摘要：
The invention concerns a gas delivery device (1) comprising an inner gaspassage(100) in fluid communication with a deformable reservoir (27), and aprocessing unit(51), such as an electronic board with a microcontroller. It further comprisesreservoirdetection means (26, 260) cooperating with the deformable reservoir (27) andwith theprocessing unit (51) for determining a distance (D) between said reservoirdetectionmeans (26, 260) and said deformable reservoir (27), and a proportional valve(22)arranged on the inner gas passage (100) for controlling the flowrate of gas insaid innergas passage (100). The processing unit (51) controls the proportional valve(22) foradjusting the flowrate of gas traversing said proportional valve (22) on thebasis of saiddistance (D) between the reservoir detection means (26, 260) and thedeformablereservoir (27).
