Abstract

본원의 유압구동장치는 서보실린더(13)와 서보피스톤(11)의 사이에 이 피스톤을 에워싸는 축방향으로 이동가능한 라이너를 배설한다.The hydraulic drive apparatus of the present application arranges an axially movable liner surrounding the piston between the servo cylinder 13 and the servo piston 11.

라이너는 서보실린더(13)에서 압력매체라인(27)의 접속부(21)와, 릴리프라인(24)의 접속부(23)와 연통되는 개구(61,61′,62,62′)를 포함한다. 라이너(60)는 출구밸브의 실링부와 반대측 단부에서 커버(60′)에 의해 기밀하게 시일된다. 상기 커버(60′)와 서보실린더의 상단커버(13′)의 사이에 압력매체로 충전된 챔버(68)가 배설되며, 이 챔버는 이 챔버의 방향으로 닫히는 비귀환밸브(69)를 통해 서보실린더내의 압력챔버(65), 및 벤팅라인의 방향으로 닫히는 비귀환밸브(70)를 통해 벤팅라인(26)과 연통된다. 압력챔버(65)는 릴리프라인(24)으 접속부(23)와 항상 접속된다.The liner includes a connection portion 21 of the pressure medium line 27 and openings 61, 61 ′, 62, 62 ′ in communication with the connection portion 23 of the relief line 24 in the servo cylinder 13. The liner 60 is hermetically sealed by a cover 60 'at an end opposite to the sealing portion of the outlet valve. A chamber 68 filled with a pressure medium is disposed between the cover 60 'and the top cover 13' of the servo cylinder, and the chamber is operated by a non-return valve 69 which closes in the direction of the chamber. It communicates with the venting line 26 through the pressure chamber 65 in the cylinder, and the non-return valve 70 which closes in the direction of the venting line. The pressure chamber 65 is always connected to the connecting portion 23 by the relief line 24.
