Abstract

L'invention concerne un système d'injection (18) d'un mélange air-carburant pour chambre de combustion de turbomachine, et un injecteur de carburant (80) comprenant un nez d'injecteur (82) au moins partiellement annulaire autour d'un axe de nez d'injecteur (82). Selon l'invention, le nez d'injecteur (82) comprend une semelle de maintien (101) qui est en saillie du nez d'injecteur (82) radialement vers l'extérieur du nez d'injecteur (82). La semelle de maintien (101) est configurée pour être insérée dans un espace de logement (29) d'une partie fixe (25) de système d'injection (18), de sorte à former un moyen de centrage et de retenue axiale de l'injecteur (80) relativement à la partie fixe (25) de système d'injection (18).The invention relates to an injection system (18) for an air-fuel mixture for a turbomachine combustion chamber, and a fuel injector (80) comprising an at least partially annular injector nozzle (82) around an injector nose pin (82). According to the invention, the injector nose (82) comprises a holding flange (101) which projects from the injector nose (82) radially outwardly of the injector nose (82). The holding flange (101) is configured to be inserted into a housing space (29) of a fixed part (25) of the injection system (18), so as to form an axial centering and retaining means of the injector (80) relative to the fixed part (25) of the injection system (18).
