Abstract

La présente invention concerne un système d’injection (2) de carburant dans une chambre de combustion centrifuge (18) (1) comprenant :- une roue d’injection (14) configurée pour injecter du carburant dans la chambre de combustion centrifuge (18) ; et- une rampe d’alimentation (20) configurée pour alimenter en carburant la roue d’injection (14) présentant une face externe (21) au moins un joint d’étanchéité dynamique (26) comprenant une série de dents (27) s’étendant depuis une face externe (21) de la rampe d’alimentation (20) en direction d’une la face interne (15) de la roue d’injection (14). La face interne (15) de la roue d’injection (14) comprend par ailleurs au moins une irrégularité de surface (30) configurée pour modifier une composante radiale (Vr) d’une vitesse d’un fluide circulant au niveau du joint d’étanchéité dynamique (26).
