Claims

[Scope of utility model registration request]

A solenoid housing made of a magnetic material and a spool housing are connected, a fitting hole is formed in the solenoid housing, a plunger made of a magnetic material is fitted into the fitting hole in a movable manner, and a plunger made of a magnetic material is fitted into the fitting hole in the same direction as the fitting hole. A sliding hole is formed in the sliding hole, a spool made of a magnetic material and operated by the plunger is slidably inserted into the sliding hole, and a spring biasing the spool toward the plunger is installed between the spool and the spool housing. A yoke is formed in the solenoid housing, a solenoid that generates a magnetic force that attracts the plunger toward the yoke is disposed around the solenoid housing, and a cover made of a magnetic material that covers the solenoid is attached to the solenoid housing. In the solenoid valve, a bearing is disposed in a part of the fitting hole, a shaft is guided to the bearing so as to be movable in the same direction as the spool, the plunger is attached to the shaft, and the cover is immersed in the liquid. 1. A solenoid valve, characterized in that a part of the cover immersed in the liquid is provided with filters communicating with the outside in chambers on both sides of the fitting hole divided by the plunger.
