Scope of claim for Utility Model Registration - A reversible solenoid valve with a primary joint, a secondary joint, and an electromagnetic mechanism connected to the valve body, and a check valve built into the piston that opens and closes the valve based on fluid pressure. At the same time, a through hole 3110 is provided from the bottom of the check valve toward the outer circumference of the piston, and a through hole that is opened and closed by the electromagnetic mechanism on the secondary joint side is provided in the valve body on the secondary joint side, and a through hole is provided that faces a part of the inner wall of the valve body. A reversible solenoid valve characterized in that a partition wall is formed by forming a flow path from the through hole to an upper part of a piston.
