Abstract

본 발명의 목적은 차체의 내부 하방부분을 오일고임으로 하는 작업차량에 있어서, 유압작동수단용의 제어밸브의 오일드레인포트로부터 유로중으로 공기가 들어가는 것을 방지하는데 있다. 오버플로구(91a)로부터의 오일고임(49)으로서 오일 오버플로에 의하여 오일고임의 유면(OL)면보다 높은 유면(OLb)을 유지하는 오일고임챔버(91)를 설치하고, 제어밸브(68)의 오일드레인포트(68T2)를 챔버유면보다 하방레벨에서 상기 챔버에 연통시켰다.
상기 챔버는 제어밸브의 밸브케이스를 차체하우징(1)에 고정지지시켜 상기 케이스내에 서로 접합되는 두 케이스 부재(56, 57) 사이에서 형성되고, 오버플로구를 차체하우징내로 직접 개구시키는 것이 바람직하다.
