Claims (1)
- 작동체로 향하는 유압 경로를 가변시키는 스풀유닛과, 상기 작동체가 일방향으로 끝까지 움직여서 내압이 증가하면 그 압력이 상기 스풀유닛에 작용되게 하여 유압 경로를 바꿔줌으로써 상기 작동체가 타방향으로 움직이게 하는 압력제어부 및, 상기 압력제어부에서 상기 스풀유닛의 한 쪽으로 유체를 공급하여 이동시킬 때 다른 쪽에 있던 유체가 빠져나갈 수 있게 해주는 배출수단을 포함하는 자기압력 방향전환밸브에 있어서,상기 배출수단은,유체가 빠져나가는 경로를 형성하는 리턴유로 및,상기 리턴유로 상에 설치된 체크밸브를 구비하는 것을 특징으로 하는 자기압력 방향전환밸브.
