Abstract (en)

[origin: EP2548619A2] The device has an inlet to be connected to a cartridge (2) of compressed gas i.e. carbon dioxide at high pressure, for allowing the gas to expand into an air intake chamber (32). The intake chamber has an opening (6) allowing atmospheric air to be admitted and an outlet (28) to be connected to an inflatable bag. An intermediate distribution chamber is arranged between the inlet and the intake chamber for connecting the inlet to the intake chamber. Ejection holes are formed to open into a lateral wall of the intake chamber to connect the intake chamber to the intermediate distribution chamber.
