STATION AND METHOD FOR FILLING A TANK WITH A FUEL GAS

摘要

The invention relates to a station (1) and method for filling a tank (7) with a fuel gas. Said station includes at least one fuel gas source store (3) and a gas transfer system (8) having a first upstream end connected to the source store(s) (3) and a second downstream end that is in fluid communication with the tank (7). The gas transfer system (8) includes at least one control valve (9, 10), characterized in that the at least one source store (3) includes a rigid outer wall and a flexible sealing wall (2) that is arranged inside the space defined by the rigid outer wall. The flexible wall (2) defines a storage space for the fuel gas. The first upstream end of the system (8) is connected to the storage space defined by the flexible wall (2). The at least one control valve is also characterized in that the space located between the flexible wall (2) and the outer wall is connected to a system (12, 13) for transferring liquid into the source store (3) in order to fill or extract the liquid in the source store (3) and control the pressure in the store (3) when filling and/or extracting fuel gas within the sealing wall (2).
