US Patent 7168428 Apparatus for connecting air bottles

An air transfer apparatus for transferring air from a replenishment air cylinder to another air cylinder is provided. The air transfer apparatus comprises a first valve adapted to engage a replenishment air cylinder and a second valve having quick connect fittings adapted to engage one or more air cylinder fittings mounted on one or more air cylinders. A high pressure hose provides gaseous communication between the first valve and the second valve. A regulator is positioned between the first valve and the second valve. The regulator is adapted to control the air pressure in the high pressure hose between the first valve and the second valve to match the air pressure needed in one of the one or more air cylinders.
