Abstract

L'invention concerne un turbocompresseur de véhicule automobile, comprenant : - un anneau porte-ailettes (22) sur lequel sont implantées des ailettes (24) pivotantes : - une surface annulaire (30) parallèle à l'anneau porte-ailettes et se trouvant du côté des ailettes ; - des entretoises (34) maintenant. l'anneau porte-ailettes à distance de la surface annulaire, un jeu fonctionnel nominal (e) étant formé entre la surface (30) et les ailettes en position fermée. La surface annulaire (30) comporte le long de son bord périphérique extérieur une échancrure annulaire (40) telle que, lorsque les ailettes sont en position ouverte, leur extrémité arrière se trouve en regard de l'échancrure annulaire (40) et fait avec celle-ci un jeu fonctionnel augmenté (E) supérieur audit jeu nominal.
