Abstract

See full text

A solenoid valve includes a coil (102) and an armature (80) adapted to be attracted by the coil are housed in a body (70). A valve seat (74) on which a valve part (82) formed integral with the armature is also disposed in the body. A high-pressure path (76) is connected to the valve seat. The high-pressure path is disconnected from a low-pressure path when the valve part rests on the valve seat, and communicates with the low-pressure path when the valve part moves off the valve seat. The valve part moves onto and away from the valve seat when the armature moves as the coil is electrically energized and de-energized. The energizing force of a coil spring 104 urges the valve part to rest on the valve seat. A through-hole (86) is formed in that portion of the valve part which faces the high-pressure path. A sealing member (106, 110) is fitted into the through-hole and is held in place by the body.
