A solenoid valve characterized in that the valve is provided with a check valve for regulation.

Claims

[Scope of utility model registration request]

A housing having a fluid chamber formed therein as a passage for fluid flowing from a suction side passage to a discharge side passage for a controlled fluid, a valve seat provided inside the housing, and a valve seat that approaches and separates from the valve seat. A valve for adjusting the flow of fluid, a movable core fixed to the valve, a rod fixed to the movable core, and a valve provided corresponding to the movable core and housing the rod so as to be able to reciprocate. a core for reciprocating the movable core by an electromagnetic action caused by a current flowing through a coil; and a pipe for slidably housing the movable core therein and guiding the reciprocating motion of the valve; In the electromagnetic valve provided with a communication hole that communicates a pressure chamber between the pressure chamber and the inside of the valve and the fluid chamber, the valve includes a check valve that regulates the flow of fluid from the pressure chamber side to the fluid chamber side. A solenoid valve characterized by:
