Abstract (en)
The present invention relates to a device enabling a treatment receptacle (1) to be filled with a pressurized gas, and the gas present in the treatment receptacle to be removed and stored. This device comprises; a storage reservoir (2) for the gas, composed of a rigid reservoir (3) and a deformable reservoir (4); a pipe (5) with a valve (6) connecting the reservoir (4) to the receptacle (1); a pipe (11) connecting the reservoir (4) to the treatment receptacle, the second pipe comprising a pumping means (12); a means (9) for supplying pressurised air in order to fill the space (7) situated between the rigid and deformable reservoirs with pressurised air; and a second valve (13) enabling the space (7) to be connected to the open air. <IMAGE>
