摘要： A resetable shut off valve includes a body (10) having an inlet (12) and an outlet (14). The inlet and outlet are connected in the valve body through a fluid passage which includes an opening (26). A movable plunger assembly (42) includes a seal disc (56) sized for blocking the opening. The plunger assembly is biased towards a position blocking the opening by a compression spring (57). A u-shaped wire spring (66) includes a foot portion (70) which engages a recess (46) in the plunger assembly to hold the assembly disposed from the opening. The foot portion of the wire spring abuts a first surface (36) in the body. The wire spring is attached at the end opposed of the foot portion to a movable pressure plate (58) which abuts a diaphragm (80). When fluid pressure is introduced to a second chamber of the valve (78) above the diaphragm, the wire spring is pushed against the first surface, deforms and disengages the recess in the plunger assembly. The plunger assembly moves downward until the seal disc blocks the opening closing the valve. The valve is reset to the open condition by manually moving a pushrod (88), which moves the plunger assembly upward until it again engages the wire spring.
