Abstract: A fitting for a liquid gas bottle with a gas consumer connection piece, with a gas inlet opening on the underside, with a gas conducting connection between the gas inlet opening and the gas consumer connection piece, with a rotary handle, which can be turned into an open position and into a closed position, wherein in the open position gas can flow from the gas inlet opening to the gas consumer connection piece and in the closed position no gas can flow from the gas inlet opening to the gas consumer connection piece, with a closable opening on the upper side of the fitting, with a gas conducting connection which connects the closable opening on the upper side with an opening at the underside in such a way that refilling a connected gas bottle with gas through the underside and through the closable opening is possible, characterized in that the edge of the closable opening is part of the rotary handle.

Abstract: A filling station comprises a filling device for an automated filling of a gas bottle inserted in the filling station and a filling device for refueling a motor vehicle, wherein the filling device for an automated filling of a gas bottle inserted in the filling station is arranged adjacent to the filling device for refueling a motor vehicle.

Abstract: 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.

Abstract: The filling station according to the invention enables an automated refilling of a gas bottle by an end-user. This comprises an insertion device, which enables an end-user to insert an emptied gas bottle into the filling station. The filling station comprises a closing device for closing the filling station after the insertion of the gas bottle such that a removal of the gas bottle subsequent to the closing is not possible. The end-user may not remove the gas bottle in a closed state. Furthermore, the filling station comprises a filling device for an automated filling of an into the filling station inserted emptied gas bottle subsequent to the closing. A filling may thus only take place, if the filling station is closed and in consequence the gas bottle cannot be removed. There is a gas testing device for an automated gas leakage test after a refilling of an inserted gas bottle. With it, the tightness of a once again filled gas bottle is tested.
