发明名称 Dual snap action for valves
摘要 An actuating means for a valve that is both opened and closed with a snap-action. The bidirectional, bi-stable snap acting valve has adjustable resistive forces governing the snap action of the valve. The bi-stable snap action mechanism can be incorporated into the operation of the valving element or the valving actuators.
