<p>This solenoid valve is provided with a housing, a plunger, a spring, and a solenoid. The housing is provided with: a cylindrical guide member which aids movement of the plunger in the axial direction; a sheet member which is fitted to the guide member, and which has valve holes; a fixed core which is disposed facing an end of the guide member so as to be separated therefrom by a prescribed amount in the axial direction; and a sleeve which is fluid-tightly connected respectively to the outer periphery of an end of the fixed core and the outer periphery of the end of the guide member, and which integrally connects the fixed core and the guide member. A communication hole and a channel are provided in the plunger. The communication hole passes through the plunger in the axial direction, and communicates a passage (communicating an inflow port and an outflow port) at one end and a spring accommodation part at another end. The channel allows the communication between the communication hole, and a gap formed inside the sleeve between the end of the fixed core and the end of the guide member. As a result, when operating fluid flows from the inflow port to the outflow port, said operating fluid flows into the communication hole via the channel, and flows from the passage to the housing exterior, thereby enabling air in the solenoid valve to be discharged to the exterior.</p> |
