Abstract:
1. A solenoid operated valve assembly, comprising: a solenoid can; a valve body connected to the solenoid can; a pole piece connected to the solenoid can operating to transfer a magnetic flux; a homogenous valve member/armature slidably disposed in the valve body and movable from a valve closed position to a valve open position in the presence of the magnetic flux; a bushing portion of the valve body engaged with the solenoid can having a predetermined length establishing a non-zero clearance gap between the pole piece and the valve member/armature in either an energized or a de-energized position of the valve member/armature; and a solenoid bushing retained in the solenoid can by the bushing portion, the solenoid bushing having a bushing sleeve, the valve member/armature received in and in sliding contact with the bushing sleeve; a coil received in the solenoid can adapted when energized to provide the magnetic flux to the pole piece to move the valve member/armature from the de-energized position toward the pole piece to the energized position; and a valve element having a first side adapted to contact the bushing portion in the energized position of the valve member/armature.
