Abstract

본 발명은 자동차 엔진의 실린더헤드 커버에 장착되는 PCV밸브의 이중구조에 관한 것으로, 2차 밸브피스톤 내부에 스프링 특성이 2차 밸브스프링과 상이한 1차 밸브스프링으로 작동되는 1차 밸브피스톤을 내장하여 블로우 바이 가스의 누출량을 2단으로 조정하는 구조를 가지며 고 RPM에서 블로우 바이 가스의 역류를 방지하고 밴틸레이션 홀로는 항시 새로운 공기가 공급되게 하며 실린더 헤드 커버에 취부되는 케이스 부분에 텝을 가져서 종래와 같이 고무 플러그의 탄성으로 밀봉되지 않으므로 밀봉성이 완벽하다.The present invention relates to a dual structure of a PCV valve mounted on a cylinder head cover of an automobile engine, in which a primary valve piston having a spring characteristic different from that of the secondary valve spring is operated by a primary valve spring It has a structure that adjusts the amount of blow-by gas to two stages, prevents reverse flow of blow-by gas at high RPM, always supplies new air to the vortillation hole, and has a tap in the case part attached to the cylinder head cover, As it is not sealed with the elasticity of the rubber plug, the sealing property is perfect.
