WIPO Patent Application WO/2020/184031
Kind Code:
A1
Abstract:
This fluid control valve (5) comprises: a valve part support member (58) to which a valve part (57) is mounted; and a plunger (55) that drives the valve part support member (58) in the axial direction. The fluid control valve (5) comprises a yoke (56) that is fixedly installed and that forms a magnetic circuit with the plunger (55) when a current is passed therethrough. The fluid control valve (5) comprises parallel parts respectively provided to the plunger (55) and the yoke (56) in a manner such that a magnetic flux passes between the plunger (55) and the yoke (56), the parallel parts being formed so as to run along one another in a cross-sectional shape. In a closed-valve state, an upstream-side annular part (550) contacts an upstream-side first annular part (560). Further, in the closed-valve state, the plunger (55) contacts the valve part support member (58) and supports the valve part support member (58) in the axial direction.
