ABSTRACT:
A solenoid operated valve is provided that comprises an inlet, an outlet, a valve seat in the flow path between the inlet and the outlet, and a valve member slidably mounted for movement in a direction aligned with but perpendicular to the plane of the valve seat, and a lever having one end in connection with the valve member and a pivotal end that is operable for moving the valve member between its closed and open positions. The solenoid operated valve further comprises a solenoid actuated member having spaced apart first and second surfaces for engaging the pivotal end of the lever to move the valve member between its closed and open position, and a spring for resiliently biasing the solenoid actuated member so that the first surface engages the pivotal end of the lever to move the valve member to a closed position against the valve seat when the solenoid is not energized.
