Abstract

L'invention se rapporte aux techniques mises en ÷uvre pour lutter contre les incendies et a pour objet, en particulier, des dispositifs extincteurs pour la production de mélanges aérosols gazeux pouvant être utilisés dans des locaux pour l'extinction d'incendies. Conformément à l'invention, un dispositif extincteur présente une enveloppe munie d'orifices, une charge disposée à l'intérieur et fournissant, lors de sa combustion, un mélange extincteur aérosol gazeux, ainsi qu'un système d'allumage, la charge utilisée étant une substance formant une scorie lors de sa combustion et étant disposée dans un ou plusieurs béchers placés à l'intérieur de l'enveloppe, en ménageant un espace intermédiaire vers ses parois, et qui sont orientés par leurs surfaces de base, en direction des orifices dans l'enveloppe, une perforation étant réalisée dans les parois latérales des béchers et la surface totale des fonds des béchers excédant la surface totale des orifices dans l'enveloppe.
