A method for filling tanks with pressurized gas via a filling station comprising several storage containers and a fluid circuit for transferring the gas from the containers to the tanks, the circuit comprising a first end to which the containers are linked in parallel and a second end provided with a transfer line intended to be connected to the tank(s) to be filled, the circuit comprising, arranged in series between the first end and the second end, a first isolation valve, a flow or pressure regulation member, and a second isolation valve, the method comprising filling a first tank, characterized in that, on completion of the filling of the first tank and before filling a second tank, the first and second isolation valves are closed to trap a supply of pressurized gas in the circuit between said two valves and in that the supply of gas is used to refill at least one of the containers.

Process and device for filling tanks

Device for feeding fuel gas to an application (), the device comprising at least one fuel gas bottle () furnished with a tap (), and a bleed-off apparatus () comprising an electronic logic unit () and a bleed-off outlet () selectively connectable to the tap (), the bleed-off outlet () being linked () fluidically to an application () receiving the fuel gas originating from the bottle (), the tap () comprising an electronic manometer () for measuring the pressure in the bottle (), the electronic manometer () being devoid of battery and comprising an inductive member () for wirelessly transmitting to the electronic logic unit () information relating to the measured pressure, characterized in that the bleed-off apparatus () also comprises an inductive member () powered electrically by the electronic logic unit () and in that, when the bleed-off outlet () is connected up to the tap (), the inductive member () of the bleed-off outlet () is situated in a manner adjacent to the inductive member () of the manometer () so as to ensure electrical power supply of the manometer () by inductive coupling.

An installation for exchanging gas cylinders includes an enclosed space preferably with controlled access, at least a couple of stations, one for depositing an article to be exchanged and the other for collecting an article to be taken away, each station having a device for retaining the article that can be switched between an open configuration and a locked configuration, the retaining devices of the two stations being coupled such that the locking of one retaining device around an article to be deposited in the deposit station authorizes at least temporarily the opening of the retaining device of an article to be taken away for its removal.
