SOLENOID VALVE UNIT

PROBLEM TO BE SOLVED: To provide a solenoid valve unit which can be easily assembled by supporting solenoids by a housing, so that the solenoids can be appropriately put on columnar members containing parts of the valve operating sections. SOLUTION: Sleeves 20 containing part of the valve operating section of solenoid valves and composed of columnar members are erected on a valve housing 10. Then, sub-assembled solenoid units 40 each of which is composed of a cylindrical coil 44, first and second yokes 41 and 42 which are positioned on both sides of the coil 44 in the axial direction and joined to the coil 44, and a wave washer 45 which is interposed between the yoke 41 and the coil 44 are constituted. The coils 44 are fixed to solenoid housings 30, and the yokes 41 and 42 are supported so that the yokes 41 and 42 can be moved relatively to the coils 44. When the solenoid housings 30 are assembled with the valve housing 10, the coils 44 can be easily put on the sleeves 20.
