Description

유압제어밸브
본 내용은 요부공개 건이므로 전문내용을 수록하지 않았음
제1도는 중립상태의 주요부 횡단면도, 제2도는 밸브제가 우측으로 조금 회전한 상태의 주요부 횡단면도, 제3도는 밸브제가 우측으로 크게 회전한 상태의 횡단면도.

Claims (3)

  1. 기름도입로 및 기름도출로를 구비하여, 홈부와 랜드부가 소정방향으로 교대로 형성되어 있는 케이싱과, 케이싱에 대해 상기 방향으로 상대적으로 이동할 수 있도록 부착되며, 귀환유로를 구비하고, 홈부와 랜드부가 상기 이동방향으로 교대로 형성되어 있는 밸브체로 이루어지며, 중립상태에 있어서, 케이싱과 밸브체의 흡부와 랜드부가 서로 대향하고, 기름도입로에서 공급된 기름이 귀환유로에 흘러, 중립상태에서 케이싱에 대해 밸브체가 이동했을때, 케이싱과 밸브체의 랜드부에 의해 기름도입로와 귀환유로와의 사이가 차단되어 기름도입로에서 공급된 기름이 기름도출에 흐르게 개끔 되어 있는 유압재어밸브에 있어서, 케이싱 또는 밸브체의 랜드부에, 중립상태로 부터의 케이싱에 대한 밸브체의 이동량이 소정치보다 커졌을때에 기름도입로에서 공급된 기름을 귀환유로에 흐르게 하는 요부가 형성되어 있는 것을 특징으로 하는 유압제어밸브.
  2. 제1항에 있어서, 케이싱이 원통형상의 것이고, 그 내부면에 축선방향으로 뻗는 홈와 랜드부가 형성되고, 밸브체가 케이싱의 내측에 축선을 중심으로 회전할 수 있도록 끼워진 원주형상의 것이며, 그 외주면에 축선방향으로 뻗는 홈부와 랜드부가 형성되어 있는 것을 특징으로 하는 유압제어밸브.
  3. 제1항에 있어서, 케이싱이 원통형상의 것이고, 그 내부면에 환상의 홈부와 랜드부가 형성되고, 밸브 체가 케이싱 내측에 축선방향이고 이동할 수 있도록 끼워진 원주형상의 것이고, 그 외주면에 환상의 홈부와 랜드부가 형성되어 있는 것을 특징으로 하는 유압제어밸브.
