Abstract

L'invention concerne un injecteur de carburant pour turbomoteur fonctionnant avec divers carburants liquides ou gazeux. Il comprend un corps central 24 et une coque 28 définissant entre eux un passage de carburant gazeux 68, le corps central possédant un passage de carburant liquide se terminant par plusieurs gicleurs de carburant primaire 40 et un gicleur de carburant principal 42 obturable par une soupape 44, le carburant venant frapper une surface déflectrice conique 64, le gicleur principal s'ouvrant quand la pression de liquide est suffisante, le carburant liquide de même que le carburant gazeux passant par un passage de sortie 76 entre la coque et un déviateur 72 porte par la coque en aval du corps central, ledit passage de sortie etant parcouru par un courant d'air comprimé venant du compresseur du moteur.
