a tank containing the fire extinguishing liquid and provided with an expulsion outlet at a front end thereof;
a gas generator installed inside the tank at a rear end thereof, the gas generator enclosed in a rigid confinement enclosure fastened to the tank, the gas generator includes a gas outlet;
a diaphragm installed inside the tank to push back the fire extinguishing liquid towards the expulsion outlet under drive from a gas given off by the gas generator; and
a deflector connected to the rigid confinement enclosure, and arranged between the rigid confinement enclosure and the diaphragm,
wherein the diaphragm forms an inflatable bag connected in gastight manner to the gas outlet of the gas generator, the opening of the inflatable bag being directly fastened to the outside surface of the rigid confinement enclosure, the deflector being contained in the inflatable bag, the deflector includes an ejection passage for directing the gas given off by the gas generator rearwards of the tank and then to fill the inflatable bag, and the inflatable bag being folded prior to triggering of the gas generator in a confinement space defined by a cover and located inside the tank at a front of the gas generator.
