Abstract
The invention relates to a gas generator comprising a combustion chamber filled with a solid propellant, a supply chamber filled with a fluid and a mixing chamber in which a hot gas generated by combustion of the solid propellant is mixed with the fluid. A combustion chamber wall is provided that has a plurality of outflow openings through which the hot gas escapes. A fluid feed chamber is provided so as to lie, in terms of flow, between the combustion chamber and the mixing chamber, the hot gas passing through the fluid feed chamber. The fluid from the supply chamber flows into the fluid feed chamber and the fluid feed chamber is radially open towards the outflow openings across the entire circumference of each of the outflow openings, so as to direct an annular fluid stream onto the hot gas.
