일반적으로 알려진 바와 같이 자동차용 공기조화장치를 구성하는 압축기는 증발기로부터 열교환된 냉매를 흡입한 후 피스톤의 직선 왕복 운동에 의하여 압축하여 응축기로 토출하는 것으로서, 상기 압축기는 자동차의 풀리를 통하여 전달되는 엔진의 동력을 전자클러치의 단속 작용에 의하여 선택적으로 전달받아 작동하는 것이다.As is generally known, a compressor constituting an air conditioner for a vehicle is a suction of a heat exchanged refrigerant from an evaporator, compressed by a linear reciprocating motion of a piston, and discharged to a condenser. The compressor is an engine delivered through a pulley of an automobile. It operates by selectively receiving the power of electric clutch by the intermittent action of the electronic clutch.

상기한 압축기는 압축방식 및 구조에 따라 왕복식 및 회전식으로 구분되고, 상기 왕복식인 경우에는 크랭크식, 사판식, 워블플레이트식 등이 있으며, 상기 회전식인 경우에는 베인로터리식 및 스크롤식 등이 있고, 상기 압축기 중에는 압축 용적을 변화시킬 수 있는 가변용량형 타입도 있다.The compressor is divided into a reciprocating type and a rotary type according to the compression method and structure, and the reciprocating type includes a crank type, a swash plate type, a wobble plate type, and the rotary type type including a vane rotary type and a scroll type type. Among the compressors, there is also a variable displacement type that can change the compression volume.

도 2 내지 도 6은 본 발명에 따른 밸브유니트를 나타낸 도면이다.2 to 6 are views showing the valve unit according to the present invention.

도시한 바와 같이 본 발명에 따른 밸브유니트는 냉매흡입구(미도시)와 냉매토출구(11)가 형성된 밸브플레이트(10)와, 상기 냉매토출구(11) 상에 형성된 안착부(12)에 수용되며 피스톤의 압축행정시에 상기 냉매토출구(11)를 개방시키는 판상의 토출리드(20)와, 상기 냉매토출구(11)에 대응되는 위치에 토출리드 유도홈(31)이 형성되고, 상기 안착부(12)에 수용되어진 토출리드(20)의 양단부가 면접촉되도록 밀착되며, 상기 토출리드(20)의 작동 영역을 제한하도록 이루어진 밸브리테이너(30)를 포함하는 것이다.As shown in the drawing, the valve unit includes a valve plate 10 having a refrigerant inlet (not shown) and a refrigerant outlet 11, and a seating portion 12 formed on the refrigerant outlet 11, and having a piston. And a discharge lead guide groove 31 formed at a position corresponding to the refrigerant discharge port 11 and a plate-shaped discharge lead 20 which opens the refrigerant discharge port 11 at the time of compression stroke. Both ends of the discharge lead 20 accommodated in the) is in close contact with the surface contact, and includes a valve retainer 30 configured to limit the operating area of the discharge lead 20.

또한, 상기 밸브리테이너(30)는 각 위치별로 형성된 냉매토출구(11)를 안정적으로 커버함과 아울러 토출리드(20)를 압박할 수 있도록 냉매토출구(11) 위치에 대응되게 한개의 개체로 형성되는 것이며, 상기 밸브리테이너(30)와 밸브플레이트(10)가 체결볼트에 의해서 고정되게 되면 토출리드(20)는 안착부(12)에 밀착된 상태가 되는 것이다.In addition, the valve retainer 30 is formed as a single object to cover the refrigerant discharge port 11 formed in each position and to correspond to the refrigerant discharge port 11 position to press the discharge lead 20 stably. When the valve retainer 30 and the valve plate 10 are fixed by the fastening bolt, the discharge lead 20 is in close contact with the seating part 12.

그리고, 상기 토출리드(20)가 냉매의 압축 압력에 의해서 작동되게 되면, 상기 토출리드(20)는 토출리드 유도홈(31) 측으로 탄력 팽창되고, 상기 토출리드 유도홈(31) 측으로 토출리드(20)가 오픈되면 토출리드(20)의 양측면을 통하여 냉매가 토출되는 것이며, 상기 각 토출리드(20)를 통과한 냉매는 밸브리테이너(30)의 원주 방향으로 토출되는 것이다.When the discharge lead 20 is operated by the compression pressure of the refrigerant, the discharge lead 20 is elastically expanded toward the discharge lead guide groove 31 and the discharge lead toward the discharge lead guide groove 31. When the opening 20 is opened, the refrigerant is discharged through both side surfaces of the discharge lead 20, and the refrigerant passing through the discharge leads 20 is discharged in the circumferential direction of the valve retainer 30.

After the elastic expansion to the (31) side, if the pressure of the refrigerant is lowered below a certain level, it is to return to the original state.

그리고 상기 토출리드(20)가 오픈 되면 토출리드(20)의 양측면으로 냉매가 토출되는 것이며, 상기 토출리드(20)의 양측면으로 냉매가 토출됨에 따라 냉매토출구(11)를 통과한 냉매의 맥동 압력이 급격하게 낮아지는 것이고, 상기 토출리드(20)의 작동시에 밸브리테이너(30)에 의해 토출리드(20)의 양단이 고정되기 때문에 토출리드(20)의 운동시 움직임이 자연스럽고 타격 소음 또한 발생치 않는 것이다.When the discharge lead 20 is opened, the refrigerant is discharged to both sides of the discharge lead 20, and the pulsation pressure of the refrigerant passing through the refrigerant discharge port 11 as the refrigerant is discharged to both sides of the discharge lead 20. Since the discharge lead 20 is fixed at both ends of the discharge lead 20 by the valve retainer 30 when the discharge lead 20 is operated, the movement of the discharge lead 20 is natural and the impact noise is also reduced. It doesn't happen.

It is done.

이상과 같이 본 발명은 밸브플레이트에 냉매토출구를 방사상으로 각각 형성함과 아울러 출구측에 안착부를 형성하고, 상기 냉매토출구 대향지점에 밸브리테이너를 위치시킴과 아울러 상기 밸브리테이너에 토출리드 유도홈을 형성하여 토출리드가 위치되도록 함으로써 냉매토출시에 토출리드의 과도한 움직임을 방지함과 아울러 타격 소음이 저감되게 되는 것이다.As described above, the present invention forms radial discharge outlets on the valve plate, forms a seating portion at an outlet side, positions the valve retainer at an opposite point of the refrigerant discharge outlet, and forms a discharge lead guide groove in the valve retainer. Thus, the discharge lead is positioned to prevent excessive movement of the discharge lead when the refrigerant is discharged and to reduce the blow noise.

그리고 토출리드를 토출리드 유도홈에 배치함으로써 토출리드 오픈시에 토출리드의 양측면을 통하여 냉매가 원활하게 토출되는 것이고, 상기 냉매가 토출될 때 냉매토출구를 통과한 후부터 급격하게 토출리드의 양측면으로 이동됨에 따라 맥동압이 현저하게 낮아지는 것이다.By discharging the discharge lead into the discharge lead guide groove, the refrigerant is smoothly discharged through both sides of the discharge lead when the discharge lead is opened. As the pulsation pressure decreases significantly.
