<p>A gas generator includes a case enclosing a combustion chamber containing at least one pyrotechnic charge, a diffusion chamber, and a chamber for storing a material releasable from the chamber during combustion of the charge, to change state endothermically under the effect of gas coming from this combustion, then be evacuated via the diffusion chamber. The material is a liquid stored at atmospheric pressure. The chamber has at least one inlet opening, and a series of outlet openings. The outlet openings are arranged within a wall separating the chamber from the diffusion chamber. The charge and the combustion and diffusion chambers are dimensioned such that during combustion, at least one portion of gas flow generated by the charge opens at least the inlet opening and penetrates into the chamber provoking the escape of the material via the outlet openings, then its endothermic change in state, mainly in the diffusion chamber.</p> |
