The present invention is directed to a chemical oxygen generator to produce cool oxygen gas comprising: a. a charge housing, b. a solid but porous charge contained in the said housing, the charge being made of a chemical mixture that generates oxygen upon decomposition and that will undergo a self- sustained exothermal decomposition after initiation, the said charge containing at most 3.0 wt.% of binder material,the said porous charge allows the generated oxygen to pass through the charge without damaging the virgin material and without creating volumetric burning,the said charge is mounted in the housing in such a way that the generated oxygen passes through the charge andunder the pressure difference flows from the moving decomposition front towards the vent, c. an ignition device mounted at one end of the cartridge in such a way that it is capable to initiate a self-sustained decomposition of the charge at the charge surface adjacent to the initiator, d. one or more vents mounted in such a way that the generated oxygen that has passed through the generating porous charge leave the gas generator through the said vents.
L'invention concerne un générateur de gaz oxygène chimique refroidi, qui comprend: a) une enceinte de charge; b) une charge poreuse mais solide, à l'intérieur de l'enceinte, sous forme de mélange chimique engendrant de l'oxygène sur décomposition, et subissant une décomposition exothermique auto-entretenue après lancement, ladite charge contenant au plus 3 %, en poids, de matériau liant et laissant l'oxygène la traverser sans endommager la matière vierge et sans entraîner de combustion volumétrique, et enfin ladite charge étant implantée dans l'enceinte de sorte que l'oxygène engendré traverse la charge et, sous l'effet de la différence de pression, transite du front de décomposition mobile vers un orifice d'évacuation; c) un initiateur à une extrémité de la cartouche, dans une configuration capable d'amorcer une décomposition auto-entretenue de la charge à la surface de charge adjacente à l'initiateur, d) un ou plusieurs orifices d'évacuation permettant l'évacuation de l'oxygène engendré qui a traversé la charge poreuse.
