Abstract
A solenoid valve has a valve body with first and second passages; a coil wound around a coil bobbin; a stator with a third passage; a plunger having a through hole therein; a flux return device; and a spring. When the coil is energized, the plunger is attracted toward the stator such that the plunger closes the third passage, and connects the first passage with the second passage through the through hole in the coil bobbin. When the coil is not energized, the plunger moves away from the stator such that the plunger closes the first passage, and connects the second passage with the third passage. A resilient gasket between the stator and the flux return device reduces vibration from direct contact between the plunger and the stator, being transmitted to the flux return device, thereby reducing vibration and noise.
