Abstract

L'invention concerne un turbocompresseur à gaz d'échappement pour un moteur à combustion interne, comprenant une section de guidage d'air (7) pouvant être traversée par l'écoulement, une section de guidage de gaz d'échappement (5) pouvant être traversée par l'écoulement, et une section de palier (8) dans laquelle un rotor de turbocompresseur est supporté de manière à pouvoir tourner autour de son axe de rotation, et une roue de compresseur du rotor de turbocompresseur étant reçue de manière rotative dans la section de guidage d'air (7) pour aspirer et comprimer notamment de l'air frais, et une roue de turbine du rotor de turbocompresseur étant reçue de manière rotative dans la section de guidage de gaz d'échappement (5) pour entraîner la roue de compresseur, et un dispositif de réglage (9) étant prévu pour réguler un débit massique de gaz d'échappement du moteur à combustion interne (2) à travers la roue de turbine, le dispositif de réglage (9) pouvant être ajusté à l'aide d'un actionneur (10), l'actionneur (10) étant reçu au niveau de la section de guidage d'air (7). Selon l'invention, pour la stabilisation de l'actionneur (10) pendant le fonctionnement du turbocompresseur à gaz d'échappement (1), il est prévu un élément de support (11), l'élément de support (11) étant connecté à une extrémité à la section de guidage d'air (7) et à l'autre extrémité à un composant supplémentaire (13, 14) qui présente une dilatation thermique adaptée à la section de guidage d'air (7).
