Abstract

Un turbocompresseur comprend une zone d'ailettes formée entre un élément de buse (21) et un insert flottant (17) supporté sur le carter d'échappement (7), cet insert flottant (17) étant poussé contre les ailettes (27) situées dans la zone d'ailettes par un élément poussant (43). Grâce à cet agencement on améliore l'efficacité de la turbine et on évite, dans une grande mesure, le risque de collage des ailettes.
