More Information
Summary:A solenoid valve is provided that includes an inlet, an outlet, a valve seat in the flow path between the inlet and the outlet, a stationary core, and a moveable member for moving between an open position and a closed position against the valve seat. A resilient dampening member is disposed between the moveable member and the stationary core, and is independent from both the stationary core and the moveable member. A spring biases the resilient dampening member against the stationary core and the moveable member away from the stationary core to a closed position. Upon energizing a solenoid with a direct current voltage, the moveable member moves from the closed position towards the stationary member to an open position against the resilient dampening member. The resilient dampening member dampens the impact between the moveable member and the stationary core to reduce the noise associated with energizing the solenoid.
