Abstract

L'invention concerne un injecteur de carburant doté d'un canal de refroidissement (6) disposé dans la zone terminale du boîtier (1) côté chambre de combustion. L'invention vise à réaliser un bon refroidissement des zones thermiquement hautement sollicitées. A cet effet, le canal de refroidissement (6) est plus proche de l'alésage du pointeau (2) que de la face externe du boîtier (1) et il est pourvu d'une superficie de section dont la largeur maximale est égale à la hauteur mesurée dans le sens axial de l'injecteur.
