Claims

[Scope of utility model registration request]

A solenoid includes a stator and a coil wound around the stator, and the solenoid is fitted into an opening on the side facing the stator, and is reciprocated within the opening by an electric current applied to the coil. A movable element that
It consists of a valve base that is opened and closed by the movable element, and has a hole in the axial direction of the movable element, and a check valve that restricts the flow of fluid in one direction at the end of the hole. Features a solenoid valve.
