SOLENOID VALVE

A solenoid valve has a valve body with first and second ports. A bobbin is mounted to the valve body. A winding is wound on the bobbin. A stator is fitted to one end of a hole through the bobbin and defines a third port therein. A plunger is slidably fitted to the hole and movable between a normal p...

Beschreibung
Zusammenfassung:	A solenoid valve has a valve body with first and second ports. A bobbin is mounted to the valve body. A winding is wound on the bobbin. A stator is fitted to one end of a hole through the bobbin and defines a third port therein. A plunger is slidably fitted to the hole and movable between a normal position and an energized position. Two plugs are installed at respective ends of the plunger and arranged to selectively close the first and third ports. A flux return device is fixed to the stator and the bobbin. A spring returns the plunger from the energized position, where the plunger closes the third port and the first and second ports communicate with each other via the hole in the bobbin, to the normal position, where the plunger closes the first port and the second and third ports communicate with each.
