Abstract
The present invention relates to a device for injecting a liquid fuel into a pressurized air flow (7), in particular for a combustion chamber, comprising a hollow cylindrical body (10) of longitudinal axis (YY′) delimiting a substantially cylindrical central volume (11), fluid veins (12) substantially radial in relation to the longitudinal axis of body (10) and arranged on the periphery of said body to allow passage of said flow, and axial fuel injection pipes (5) arranged inside said fluid veins and connected to at least one fuel inlet (3) by at least one supply point (16). According to the invention, pipes (5) are pierced with openings (9) that open onto central volume (11) of said body (10) and which are oriented substantially in the direction of the flow in fluid veins (12).
