Abstract: An electromagnetic valve includes: a solenoid having a plunger movably supported along an axis O1 direction; a flow path member having a fluid passage flow path and a valve element housing portion; and a valve element in a columnar shape that is disposed in the valve element housing portion, is movable along the axis O1 direction together with the plunger, and can switch between an open state and a closed state. The flow path member has an abutment portion that abuts on the valve element in the valve element housing portion, and a biasing member that biases the valve element. The valve element has an enlarged-diameter portion on the radially outer side. The enlarged-diameter portion has an opposing surface portion opposing the abutment portion at least in the axis O1 direction. The opposing surface portion is in contact with the abutment portion in the open state.

Abstract: An electromagnetic valve includes a solenoid having a plunger; a flow path member including a fluid passage flow path having a first flow path, a second flow path, and a relay flow path which is disposed between the first flow path and the second flow path and which connects the first flow path and the second flow path, and a cylindrical space; a valve body movably disposed in the cylindrical space; and a spring which is disposed concentrically with the valve body on an outer peripheral side of the valve body in the cylindrical space and urges the valve body.

Abstract: An electromagnetic valve includes a solenoid having a bobbin, a plunger and a coil; a flow path member having a first flow path, a second flow path, a relay flow path and a valve body housing; a valve body movably disposed in the valve body housing; and a spring disposed in the valve body housing and urging the valve body, wherein the valve body further includes a plurality of guide parts which are provided at different positions along the axial direction and which are guided on an inner wall surface of the valve body housing, and a taper part which is provided between the plurality of guide parts and whose outer diameter decreases toward the one side in the axial direction.
