Patent ID: 8151824

Claim:
A solenoid operated valve assembly, comprising: a solenoid can; a valve body connected to the solenoid can having an inlet port and a fixed first valve seat; a pole piece to transfer a magnetic flux connected to the solenoid can; a valve member/armature having a first end positioned proximate to the pole piece and a piston defining a second end, the valve member/armature created of a homogenous single element of a magnetically effected material throughout including the first and second ends; a resilient material valve element positioned between the first and second ends and connected to the valve member/armature, the valve member/armature slidably disposed in the valve body and movable from a valve closed position having the valve element contacting the first valve seat toward the pole piece to reach a valve open position in the presence of the magnetic flux; a biasing member partially received in each of a pole piece cavity and a member cavity of the valve member/armature, acting to continuously bias the valve member/armature away from the pole piece and toward the valve closed position; a first end wall of the second end in continuous fluid communication with a pressurized fluid at the inlet port in both the valve open and closed positions; and a second valve seat movably positioned with respect to the fixed first valve seat, a first side of the valve element contacting the fixed first valve seat in the valve closed position and a second side of the valve element contacting the second valve seat in the valve open position.
