Abstract

Un joint (13) d'étanchéité obturant un jeu (9) entre une extrémité en forme de cloche (7) d'un bras (4) et une virole circulaire (1) d'une turbomachine est comprimé contre le rebord (8) de la cloche par un support (14) distinct de la plate-forme (10) délimitant la veine d'écoulement des gaz (5) et que retiennent des vis (11) déjà présentes pour fixer la plate-forme sur la virole (1). L'agencement est allégé et la tenue du joint ne dépend pas de la plate-forme (10) exposée à des dommages.
