摘要:
The invention concerns a gas delivery device (1) comprising an inner gas passage (100) in fluid communication with a deformable reservoir (27), and a processing unit (51), such as an electronic board with a microcontroller. It further comprises reservoir detection means (26, 260) cooperating with the deformable reservoir (27) and with the processing unit (51) for determining a distance (D) between said reservoir detection means (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 in said inner gas passage (100). The processing unit (51) controls the proportional valve (22) for adjusting the flowrate of gas traversing said proportional valve (22) on the basis of said distance (D) between the reservoir detection means (26, 260) and the deformable reservoir (27).
