Claims (1)

  1. 축방향 중앙부에서 2개의 수푸울편으로 분할된 스푸울과, 이들 스푸울편을 축방향 안쪽으로 힘을 가하여 안쪽끝 위치에 복귀시키는 복귀스프링과, 한쪽 스푸울편의 축방향 바깥쪽 끝에 한쪽의 급배통로의 내압을 유도하는 제1통로와, 다른쪽의 스푸울편의 축방향 바깥쪽 끝에 다른쪽의 급배통로의 내압을 유도하는 제2통로와, 급배 통로의 내압중 고압쪽의 내압을 선택하여 상기 스푸울편 간에 형성된 압력실에 유도하는 압력선택수단을 갖춘 카운터 밸런스 밸브에 있어서, 상기 압력실내의 유체에 의하여 양 스푸울편이 함께 안쪽끝 위치에서 축방향 바깥쪽으로 각각 이동하고 있을 때, 급배통로 끼리를 연통하는 연통로를 설치한 것을 특징으로 하는 카운터 밸런스 밸브.
