[Scope of Claim for Utility Model Registration] A movable partition member that has a main valve body that opens and closes the main valve hole and partitions the back chamber and the inlet side is built into the valve chamber, and the movable partition member includes the following: The pilot valve is opened and closed by a pilot valve body driven by a driving means, and has a pilot valve hole that communicates the back chamber with the outlet side of the main valve hole, and communicates the back chamber with the inlet side of the main valve hole. A pilot type solenoid valve having a bleed hole with a flow rate lower than that of the hole, wherein a plurality of filter holes smaller than the bleed hole are opened on the inlet side surface of the movable partition member,
Each filter hole communicates with one bleed hole, and the bleed hole has at least one bend in its path to form a non-linear flow path, so that the flow of liquid passing through the bleed hole is A pilot type solenoid valve characterized in that the flow resistance of the pilot valve hole is increased so that the flow rate of the bleed hole is smaller than that of the pilot valve hole, and the diameter of the pilot valve hole is approximately the same as or smaller than the diameter of the bleed hole.
