Claims

[Scope of utility model registration request]

The solenoid part includes a valve part that switches a fluid passage and a solenoid part that drives a valve body in the valve part, and the solenoid part surrounds the outside of an excitation coil with a magnetic frame forming a magnetic path, and the dF! A fixed iron core is fitted and fixed in the cylindrical hole b, and a movable iron core that is attracted to the fixed iron core and drives the valve body when the coil is energized is slidably inserted in the axial direction, and the movable iron core An auxiliary iron that is attracted to the end face of the magnetic frame when the coil is energized is installed at the outer end of the coil so that it can be separated from the movable iron core, and the stroke of the auxiliary iron is made smaller than the stroke of the movable iron 6. Features a solenoid valve.
