ABSTRACT:
A compact device for sealingly storing, and subsequently delivering to the interior of a tire, a predetermined charge quantity of a tire leak sealant liquid includes a hollow liquid storage and transfer member, having an inlet fitting and an outlet fitting, within which the sealant liquid is disposed. When the hollow member is operatively interconnected between a pressurized air source and the tire's valve stem, pressurized air sequentially forces the entire sealant liquid charge volume into the tire and then flows into the tire through the storage and transfer member. Accordingly, the device may be utilized to repair and fully inflate a flat tire. A check valve structure incorporated in the device prevents fluid backflow through the storage and transfer member. The device may also be used to force other treatment liquids, such as a tire conditioner liquid, into the tire. In an alternate embodiment of the device, the storage and transfer member is filled with a refrigerant circuit treatment liquid and may be interconnected between a source of pressurized refrigerant and a refrigerant circuit fill valve to recharge the circuit and force the treatment liquid thereinto.
