도면중 종래와 동일한 부분에 대하여는 동일한 부호를 부여하였다.In the drawings, the same reference numerals are given to the same parts as in the prior art.

도면중 미설명 부호인 4A 및 4B 및 4C는 토출커버 및 토출밸브 및 밸브스프링, P는 압축공간이다.In the drawings, reference numerals 4A, 4B, and 4C denote discharge caps and discharge valves and valve springs, and P denotes a compression space.

상기와 같은 본 발명 흡입밸브 조립체의 작용 효과는 다음과 같다.Effects of the present invention, such as the suction valve assembly is as follows.

즉, 전동기구부(미도시)의 가동자가 피스톤(3)과 함께 직선으로 왕복운동을 하고, 이와 함께 피스톤(3)이 실린더(2)의 내부에서 직선으로 왕복운동을 하면서 그 실린더(2)의 압축공간(P)에 압력차를 발생시켜 냉매가스를 압축공간(P)으로 흡입하여 압축하였다가 토출하는 일련의 과정을 반복한다.That is, the mover of the electric mechanism part (not shown) reciprocates linearly with the piston 3, and together with the piston 3 reciprocates linearly inside the cylinder 2, The pressure difference is generated in the compression space P, and a series of processes of inhaling, compressing, and discharging the refrigerant gas into the compression space P are repeated.

이 과정에서 흡입밸브 조립체(100)는 피스톤(3)의 후진시 흡입유로(3a)와 흡입통구(3b)를 통해 흡입되는 냉매가스와 피스톤(3)의 전진시 압축공간(P)에서 압축되는 냉매가스에 피스톤(3)의 선단면에 착탈하게 되는데, 이때 피스톤(3)의 선단면이 고르게 가공되지 못하면 흡입밸브(110)가 받는 충격이 불균일하여 상대적으로 많은 충격을 받는 부위부터 깨져 결국 흡입밸브(110) 전체가 파손될 우려가 있는 것이나, 도 5에서와 같이 피스톤(30)의 선단면과 흡입밸브(110) 사이에 양면이 고른 밸브시트(120)를 더 구비하는 경우에는 흡입밸브(110)가 닫힐 때 밸브시트(120)의 고른 면에 접촉하므로 흡입밸브(110)의 파손을 미연에 방지할 수 있다.In this process, the suction valve assembly 100 is compressed in the compression gas P when the piston 3 is moved forward and refrigerant gas sucked through the suction passage 3a and the suction port 3b when the piston 3 moves backward. The refrigerant gas is attached to and detached from the front end surface of the piston (3). If the front end surface of the piston (3) is not evenly processed, the shock received by the suction valve (110) is uneven and breaks from a relatively large impact area. If the entire valve 110 may be damaged, or if the valve seat 120 is further provided between the front end surface of the piston 30 and the suction valve 110 as shown in FIG. 5, the suction valve 110 may be provided. When () is closed because it contacts the even surface of the valve seat 120 can be prevented in advance to damage the intake valve (110).

여기서, 밸브시트(120)는 피스톤(3)의 전체를 후가공하여 드릴 가공 등으로발생하는 버(burr)를 용이하게 제거할 수 있어 흡입밸브(110)와의 접촉면을 고르게 유지할 수 있다.Here, the valve seat 120 can easily remove the burr generated by drilling the whole by post-processing the entire piston (3) can maintain the contact surface with the suction valve 110 evenly.

본 발명에 의한 흡입밸브 조립체는, 피스톤과 흡입밸브 사이에 그 흡입밸브와 동일한 재질로 고른 면을 가지는 밸브시트를 부가함으로써, 흡입밸브의 개폐시 그 흡입밸브가 가공잔해물인 버(burr) 등에 의해 파손되는 것을 미연에 방지하여 흡입밸브의 신뢰성을 높일 수 있다.In the suction valve assembly according to the present invention, by adding a valve seat having an even surface between the piston and the suction valve of the same material as the suction valve, when the suction valve is opened and closed by the burr, etc. It is possible to prevent damage in advance, thereby increasing the reliability of the suction valve.
