Abstract:
An annular shroud (42), having an internal face intended to cover the back end wall (33) of an annular combustion chamber (12) of a turbomachine (14) fitted with a centrifugal compressor, together with an external face opposite said internal face, and where said shroud includes multiple apertures (54) intended to allow fuel injectors (38, 40) supported by said back end wall (33) to pass through, together with multiple bosses (56) which extend as projections on said external face radially towards the interior respectively from the respective radially internal edges (58) of said apertures (54), such that each of said bosses (56) delimits an extension (60) of the corresponding aperture (54) open radially towards the exterior so as to form an air intake scoop.
