Abstract:
1. A solenoid operated valve comprising: an inlet; an outlet; a valve seat in the flow path between the inlet and outlet; a valve element for sealingly engaging the valve seat; a moveable member coupled with the valve element, the movable member being movable for opening and closing the valve; a stationary core; a resilient dampening member that is independent from and not disposed within a portion of with the stationary core; a spring having a first end engaging the resilient dampening member, and a second end biasing the movable member away from the resilient dampening member to a closed position; a solenoid that is energized by a direct current voltage which causes the movable member to move from the closed position to an open position against the resilient dampening member associated with the stationary core, wherein the resilient dampening member prevents direct contact between the moveable member and the stationary core.
