Abstract

Le turbocompresseur centrifuge (2) comporte un carter hermétique (3) ; un arbre d'entraînement (6) ayant un axe longitudinal et agencé en rotation à l'intérieur du carter hermétique (3) ; un étage de compression comportant une roue (17) reliée à l'arbre d'entraînement (6) ; une entrée d'aspiration de gaz (42) ; et un trajet de flux de gaz (P) relié fluidiquement avec l'entrée d'aspiration de gaz (42) et configuré pour alimenter l'étage de compression en flux de gaz. Le trajet de flux de gaz (P) comporte une chambre de détente (46) entourant au moins partiellement l'arbre d'entraînement (6), l'entrée d'aspiration de gaz (42) débouchant sensiblement radialement dans la chambre de détente (46) ; et une pluralité de canaux de guidage de flux d'entrée (51) reliés fluidiquement avec la chambre de détente (46) et répartis angulairement autour de l'axe longitudinal de l'arbre d'entraînement (6), les canaux de guidage de flux d'entrée (51) s'étendant radialement vers l'arbre d'entraînement (6) et étant axialement décalés par rapport à l'entrée d'aspiration de gaz (42) et à la chambre de détente (46).
