INTEGRATED AIR VALVE

Abstract: an integrated air valve includes a hollow shell formed with a valve installation space, two air holes respectively an air inlet hole and an exhaust hole communicated to the space, and two support members; two lever members; and two shape memory alloy members. the lever member uses one of the support members as a fulcrum. the lever member includes an actuating end, and an action end capable of closing the air hole. a part of the shape memory alloy members are hung on the actuating ends of the lever members, and capable of driving the lever members based on an energized state. one of the lever members determines conduction of the air inlet hole to achieve air intake, the other lever member determines whether the exhaust hole communicates to an external space to achieve exhaust, and the lever members determine whether the integrated air valve enters air pressure maintenance.
