Abstract
A change valve for an air compressor is combined with the vent tube of an air compressor, including a connector, a valve base, a valve body, an anti-leak gasket, a sleeve and a button. The valve base has at least two connect tubes, with a guide tube connected to each of the connect tubes. The button can be turned to rotate the valve base together with the valve body, so the vent hole of the valve body can be aligned to the air hole of either of the two connect tubes. If the air compressor operates, compresses air may flow in the valve body via the air hole into the guide tube via the vent hole of the connect tubes, and finally into an object. In this way, interchanging the position of the vent hole of the valve body enables the change valve connected to objects having different air valves.
