<p>An actuating means for a valve (30) that is both opened and closed with a snap-action. The bidirectional, bi-stable snap acting valve (30) has adjustable resistive forces governing the snap action of the valve (30). The bi-stable snap action mechanism (25) can be incorporated into the operation of the valving element (30) or the valving actuators (12).</p> |
