Abstract

L'invention concerne un carter en spirale (10), destiné à un compresseur radial, dans lequel est logé un insert en spirale (11) sur lequel sont formées des aubes directrices (12), et comprenant une bride d'aspiration (14) qui ferme le carter en spirale (10) et contre laquelle s'appuie l'insert en spirale (11) par son côté opposé aux aubes directrices (12). Selon l'invention, des vis (16) sont vissées dans la direction axiale dans l'insert en spirale (11), sur son côté tourné vers la bride d'aspiration (14), de manière à minimiser ou supprimer le jeu axial éventuellement présent entre l'insert en spirale (11) et la bride d'aspiration (14).
