Abstract

L'invention concerne une turbomachine, telle qu'un turboréacteur ou un turbopropulseur d'avion, comportant un compresseur centrifuge comprenant un rouet équipé de pales, et un couvercle annulaire (7) délimitant avec le rouet une veine annulaire (8) de circulation d'un flux d'air, ledit couvercle comportant une partie aval fixée à un carter de la turbomachine et une partie amont maintenue en position par rapport audit carter, par l'intermédiaire d'une virole annulaire (17). La virole (17) et le couvercle (7) délimitent entre eux un espace annulaire (27) dans lequel est ménagé un organe de retenue (28) solidaire de la virole (17), ledit organe de retenue (28) délimitant avec ladite virole (17) une gorge (31) dans laquelle est monté un organe d'étanchéité (34) annulaire, l'organe d'étanchéité annulaire (34) étant monté autour d'une partie (21) du couvercle (7) et étant maintenu en appui par l'organe de retenue (28) sur une partie (24) de la virole (17).The invention relates to a turbomachine, such as a turbojet or an aircraft turboprop, comprising a centrifugal compressor comprising an impeller equipped with blades, and an annular cover (7) delimiting with the impeller an annular flow path (8) 'an air flow, said cover comprising a downstream part fixed to a casing of the turbomachine and an upstream part held in position relative to said casing, by means of an annular ferrule (17). The ferrule (17) and the cover (7) define between them an annular space (27) in which is formed a retaining member (28) integral with the ferrule (17), said retaining member (28) delimiting with said ferrule (17) a groove (31) in which is mounted an annular sealing member (34), the annular sealing member (34) being mounted around a part (21) of the cover (7) and being held supported by the retaining member (28) on a part (24) of the ferrule (17).
