摘要
The invention relates to an injection system (4) for a turbomachine combustion chamber. The injection system comprises a swirler (7) and a mixing bowl (8). The mixing bowl (8) comprises a converging frustoconical portion (82) and a diverging frustoconical portion (84). The diverging frustoconical portion (84) is connected to the converging frustoconical portion (82), forming a continuous aerodynamic profile with the converging frustoconical portion (82). The diverging frustoconical portion (84) is passed through by vortex holes (81) which each comprise a circumferential component around a longitudinal axis (X-X) of the injection system and an axial component along the longitudinal axis (X-X) of the injection system.
