Claims

[Scope of utility model registration request]

A sliding hole is formed in the valve body, a guide member is screwed onto one end of the sliding hole, and a valve seat member is provided inside the guide member with a relief passage through which pressure fluid is introduced. A direction in which a needle valve for opening and closing the relief passage is brought into contact with the seat member, a spool made of a magnetic material is slidably inserted into the sliding hole, and a gap is widened between the spool and the needle valve. A solenoid coil is wound around the outer periphery of the valve body, and a control current applied to the solenoid coil causes the spool to overcome the spring and be attracted. . A solenoid valve configured to control the opening degree of the relief passage, characterized in that a filter for removing foreign matter in oil is installed in a gap between the spool and the guide member in the sliding hole.
