Abstract

La présente invention concerne un injecteur de carburant (1) comprenant un canal de carburant (2), un gicleur (3), et des moyens de refroidissements avec circulation d’un fluide s’étendant le long du canal de carburant. Les moyens de refroidissement comprennent un premier passage (6) autour du canal de carburant, et un deuxième passage (9) autour du premier passage (6). Les moyens de refroidissement sont configurés pour que le fluide de refroidissement passe successivement dans le premier passage (6) puis dans le deuxième passage (9) en sens opposé. Figure 2 à publier FiguresThe present invention relates to a fuel injector (1) comprising a fuel channel (2), a nozzle (3), and cooling means with circulation of a fluid extending along the fuel channel. The cooling means comprise a first passage (6) around the fuel channel, and a second passage (9) around the first passage (6). The cooling means are configured so that the cooling fluid passes successively in the first passage (6) then in the second passage (9) in the opposite direction. Figure 2 to publish Figures
