Abstract

L'invention concerne un turbocompresseur, en particulier pour l'alimentation dite << à bouffée >> (à onde de pression) des moteurs de véhicules et dont la turbine actionnée par les gaz d'échappement présente en conséquence une volute à plusieurs flux dont les canaux d'entrée ne convergent vers la périphérie de la roue de turbine que dans la zone précédant immediatement cette roue. Dans la zone où l'extrados et la périphérie de la roue de turbine forment un bord circulaire entraîné en rotation, est disposée une fente annulaire par laquelle une partie des gaz d'échappement en provenance de la volute pénètrent dans un canal circulaire 13 prévu sur l'extrados de la roue, canal circulaire d'où une tuyauterie de récupération 14 part vers le conduit d'air de suralimentation 15 du compresseur 3 et une tuyauterie 18, montée en bypass de la turbine 2, vers le tuyauterie de gaz d'échappement 19. Application à l'amélioration du comportement en service du moteur suralimenté au moyen du turbocompresseur.
