A system provides regulated delivery of a high-pressure gas. A first flow path, coupled to a high-pressure gas source, is in fluid communication with a chamber. A flow restrictor, disposed in the first flow path, slows the gas traveling along the first flow path to the chamber. A second flow path, coupled to the high-pressure gas source, is in fluid communication with the chamber. A third flow path connects the chamber to a pressure regulator. A valve, disposed in the second flow path, seals the second flow path when gas pressure at the source exceeds gas pressure in the chamber. The valve opens the second flow path when the gas pressure at the source is balanced with the gas pressure in the chamber allowing the high-pressure gas to flow to the regulator via the third flow path.

It is object of the invention to reduce the technical expenditure for refilling of gas bottles. For solving the problem, a claimed fitting comprises a gas tap for gas withdrawal and an opening for refilling a liquid gas bottle. The opening for refilling a liquid gas bottle can be connected, in particular by opening a valve, in a gas-conducting manner to a hose-shaped or tubular line of the fitting, which can extent into a liquid gas bottle by at least 300 mm, preferably at least 400 mm, if the fitting is connected with such a gas bottle. Hereby, it can achieved that the line extents into the liquefied part of the gas, which especially enables a very fast emptying though pumping. Emptying is necessary when a refilled gas bottle proves to be untight. A speed advantage is thereby achieved. Basically, there is an opening at the bottom side of the fitting adjacent to the hose-shaped or tubular line. The bottom side is the side, which adjoins the liquid gas bottle or respectively is arranged entirely in the bottle or in a bottle neck when the fitting is connected to a liquid gas bottle. This opening at the bottom side can be connected to the gas tap in a gas-conducting manner, specifically typically by rotating a corresponding rotary handle. The hose-shaped or tubular line protrudes relative to the opening, specifically in particular by at least by 200 mm, particularly preferred by at least 300 mm. A method concerns the refilling of a liquid gas bottle comprising the claimed fitting.
