キツク式電磁弁。[Scope of Claim for Utility Model Registration] A movable partition member that liquid-tightly partitions between the inlet side of the main valve hole and the back chamber is provided with a main valve body that opens and closes the main valve hole, and A pilot-type solenoid valve that is driven by an excitation coil and has a bleed hole that communicates with the chamber, and a pilot valve hole that is larger in diameter than the bleed hole and that communicates between the back chamber and the outlet side of the main valve hole. A movable pilot valve body is installed in the installation chamber at the tip of the plunger so that its outer periphery can slide in the axial direction of the plunger, and a communication hole is provided in the plunger to communicate the back of the movable pilot valve body installation chamber with the back chamber. and the movable pilot valve body has a valve hole with a smaller diameter than the pilot valve hole opened in the axial direction of the plunger, and has spring means for biasing the plunger toward the movable partition panel. A two-stage pilot-operated solenoid valve featuring:
