Abstract

Ensemble pour un compresseur de turbomachine, comprenant : - un rouet (7) de compression d'un flux d'air, mobile en rotation autour d'un axe longitudinal, - un système de diffusion (8) du flux d'air comprimé par le rouet (7), le système de diffusion (8), situé en aval du rouet (7), étant fixe et annulaire et comprenant un passage (10) de flux d'air comprimé présentant une partie coudée (8), l'ensemble étant caractérisé en ce que le système de diffusion (8) comprend, à l'intérieur du passage (10) du flux d'air comprimé, des aubes de diffusion (12a) s'étendant de manière continue entre un bord d'attaque (BA) des aubes (12a) situé en amont de la partie coudée (8b) et un bord de fuite (BF) des aubes (12) situé en aval de la partie coudée (8b).Assembly for a turbomachine compressor, comprising: - an impeller (7) for compressing an air flow, movable in rotation about a longitudinal axis, - a system (8) for diffusing the flow of compressed air by the impeller (7), the diffusion system (8), located downstream of the impeller (7), being fixed and annular and comprising a passage (10) for compressed air flow having a bent part (8), the assembly being characterized in that the diffusion system (8) comprises, within the passage (10) of the compressed air flow, diffusion vanes (12a) extending continuously between a leading edge (BA) of the vanes (12a) located upstream of the bent part (8b) and a trailing edge (BF) of the vanes (12) located downstream of the bent part (8b).
