash plate compressor in which the piston reciprocates in conjunction with the rotation of the swash plate integrally coupled to the drive shaft.

일반적으로 공기조화장치용 압축기는 증발기로부터 증발이 완료되어 토출된 냉매가스를 흡입하여 액화되기 쉬운 고온고압 상태의 냉매가스로 변환시켜 응축기로 토출한다. 이러한 압축기에는 경사진 사판의 회전으로 피스톤이 왕복 운동하는 사판식 압축기, 2개의 스크롤의 회전운동에 의해 압축하는 스크롤식 압축기, 회전 베인(vane)에 의해 압축하는 베인 로터리식 압축기 등 다양한 종류가 있다.In general, an air conditioner compressor sucks refrigerant gas discharged from an evaporator and is discharged into a condenser by converting the refrigerant gas into a high temperature and high pressure state which is easily liquefied. There are various kinds of such compressors, such as a swash plate type compressor in which a piston reciprocates with the rotation of an inclined swash plate, a scroll compressor compressed by a rotational motion of two scrolls, and a vane rotary compressor compressed by a rotary vane. .

피스톤의 왕복운동에 따라 냉매를 압축하는 왕복식 압축기에는 상기 사판식 압축기 외에도 크랭크식과 워블 플레이트식 등이 있으며, 상기 사판식 압축기의 경우에는 고정용량형 사판식 압축기와 가변용량형 사판식 압축기 등이 있다.The reciprocating compressor that compresses the refrigerant according to the reciprocating motion of the piston includes crank and wobble plate type, in addition to the swash plate compressor, and the swash plate compressor includes a fixed capacity swash plate compressor and a variable capacity swash plate compressor. have.

도 1에는 고정용량형 사판식 구조를 채용한 종래의 압축기가 도시되어 있다. 도시된 바와 같이, 종래의 압축기(10)는 전방 및 후방하우징(11)(12)과, 이러한 전방 및 후방하우징(11)(12)의 내측에 결합하고 내부에 사판실(13e)이 형성되며 다수의 실린더보어(13b,13d)가 형성된 실린더블록(13,13a)과, 상기 사판실(13e)에서 회 전하는 사판(15)이 경사지게 일체 결합된 구동축(14)과, 상기 사판(15)의 회전운동에 연동하여 상기 실린더보어(13b,13d) 내를 왕복 운동하는 다수의 피스톤(16)과, 상기 전방 및 후방하우징(11)(12)과 실린더블록(13,13a) 사이에 각각 개재되는 밸브유니트(17,18)를 구비한다.1 shows a conventional compressor employing a fixed displacement swash plate structure. As shown, the conventional compressor 10 is coupled to the inside of the front and rear housings 11 and 12, and the swash plate chamber 13e is formed inside the front and rear housings 11 and 12, Cylinder blocks 13 and 13a having a plurality of cylinder bores 13b and 13d formed therein, a drive shaft 14 to which the swash plate 15 rotating in the swash plate chamber 13e is inclined and integrally coupled, and the swash plate 15 A plurality of pistons 16 reciprocating in the cylinder bores 13b and 13d in association with a rotational movement, and interposed between the front and rear housings 11 and 12 and the cylinder blocks 13 and 13a, respectively. Valve units 17 and 18 are provided.

상기 전방 및 후방하우징(11)(12)에는 흡입실(11a,12a) 및 토출실(11b,12b)이 형성되어 있으며, 상기 흡입실(11a,12a)의 냉매가 피스톤(16)의 흡입행정에 의하여 상기 밸브유니트(17,18)를 통과하여 실린더보어(13b,13d)의 내부로 흡입된다. 상기 실린더보어(13b,13d)의 내부로 흡입된 냉매는 피스톤(16)의 압축행정에 의하여 상기 밸브유니트(17,18)를 통과하여 토출실(11b,12b)로 토출된다.The suction chambers 11a and 12a and the discharge chambers 11b and 12b are formed in the front and rear housings 11 and 12, and the refrigerant in the suction chambers 11a and 12a is the suction stroke of the piston 16. It is sucked into the interior of the cylinder bores 13b and 13d by passing through the valve units 17 and 18. The refrigerant sucked into the cylinder bores 13b and 13d is discharged to the discharge chambers 11b and 12b through the valve units 17 and 18 by the compression stroke of the piston 16.

한편, 상기 밸브유니트(17)(18)는 흡입리드밸브 및 토출리드밸브의 휘어짐에 의하여 냉매의 흡입 및 토출을 단속하는데, 압축기(10)가 작동하는 경우 상기 밸브유니트(17,18) 부근의 온도는 약 150℃ 이상의 고온으로 상승하게 된다.On the other hand, the valve unit (17) (18) interrupts the suction and discharge of the refrigerant by the bending of the suction lead valve and the discharge lead valve, when the compressor 10 is operating in the vicinity of the valve unit (17, 18) The temperature rises to a high temperature of about 150 ° C or more.

이때, 상기 토출리드밸브의 휘어짐을 지지하는 헤드가스켓(17a,18a)에 토출리드밸브가 달라붙을 수 있다는 문제점이 발생하게 된다. 왜냐하면, 상기 헤드가스켓(17a,18a)의 외면에는 고무코팅층이 위치하는데, 이 고무코팅층과 토출리드밸브의 가동부위가 고온상태에서 접하게 되면 서로 달라붙기 때문이다.At this time, there is a problem that the discharge lead valve may be stuck to the head gasket (17a, 18a) for supporting the bending of the discharge lead valve. This is because a rubber coating layer is located on the outer surfaces of the head gaskets 17a and 18a, because the rubber coating layer and the movable portion of the discharge lead valve are stuck to each other when they are in contact with each other at a high temperature.

토출리드밸브의 가동부위가 헤드가스켓(17a,18a)에 달라붙게 되면, 토출리드밸브가 원위치로 복귀하지 못하게 되므로 압축기(10)의 흡입행정시에 실린더보어(13b,13d)를 밀폐하지 못하게 된다, 따라서, 토출된 냉매가 흡입행정에서 다시 실린더보어(13b,13d)로 흡입되는 현상이 발생하여 압축기의 내구성 및 효율을 저하시키게 된다는 문제점이 있다.When the movable part of the discharge lead valve is stuck to the head gasket 17a, 18a, the discharge lead valve cannot be returned to its original position, and thus the cylinder bores 13b and 13d cannot be sealed during the suction stroke of the compressor 10. Therefore, there is a problem in that the discharged refrigerant is sucked back into the cylinder bores 13b and 13d in the suction stroke, thereby lowering the durability and efficiency of the compressor.

본 발명은 상술한 문제점을 해결하기 위하여 창출된 것으로, 토출리드밸브의 가동부위가 헤드가스켓에 달라붙지 않도록 하여 압축기의 내구성 및 효율을 향상시킬 수 있도록 그 구조가 개선된 압축기를 제공하는데 그 목적이 있다.SUMMARY OF THE INVENTION The present invention has been made to solve the above-mentioned problems, and an object of the present invention is to provide a compressor having an improved structure so that the movable part of the discharge lead valve does not stick to the head gasket to improve durability and efficiency of the compressor. have.

Is formed.

그리고 상기 헤드가스켓의 고착방지부에는 상기 토출리드밸브의 가동부위와 접하는 부분을 따라 홈이 형성되는 것이 바람직하다.In addition, it is preferable that grooves are formed along the contact portion of the discharge lead valve in the preventing portion of the head gasket.

그리고 상기 헤드가스켓의 고착방지부는 상기 토출리드밸브의 가동부위와 접하는 부분을 따라 고무코팅층을 제거하는 것이 바람직하다.In addition, the anti-sticking portion of the head gasket preferably removes the rubber coating layer along the contact portion of the discharge lead valve.

본 발명의 압축기에 의하면, 운전중 고온의 상태에서 토출리드밸브가 헤드가스켓에 달라붙는 것을 방지함으로써, 흡입행정시에 토출리드밸브가 밸브플레이트의 토출공을 완벽하게 밀폐할 수 있다는 장점이 있다. 따라서, 흡입부와 토출부가 연통되는 현상을 방지하여 압축기의 내구성 및 효율을 현저하게 향상시킬 수 있게 된다.According to the compressor of the present invention, it is possible to prevent the discharge lead valve from sticking to the head gasket in a high temperature state during operation, so that the discharge lead valve can completely close the discharge hole of the valve plate during the suction stroke. Accordingly, the phenomenon in which the suction part and the discharge part communicate with each other can be prevented, thereby making it possible to remarkably improve the durability and efficiency of the compressor.

도 3을 참조하면, 본 발명의 바람직한 실시예에 따른 압축기의 밸브유니트(170,180)는, 상기 실린더보어(130a,131a)에 대응하여 흡입공(172a,182a) 및 토출공(172b,182b)이 형성된 밸브플레이트(172,182)와, 상기 밸브플레이트(172,182)의 외측에 위치하여 상기 토출공(172b,182b)을 개폐하는 토출리드밸브(173,183)를 포함한다.Referring to FIG. 3, the valve units 170 and 180 of the compressor according to the preferred embodiment of the present invention have suction holes 172a and 182a and discharge holes 172b and 182b corresponding to the cylinder bores 130a and 131a. The valve plates 172 and 182 formed thereon and discharge lead valves 173 and 183 positioned outside the valve plates 172 and 182 to open and close the discharge holes 172b and 182b.

상기 흡입공(172a,182a)은 밸브플레이트(172,182)의 내측에 위치한 흡입리드밸브(174,184)에 의하여 개폐된다. 상기 흡입리드밸브(174,184)와 실린더블록(130,131)의 사이에는 석션가스켓(175,185)이 위치하여 흡입리드밸브(174,184)와 실린더블록(130,131)을 밀폐한다.The suction holes 172a and 182a are opened and closed by suction suction valves 174 and 184 positioned inside the valve plates 172 and 182. Suction gaskets 175 and 185 are positioned between the suction lead valves 174 and 184 and the cylinder blocks 130 and 131 to seal the suction lead valves 174 and 184 and the cylinder blocks 130 and 131.

한편, 토출리드밸브(173)(183)의 외측에는 헤드가스켓(171,181)이 위치하여 토출리드밸브(173,183)의 휘어짐을 지지하며, 이 헤드가스켓(171,181)의 외면에는 고무코팅층이 형성되어 밸브플레이트(172,182)와 전방 및 후방 하우징(110)(120)을 밀폐한다.Meanwhile, head gaskets 171 and 181 are positioned outside the discharge lead valves 173 and 183 to support the bending of the discharge lead valves 173 and 183, and a rubber coating layer is formed on the outer surface of the head gaskets 171 and 181. Seals 172 and 182 and front and rear housings 110 and 120.

상기 토출리드밸브(173,183)는 피스톤(160)의 압축행정에 의하여, 실린더보어(130a,131a)의 압력이 높아지면 휘어지면서 밸브플레이트(172,182)의 토출공(172a,182a)을 개방하게 된다.The discharge lead valves 173 and 183 are bent when the pressure of the cylinder bores 130a and 131a is increased by the compression stroke of the piston 160 to open the discharge holes 172a and 182a of the valve plates 172 and 182.

이 토출공(172b,182b)을 통하여 냉매가 토출되며, 냉매가 토출된 후 피스톤(160)의 흡입행정에 의하여 상기 실린더보어(130a,131a) 내부의 압력이 낮아지면 토출리드밸브(173,183)가 원위치로 되돌아가면서, 밸브플레이트(172,182)의 토출공(172b,182b)을 밀폐하게 된다.When the refrigerant is discharged through the discharge holes 172b and 182b and the pressure inside the cylinder bores 130a and 131a is lowered by the suction stroke of the piston 160 after the refrigerant is discharged, the discharge lead valves 173 and 183 are discharged. While returning to the original position, the discharge holes 172b and 182b of the valve plates 172 and 182 are sealed.

그리고, 상기 석션가스켓(175,185)은 밸브플레이트(172,182)와 실린더블록(130,131)의 사이에 위치하여, 밸브플레이트(172,182)와 실린더블록(130,131)의 사이를 밀폐한다. 이 석션가스켓(175,185)도 상기 헤드가스켓(171,181)과 마찬가지로 외면에 고무코팅층이 형성된다.The suction gaskets 175 and 185 are disposed between the valve plates 172 and 182 and the cylinder blocks 130 and 131 to seal between the valve plates 172 and 182 and the cylinder blocks 130 and 131. Similar to the head gaskets 171 and 181, the suction gaskets 175 and 185 are provided with a rubber coating layer.

상기 헤드가스켓(171,181)은 휘어진 토출리드밸브(173,183)를 지지하여 토출리드밸브(173,183)가 과도하게 휘어지는 것을 방지한다. 여기서, 냉매가 토출되는 부위의 온도는 약 150℃ 이상의 고온으로 상승 될 수 있으며, 헤드가스켓(171,181) 의 고무코팅층에 토출리드밸브(173,183)의 가동부위가 달라붙게 된다는 문제점이 발생한다.The head gaskets 171 and 181 support the curved discharge lead valves 173 and 183 to prevent the discharge lead valves 173 and 183 from being excessively bent. The temperature at which the refrigerant is discharged may rise to a high temperature of about 150 ° C. or more, and a problem occurs that the movable portions of the discharge lead valves 173 and 183 adhere to the rubber coating layers of the head gaskets 171 and 181.

본 발명의 압축기(100)는 이와 같은 문제점을 해결하기 위하여, 헤드가스켓(171,181)과 토출리드밸브(173,183)의 가동부위가 접하는 부분에 고착방지부(171a,181a)가 형성된다.In the compressor 100 of the present invention, in order to solve such a problem, the anti-sticking portions 171a and 181a are formed at portions where the moving parts of the head gaskets 171 and 181 and the discharge lead valves 173 and 183 are in contact with each other.

도 4는 도 3에 도시된 헤드가스켓 및 토출리드밸브의 결합상태를 도시한 도면이고, 도 5는 도 4의 Ⅴ-Ⅴ선에 따른 단면도이다.도 4 및 도 5를 참조하면, 헤드가스켓(171,181)에 고착방지부(171a,181a)가 형성된 모습을 볼 수 있다.4 is a view illustrating a coupling state of the head gasket and the discharge lead valve shown in FIG. 3, and FIG. 5 is a cross-sectional view taken along the line VV of FIG. 4. Referring to FIGS. 4 and 5, the head gasket ( 171 and 181 may be seen that the anti-seizure parts 171a and 181a are formed.

상기 헤드가스켓(171,181)의 고착방지부(171a,181a)에는 상기 토출리드밸브(173,183)의 가동부위와 접하는 부분을 따라 홈이 형성되도록 하여, 토출리드밸브(173,183)의 가동부위가 헤드가스켓(171,181)과 접하지 않도록 하는 것이다.In the anti-sticking portions 171a and 181a of the head gaskets 171 and 181, grooves are formed along the contact portion of the discharge lead valves 173 and 183 so that the movable portions of the discharge lead valves 173 and 183 are head gaskets. 171,181).

그리고 토출리드밸브(173,183)가 헤드가스켓(171,181)에 달라붙게 되는 원인인 고무코팅층을 제거함으로써 토출리드밸브(173,183)가 헤드가스켓(171,181)에 달라붙는 현상을 방지하게 된다. 따라서, 피스톤(160)의 흡입행정시에 토출리드밸브(173,183)가 토출공(172a,182a)을 완벽하게 밀폐할 수 있다는 장점이 있다.In addition, the discharge lead valves 173 and 183 may be prevented from sticking to the head gaskets 171 and 181 by removing the rubber coating layer which causes the discharge lead valves 173 and 183 to stick to the head gaskets 171 and 181. Therefore, the discharge lead valves 173 and 183 may completely seal the discharge holes 172a and 182a at the suction stroke of the piston 160.

이와 같이, 토출리드밸브(173,183)의 가동부위가 헤드가스켓(171,181)과 접하지 않으므로, 토출리드밸브(173,183)의 가동부위가 헤드가스켓(171,181)에 달라붙는 현상을 더욱 완벽하게 방지할 수 있다.As such, since the movable portions of the discharge lead valves 173 and 183 are not in contact with the head gaskets 171 and 181, the movable portions of the discharge lead valves 173 and 183 may be more completely prevented from sticking to the head gaskets 171 and 181. .
