Abstract

A coupler for refrigerant injection is provided to clamp automatically by operation of a switch after being inserted into an injection port, cut off a refrigerant pipe valve automatically when clamping is released, and release clamping automatically after injection is completed. A clamp piston(40) receives compressed air and moves forward by a spring pressure. A refrigerant injection front end valve moves balls(100) inserted into a gate circumference through the forward movement of the clamp piston in a shaft center direction by a front end inclined plane of the clamp piston, and opens a valve stem(50) by an injection port inclined plane. The refrigerant injection front end valve is opened by the valve stem for performing vacuum and refrigerant injection. After the refrigerant injection, compressed air applied to the clamp piston is discharged to deviate pushing positions of the balls so that a valve spring pushes up an adaptor and a valve is closed by sealing-up of the clamp piston and an O-ring.

본 발명은 냉동시스템상에 냉매를 주입하기 위한 것으로서, 보다 상세하게는 주입구에 삽입 후 에어의 힘으로 자동 클램핑하는 것을 특징으로 하는 냉매 주입용 커플러에 관한 것이다. The present invention relates to a refrigerant injection coupler for injecting a refrigerant on a refrigerating system, and more particularly, to automatically clamp with the force of air after insertion into the injection port.

일반적으로 도 1에는 이러한 구조의 냉방장치에 냉매인 에어컨 가스를 주입하기 위한 종래의 커플러가 단면으로 도시되어 있다. 이 커플러를 이용하여 에어컨 가스를 주입하기 위해서는 먼저 가압 스프링(5)을 압축하면서 슬리이브(4)를 화살표(P)방향으로 당긴 다음 가상선으로 도시한 차량 측 가스 주입파이프(6)를 클램프 클램프 피스톤(clamp piston)(40) 본체(1) 내에 삽입한다. 상기 클램프 클램프 피스톤(clamp piston)(40) 본체(1)에 끼워져 있는 볼(3)은 가스 주입파이프(6)의 외주에 형성된 걸림홈(7)에 걸리게 된다. 이후 슬리이브(2)를 놓게 되면, 가압 스프링(5)에 저장되어 있던 탄성력에 의해 슬리이브(2)는 원래의 위치로 복귀하면서 볼(3)을 가압하여 주입파이프(6)의 결합상태를 견고하게 유지하도록 이루어진 것이 었다. In general, Figure 1 is a cross-sectional view of a conventional coupler for injecting the air-conditioning gas refrigerant as a cooling device of such a structure. In order to inject the air-conditioning gas using this coupler, the pressure spring 5 is first compressed, and the sleeve 4 is pulled in the direction of the arrow P, and then the vehicle side gas injection pipe 6 shown as a virtual line is clamped and clamped. The piston (40) is inserted into the body (1). The ball 3 fitted into the clamp piston 40 main body 1 is caught by the locking groove 7 formed on the outer circumference of the gas injection pipe 6. Then, when the sleeve 2 is released, the sleeve 2 is returned to its original position by the elastic force stored in the pressure spring 5 to press the ball 3 to maintain the coupling state of the injection pipe 6. It was designed to remain solid.
