摘要： A stop valve for closing a nozzle in a fluid passage comprising: a valve shaft movable in the axial direction relative to the nozzle; a solenoid attached to an end of the shaft for moving the shaft in the axial direction; an auxiliary valve consisting of a secondary valve body disposed around the shaft and a supporting part extending in the axial direction of the valve shaft and engaged with a part of the valve shaft through a spring for carrying the secondary valve body at one end and a spring-engaging portion at the other end and for moving together with the valve shaft in the axial direction; a main valve body disposed around the valve shaft between the spring-engaging portion and the secondary valve body and formed with a central aperture to be opened or closed by the secondary valve body, the main valve body being pressed against the secondary valve body by a contracted spring disposed between the spring-engaging portion of the supporting part of the auxiliary valve and the main valve body so that the main valve body can move together with the secondary valve body in the axial direction of the valve body to close or open the nozzle; and resilient means energized to adequately press the secondary valve body in the axial direction away from the nozzle when the main valve body is in the closed position.
