Abstract

La présente invention concerne un dispositif d'injection de carburant haute pression (1) destiné à un moteur à combustion interne, en particulier à un moteur à combustion interne à injection directe et allumage commandé, comprenant au moins une buse d'injection (4) qui est maintenue à une extrémité par une section d'enfichage (14), dans une tubulure de raccordement (6) d'un accumulateur de carburant haute pression (2), et à son autre extrémité dans un logement (10) d'une culasse (8) du moteur à combustion interne, au moins un élément d'étanchéité (16) étant intercalé radialement entre la section d'enfichage (14) et la tubulure de raccordement (6). Selon l'invention, l'élément d'étanchéité (16) est reçu par une chambre annulaire (18) formée dans la tubulure de raccordement (6), ladite chambre annulaire étant délimitée sur le côté orienté à l'opposé de l'accumulateur de carburant haute pression (2), par un épaulement annulaire (24) qui vient en prise avec l'élément d'étanchéité (16).
