Abstract

Le présent certificat d'addition décrit un certain nombre de perfectionnements à la disposition du brevet principal consistant à intercaler entre chaque injecteur ou groupe d'injecteurs et le fond d'une chambre de combustion, une partie intermédiaire de dimension réduite par rapport à celle de la chambre Ces perfectionnements consistent d'une part à aménager des dispositifs de refroidissement pour les extrémités de la partie intermédiaire, et d'autre part à augmenter le volume de la zone de recirculation dans le fond de la chambre. Application aux chambres de combustion de tout type, pour moteurs à turbines à gaz.
