Abstract

이 발명에서는 발명자 이전에 신규한 밸브를 발명하여 출원공개하였다.(특개소 61-228178호).
이 벨브는 적은 힘으로 비교적 압력이 높은 액체에 대하여 밸브의 개폐를 용이하게 할 수 있고 개폐시에 완충할 수가 있었다.
그러나, 이 밸브는 개폐시 완충이 불충분한 것이었다.
본 발명의 목적은 계폐도 충분하게 완충 할 수 있고, 미속개방, 미속폐쇄를 할수 있는 밸브를 제공하는 것이다.
축구멍, 옆구멍 및 밸브시트를 까지는 밸브실의 길이방향의 도중에 오리피스를 가지는 스페이서를 설치하고, 상기 밸브시트쪽에 밸브실을, 그 반대쪽에 후실을 형성하고, 상기 전실에 제1스프링을 통하여 주밸브를 수용하고, 상기 후실에 대개 용기형상하고 역류방지 밸브에 붙은 통공을 가지는 부밸브를 제2스프링을 통하여 수용하고, 상기 후실과 상기 옆구멍 및 축구멍을 각각 역류방지 밸브를 통하여 연이어 통하고, 상기 후실과 기름탱크를 트레인 통로에 연이어 통하고, 이 드레인 통로 개폐벨브를 설치하였다.
