CA 2750856

The invention relates to a diffuser/rectifier assembly to be mounted at the outlet of a compressor in a turbine engine, including a rectifier (18) including two substantially cylindrical radially inner (26) and outer (28) walls connected by radial vanes (30), characterised in that the walls of the rectifier extend downstream beyond the radial vanes (30) and in that the radial spacing thereof is variable downstream from the vanes (30) so as to be at a minimum substantially in alignment with the vanes (30) and at a maximum between the vanes (30).

Ensemble diffuseur-redresseur destiné à être monté en sortie d'un compresseur dans une turbomachine, comprenant un redresseur (18) comportant deux parois sensiblement cylindriques radialement interne (26) et externe (28) reliées par des aubes radiales (30), caractérisé en ce que les parois du redresseur sont prolongées vers l'aval au- delà des aubes radiales (30) et leur écartement radial est variable en aval des aubes (30) de façon à être minimal sensiblement dans le prolongement des aubes (30) et maximal entre les aubes (30).
