ABSTRACT:
In an air valve for an inflatable object, a valve body is connected sealingly to the inflatable object and defines an air passage in fluid communication with an interior of the inflatable object. A movable member is disposed within the air passage and is adapted to connect with a connection head of an inflation device. A rotary member is rotatable to bring the movable member to one of an open position and a sealing position to permit or stop air flow through the air passage.
