Description

파이롯트 밸브
본 내용은 요부공개 건이므로 전문내용을 수록하지 않았음
제1도는 레버의 전후 요동 방향에 평행하는 면의 단면도이고, 제2도는 레버의 좌우 요동방향에 평행하는 면의 단면도이다. 제3도는 이 구체예에 관한 유압 회로를 표시하는 블록선도.

Claims (1)

  1. 레버의 전후 좌우 방향의 요동에 따라 밸브 본체에 형성된 복수조의 쌍을 이루는 출구 폿트로서 압유를 출력하는 파이롯트 밸브에 있어서, 상기 밸브 본체가 1조의 쌍을 이루는 출구폿트를 1조의 쌍을 이루는 주출구 폿트에 순방향으로 연통하는 제1위치와 역방향으로 연통하는 제2위치 사이로 이동하도록 설치된 절환스푸울을 구비하고, 상기 절환스푸울을 다른 1조의 쌍을 이루는 출구폿트의 압유로서 제1위치, 제2위치로 절환하도록 구성한 것을 특징으로 하는 파이롯트 밸브.
    ※ 참고사항 : 최초출원 내용에 의하여 공개하는 것임.
