The problem addressed by the invention is to reduce the technical complexity for refilling gas cylinders. In order to solve the problem, a fitting as claimed comprises a gas tap for gas withdrawal and an opening for refilling a liquid gas cylinder. The opening for a refilling of a liquid gas cylinder can be connected, in particular, in a gas-conducting manner to a hose-like or tubular line of the fitting, which can extend into a liquid gas cylinder by at least 300 mm, preferably at least 400 mm, if the fitting is connected to such a gas cylinder. In this way, the line can extend into the liquefied part of the gas, which, above all, enables very fast emptying by means of pumping. Emptying is imperative if a refilled gas cylinder proves to be leaky. A speed advantage is achieved in this way. In principle, there is an opening on the underside of the fitting adjacent to the hose-like or tubular line. The underside is the side which adjoins the liquid gas cylinder or is located fully in the cylinder or in the cylinder neck when the fitting is connected to the liquid gas cylinder. Said opening on the underside can be connected to the gas tap in a gas-conducting manner, and generally by rotating a corresponding rotary handle. The hose-like or tubular line protrudes relative to said opening, preferably by at least 200 mm, particularly preferably by at least 300 mm. A method relates to the refilling of a liquid gas cylinder comprising the claimed fitting. |
