PROBLEM TO BE SOLVED: To provide a solenoid valve capable of securing the smooth operation of an actuator by preventing foreign matter from accumulating in an air gap between a yoke, a core, and a plunger. SOLUTION: This solenoid valve comprises a solenoid 3 axially sliding the plunger 83 in a plunger chamber 7 by the core 82 magnetized by supplying power to a coil and a valve body 92 axially sliding, in a spool chamber 85a, a spool 84 axially moving in synchronism with the plunger 83 and allowing communication passages 91a to 91d formed in the spool 84 to communicate with ports 95a to 95b to flow hydraulic oil therethrough. A diaphragm 1 absorbing a volumetric change in the plunger chamber 7 caused by the movement of the plunger 83 is installed in the solenoid 3. COPYRIGHT: (C)2004,JPO&NCIPI
