Abstract : The patent relates to a high-pressure gas-filling apparatus and method for filling gas containers such as lamps to a positive pressure of several atmospheres to minimize waste of supply gas. Empty lamp bodies are attached to a filling manifold and the filling apparatus is evacuated to a desired pressure range before filling occurs. After the lamps have been filled and sealed, control valves are closed to trap unused supply gas in the system. The trapped gas is then liquified and collected in a freezeout chamber by applying cooling to the freezeout chamber. When cooling is discontinued, the liquified gas in the chamber revaporizes and when sufficient pressure builds up, the gas reenters the high-pressure supply side of the apparatus for reuse.
