Claims

[Scope of utility model registration request]

It has a piston that is movably installed in a cylinder formed in the valve body, and moves in response to increases and decreases in pilot pressure acting on one side of the piston, thereby moving the valve body attached to the piston to the valve body. In a pilot type solenoid valve that controls communication between an inlet port and an outlet port by engaging or disengaging with a valve seat provided within the piston, an annular groove is formed on the outer periphery of the piston, and a is provided with a plurality of piston rings each having an annular groove formed on the outer periphery, and an inner ring is provided inside each piston ring, and the sum of the thickness of the piston ring in the q and direction and the wall thickness of the inner ring in the radial direction is A pilot operated solenoid valve characterized by a depth greater than the depth of the annular groove of the piston.
