Abstract

See full text

The solenoid valve (10) has a poppet valve (41) which is operated to move between a position to close a port and a position to open the port. A fixed iron core (50) having a supporting leg (52) and a driving leg (51) is installed in a valve housing (11), and a movable iron core (60) which drives the poppet valve (41) is disposed between a valve driving member (42) and the fixed iron core (50). An arcuate sliding contact surface (61) is provided on one end portion of the movable iron core (60), and a sliding-abutting surface (62) which abuts on the sliding contact surface (61) is provided on a leading end portion of the supporting leg (52). When a coil (56) is de-energized, the sliding-contacting surface (61) is pressed onto the sliding-abutting surface (62) by a flat spring (70), with an abutting portion of the valve driving member (42) serving as a fulcrum of a tensile force applied to the movable iron core (60).
