    • A 3-way hydraulic valve (10) comprising a body formed with an inlet port (14) for connecting to a pressurized supply line, a first outlet port (16) for connecting to an outlet line and being in flow communication with the inlet port, a gate (20) intermediate the inlet port and the first outlet port, dividing the body into an inlet chamber and an outlet chamber, the body further comprises a second outlet (18) extending from the outlet chamber (26), and a control chamber fitted with a deformable diaphragm (34) sealingly engageable with the gate so as to prevent flow between the inlet port and the first outlet port, and a sealing port (50) associated with the second outlet and comprising a sealing member (60) linearly displaceable between a closed and an open position. The sealing member is attached to the diaphragm by a linking element (64) having at least two degrees of freedom, whereby when the diaphragm engages the gate, the sealing port is opened and when the diaphragm disengages from the gate the sealing port is closed and disengagement of the diaphragm from the gate entails closing of the sealing port by the sealing member.
    • 一种三通液压阀(10),包括形成有用于连接到加压供应管线的入口(14)的主体,用于连接到出口管线并与入口端口流动连通的第一出口(16) ,所述入口端口和所述第一出口端口之间的门(20)将所述主体分成入口室和出口室,所述主体还包括从所述出口室(26)延伸的第二出口(18) 室配有可与隔板密封接合的可变形隔膜(34),以防止入口和第一出口之间的流动,以及与第二出口相关联的密封端口(50),其包括密封构件(60) 可在闭合位置和打开位置之间移动。 密封构件通过具有至少两个自由度的连接元件(64)附接到隔膜,由此当隔膜接合门时,密封口打开,当隔膜与门隔开时,密封口关闭, 隔膜与门的脱离接合需要通过密封构件封闭密封口。
