Abstract

L'invention concerne un ensemble injecteur conçu pour une chambre de combustion (103) d'un moteur (T), comprenant au moins un injecteur (D) pour injecter du carburant dans un espace de combustion (1030) de la chambre de combustion (103), l'injecteur(D) comprenant un corps principal d'injecteur (DR) qui s'étend le long d'un axe longitudinal d'injecteur (L) et comporte une tête d'injecteur (DK) et un porte-injecteur (DH) qui est relié au corps principal d'injecteur (DR) et comporte au moins une conduite d'alimentation en carburant (1). Le corps principal de buse (DR) comprend un tuyau de carburant (3) central s'étendant le long de l'axe longitudinal d'injecteur (L) et sur la tête d'injecteur (DK) au moins deux canaux de guidage d'air (4, 5) espacés radialement l'un de l'autre et pourvus respectivement d'au moins une ouverture de sortie d'air.
