Kind Code:
A1
Abstract:
Provided is a solenoid valve that can increase the operability of a movable iron core. A solenoid valve 1 comprises: a movable iron core 4 that can move in the axial direction; a solenoid molded body 31 that is provided to the outer periphery of the movable iron core 4; a solenoid case 30 that accommodates the movable iron core 4 and the solenoid molded body 31; and a fixed iron core 38 that is arranged inside the solenoid molded body 31 and causes magnetic force to be generated between the fixed iron core and the movable iron core 4 as a result of electrical conduction to a coil 34 of the solenoid molded body 31. The solenoid valve 1 is horizontally attached to an attachment member. The fixed iron core 38 is provided with a high magnetoresistance region 38f that suppresses the formation of magnetic flux downward in a vertical direction.
