ABSTRACT:
A water filled tire filling device including a barrel portion with an axial bore therethrough. One end of the bore has an enlarged inner diameter with an air vent aperture in the wall thereof, and the inner wall threaded adjacent the open end, with the thread being suitable for attachment to a conventional tire valve member. A valve stem tube is inserted into the bore and secured therein with an end of the tube projecting beyond the end of the enlarged diameter bore portion a distance to be in proximity to the valve needle member of the tire valve when the filling device is connected to the tire valve. For larger volume and/or faster fills the needle valve assembly can be removed prior to insertion of the tube. If the needle valve assembly is not removed, actuation of the valve needle member is accomplished by the inner diameter of the tube being sufficient to pass into proximity with the needle member or sufficient to pass about the needle member and seat against the surrounding valve seat. Liquid entering through the tube depresses the valve needle member of the tire valve member. The other end of the barrel member is provided with a shoulder and a water hose coupling fitting, whereupon attachment of the fitting to a water hose, and attachement of the internally threaded portion of the enlarged diameter bore portion enables filling of the tire with liquid while providing an annular air vent about the periphery of the tube with the air escaping through the vent aperture during the filling operation.
