The invention relates to an inflating device containing a pressurized gas chamber arranged in a housing. To achieve small dimensions and a cheap structure, never-the-less maintaining a large capacity for the device, the pressure chamber constitutes a standard type of gas bulb (2), a discharge duct (7) in communication with the chamber being formed to provide ejector action for inducting air via secondary air passages (11) leading from the duct (7) to the outside of the housing and suitably provided with non-return valves. |
