Abstract
L'invention concerne un ensemble pour une turbomachine (1), comportant un canal annulaire (6) destiné à former une veine d'écoulement d'un flux de gaz entre deux étages (2, 3) de turbine de la turbomachine (1), ledit canal (6) étant délimité par une paroi annulaire radialement interne (7) et une paroi annulaire radialement externe (8), lesdites parois (7, 8) étant reliées par des bras creux (16) s'étendant radialement, un support (17) comportant une partie annulaire radialement externe (9), située radialement à l'extérieur de la paroi annulaire externe (8) du canal annulaire (6), et une partie annulaire radialement interne (12), située radialement à l'intérieur de la paroi annulaire interne (7) du canal annulaire (6), les parties externe et interne (9, 12) du support (17) étant reliées par des parties de liaison (18) s'étendant radialement, chaque partie de liaison (18) traversant l'un des bras creux (16) du canal annulaire (6).
