Abstract

유량제어밸브는 제1포트와 제2포트를 가진 하우징과 이 하우징내에 장착된 스풀을 구비하고 있다. 유체압력을 스풀의 양단에서 제거하는 제1유체챔버와 제2유체챔버는 오리피스가 형성된 유체통로를 통하여 서로 연통하고 있다. 스풀이 이동할 때, 스풀의 양단에서의 압력차에 의해서 발생된 스풀에 대한 추력은 가압수단에 의해서 발생된 가압력과 평형을 이룬다. 유량제어밸브는 시일부재와 함께 탄성재질로 이루어진 환형의 시일부재를 구비하고 있다. 스풀의 외주상의 랜드부의 에지가 환형의 시일과 접촉할 때, 제1포트는 제2유체챔버로부터 완전하게 차단된다. 따라서, 누출은 밸브부가 폐쇄될 때 제로가 된다.
