WIPO Patent Application WO/2016/027503
Kind Code:
A1
Abstract:
This solenoid valve (10) has a poppet valve (41) that moves between a position to close a port and a position to open the port. A fixed core (50) having a supporting leg (52) and a drive leg (51) is installed in a valve housing (11), and a moving core (60) for driving the poppet valve (41) is disposed between a valve drive member (42) and the fixed core (50). An arcuate slide contact surface (61) is provided at one end of the moving core (60), and a slide abutment surface (62) abutting on the slide contact surface (61) is provided at the leading end of the supporting leg (52). During the non-energization of a coil (56), the slide contact surface (61) is pressed against the slide abutment surface (62) by a plate spring (70), with an abutment portion of the valve drive member (42) as the fulcrum of a tensile force applied to the moving core (60).
