Abstract

La présente invention concerne un dispositif d'injection de carburant dans lequel un injecteur de carburant (2), une butée (3) et un tuyau d'alimentation en carburant (1) peuvent être assemblés de manière efficace. L'injecteur de carburant (2), la butée (3) et le tuyau d'alimentation en carburant (1) sont reliés de manière préliminaire dans une relation de position prédéterminée, et supportés et fixés par un support en résine (5), ou un support en plaque métallique, ou analogue. En conséquence, il est possible de manipuler l'injecteur de carburant (2), la butée (3) et le tuyau d'alimentation en carburant (1) sous la forme d'une seule pièce.
