FLUID VALVE FLUID SYSTEM CONSTRUCTION MACHINERY AND CONTROL METHOD
본 발명의 독립 미터링 밸브(2)는, 밸브 보디(3)와, 미터 아웃 스풀(15)을 구비한다. 밸브 보디(3)는, 작동유에 의해 구동되는 유압 실린더(113)에 마련된 각 포트(Rp, Hp) 중 어느 것에 접속되는 각 배출 포트(D1, D2)와, 각 배출 유로(135, 136)에 접속되는 각 탱크 포트(T1, T2)를 갖는다. 미터 아웃 스풀(15)은, 헤드 포트(Hp)에만, 제2 탱크 포트(T2)에만, 그리고 헤드 포트(Hp) 및 제2 탱크 포트(T2)의 양쪽 중 어느 것에, 로드 포트(Rp)를 연통시킨다.
The invention provides a fluid valve, a fluid system, a construction machine, and a control method. An independent regulating valve (2) is provided with a valve body (3) and an outlet regulating spool (15). The valve body (3) has: discharge ports (D1), (D2) connected to any of ports (Rp), (Hp) provided to a hydraulic cylinder (113) driven by hydraulic oil; and tank ports (T1), (T2) that are connected to discharge flow paths (135), (136). The outlet adjustment spool (15) causes the rod port (Rp) to communicate only with the cap port (Hp), or causes the rod port (Rp) to communicate only with the (2)-th tank port (T2), or causes the rod port (Rp) to communicate with both the cap port (Hp) and the (2)-th tank port (T2).
