Abstract
A device for filling a tank or tanks with pressurized gas comprising a circuit comprising a plurality of upstream ends connected respectively to separate pressurized gas sources, at least one compressor, at least one buffer storage, a set of controlled valves and at least one downstream end intended to be connected to the tank(s) to be filled, the device further comprising an electronic control member configured to control the valves and/or the compressor in order to ensure a transfer of gas into the tank from at least one source and/or at least one buffer storage and/or via the compressor, the device comprising a set of sensors for measuring the pressure in the sources and the buffer storages, the control member comprising member for receiving or generating signal representative of the filling demand from a relatively high demand to a relatively low demand, the control member being configured to ensure the transfer of gas into the tank according to at least a first transfer mode using the source having the highest pressure and a second transfer mode using a source having a pressure lower than this highest pressure in response, respectively, to a relatively high or low filling dema…
