Claims (1)

  1. 압력 공급원으로부터 밸브 본 체내에 도입된 압력 유체의 유압 실린더에 대한 흐름 방향을, 스풀절환작동에 의해 제어하도록 구성된 방향제어밸브에 있어서,
    상기 유압 실린더의 한쪽 유실과 스풀을 연결하는 통로에 그 통로를 개폐하는 포켓식 피스톤을 주체로 하는 유량제어기구를 설치하고, 상기 스풀이 유압 실린더의 다른 쪽 유실에 압력 유체를 공급하는 절환작동이 된때 상기 피스톤에 대하여 상기 압력 공급원으로 부터의 파일럿 압력을 개방 방향으로 작용시키는 한편, 유압 실린더의 상기 한쪽 유실에 작용하는 부하에 대응하는 배출측 압력 유체의 배압을 폐쇄방향으로 작용시킴으로써 유압 실린더의 한쪽 유실로부터의 압력 유체배출 유량을 제어하도록 구성된 것을 특징으로 하는 유량제어기구를 구비한 방향제어밸브.
