SOLENOID VALVE DEVICE

PROBLEM TO BE SOLVED: To provide a solenoid valve device capable of reducing noise due to a movable core colliding against a guide member. SOLUTION: The solenoid valve 10 is equipped with a fixed core 11, the cylindrical movable core 40, a valve member 50 for opening/closing fluid passages 72 and 73 by reciprocating integrally with the movable core 40 in the axial direction of the movable core 40, coil parts 20 and 21 for attracting the movable core 40 to the fixed core 11 and moving it in the axial direction by forming a magnetic field by energization, and the guide member 33 having a guide wall 36 for guiding the movable core 40 from the inner side in the radial direction of the movable core 40 to the axial direction of the movable core 40. The solenoid valve device 10 has a space 38 formed on the inside in the radial direction of the guide wall 36. The guide wall 36 is formed to be elastically deformable, and deflects into the space 38 when pressured by the movable core 40 displaced in the radial direction. COPYRIGHT: (C)2004,JPO
