Abstract

L'invention concerne un compresseur (22 ; 260 ; 300 ; 400) qui possède un ensemble corps (140) ayant un orifice d'aspiration (24), un orifice de refoulement (26) et un orifice d'économiseur (58). Un rotor (154) est monté de façon à être entraîné dans au moins un premier état de manière à aspirer un flux principal de fluide à travers l'orifice d'aspiration et à refouler le fluide par l'orifice de refoulement. Un diffuseur (220 ; 302 ; 402) possède une pluralité de passages de diffuseur (222 ; 310 ; 308 ; 403). Chaque passage de diffuseur présente une entrée (224) positionnée pour recevoir un fluide du rotor et une sortie (220) en aval de l'entrée dans le premier état. Un ou plusieurs passages (230, 231, 232, 234, 236, 268 ; 320, 330, 332 ; 412) sont positionnés pour attirer un flux de fluide d'économiseur à travers l'orifice d'économiseur et pour débiter le flux d'économiseur en aval de l'entrée du rotor (212) mais en amont des sorties du passage de diffuseur (226).
