Abstract

본 발명에 의하여, 동일하지 아니한 피스톤속도에 의하여 작동실린더를 유압식으로 슬라이드 밸브 제어함에 있어서, 피스톤을 작동시키는 유압매체의 체적유량을 그때 그때의 피스톤속도에 적합하게 조절하여 작동하고, 피스톤의 운동방향을 예비제어되은 방향밸브에 의하여 조정할수 있으며, 역동밸브(S3)를 예비제어밸브(A)에 의하여 유압식으로 예비제어하고, 이러한 예비제어밸브를 작동실린더(1)용 제어임펄스에 의하여 조절할 수 있고, 예비제어밸브(A)로부터 역동밸브(S3)까지 이르는 예비제어로 (11,12)사이에 유압에 의하여 예비제어되는 제어밸브(B)를 설치하며, 유압매체의 두갈래 체적유량중 하나가 이러한 제어밸브(B)를 통하여 흐르고 제어밸브(B)의 각 위치에 따라 피스톤 속도가 조절 된다.

Description
