Claims

[Scope of utility model registration request]

(1) A casing in which an inlet and an outlet are formed, a core fixed to the casing and around which a solenoid is wound;
It consists of a movable iron piece that is formed into a bottomed cylindrical shape by a bottom plate and a peripheral wall and is activated by excitation and demagnetization of the solenoid, and a valve body that is attached to the movable iron piece and connects and shuts off the inflow port and the outflow port. A solenoid valve, characterized in that a tapered portion is formed on the inner peripheral surface of the peripheral wall of the movable iron piece, and a fluid passageway is formed in the movable iron piece to allow fluid to flow between the front and back in the operating direction.

(2) The solenoid valve according to claim (1), wherein the fluid passage is formed in the bottom plate.

(3) The solenoid valve according to claim (1), wherein the fluid passage is formed on the outer peripheral surface of the peripheral wall.

(4) The solenoid valve according to item (1) of the utility model registration claim, wherein the fluid passage is formed by removing the magnetic path of the movable iron piece.
