Abstract: Provided is an electromagnetic valve capable of preventing damage due to wear while preventing an increase in weight of a valve element. The electromagnetic valve includes a solenoid having a plunger movably supported along an axial direction, a flow path member having a fluid passage flow path and a valve element housing portion, and a valve element disposed in the valve element housing portion and movable along the axial direction together with the plunger. The valve element includes a body part, a valve part that opens and closes the fluid passage flow path as the plunger moves, and a pin in a rod-like shape that passes through the body part along the axial direction. The body part is provided with at least one opening that opens in a direction orthogonal to the axial direction and through which the pin is exposed.

Abstract: An electromagnetic valve includes: a solenoid, including a bobbin, a plunger, and a coil that moves the plunger; and a valve mechanism, including a flow path member that includes a first flow path, a second flow path, a relay part and a valve body housing, and a valve body that is inserted into the valve body housing, movably supported along an axial direction together with the plunger, and switches between passage and blockage between the first and the second flow paths. The valve body includes: a protrusion provided protruding radially outward from an outer periphery of the valve body and guided by an inner wall surface of the valve body housing when the valve body moves; a body made of resin; and a pin made of metal, provided at a center of the body along the axial direction and penetrating the body.

Abstract: An electromagnetic valve includes a solenoid having a plunger; 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 has a valve part in a ring shape which opens and closes the relay flow path; and a spring disposed in the valve body housing and urging the valve body along the axial direction, wherein the valve body further includes a guide part guided on an inner wall surface of the valve body housing when the valve body moves together with the plunger and a small diameter part provided between the guide part and the valve part, wherein the small diameter part faces the first flow path.

Abstract: An electromagnetic valve includes a solenoid and a valve mechanism. The valve mechanism includes: a flow path member, including a valve body housing, a first flow path and a second flow path; and a valve body, inserted into the valve body housing, reciprocatably supported along an axial direction, and switching between passage and blockage between a first port of the first flow path and a second port of the second flow path. The valve body includes protrusions guided by an inner wall surface of the valve body housing when the valve body moves. The protrusions include a first protrusion and a second protrusion respectively located at both ends of the valve body on one end side and the other end side in the axial direction, and the first protrusion moves in a region closer to one side in the axial direction than the second port.
