Claims (2)
- 출구밸브의 실링부와 반대측 단부에서 서보실린더내에서 가이드되는 서보피스톤에 접속되고, 밸브개방방향으로 유압매체가 엔진의 속도에 따라 공급되고, 압력매체원으로부터 서보실린더내의 압력챔버로 압력매체라인을 통해 공급되고, 압력매체라인과는 별개로 릴리프라인 및 벤팅라인이 접속되는 앙복동내연기관의 출구밸브의 유압구동장치에 있어서, 서보실린더와 서보피스톤의 사이에 이 피스톤을 에워싸는 축방향으로 이동가능한 라이너를 배설하고, 이 라이너는 서보실린더에서 압력매체라인의 접속부와, 릴리프라인의 접속부와 연통되는 최소한 하나의 개구를 포함하며, 라이너는 출구밸브의 실링부와 반대측 단부에서 커버에 의해 기밀하게 시일되고, 상기 커버와 서보실린더의 상단 커버의 사이에 압력매체로 충전된 챔버가 배설되며, 이 챔버는 이 챔버의 방향으로 닫히는 비귀환밸브를 통해 압력챔버, 및 벤팅라인의 방향으로 닫히는 비귀환밸브를 통해 벤팅라인과 연통되고, 압력챔버는 서보실린더에서 릴리프라인의 접속부와 항상 접속되는 것을 특징으로 하는 왕복동내연기관의 출구밸브의 유압구동장치.
- 제1항에 있어서, 커버는 라이너와 분리될 수 있도록 설치되는 것을 특징으로 하는 왕복동내연기관의 출구밸브의 유압구동장치.※ 참고사항 : 최초출원 내용에 의하여 공개하는 것임.
