Abstract

La présente invention concerne un dispositif de ventilation (17) pour un carter de stator (11) d’une turbomachine (1), comprenant :- au moins un conduit de passage (20) d’un flux d’air (F2) dont une première portion (21) forme une entrée d’air et une seconde portion (22) forme une sortie d’air,- au moins un boîtier (24) de distribution d’air dans lequel débouche la seconde portion (22) et comportant une pluralité de rampes (25) destinée à s’étendre autour du carter,- la seconde portion est reliée par des organes de liaison (30) au boîtier, les organes (30) étant configurés pour autoriser un mouvement axial de la seconde portion (22) vis-à-vis du boîtier (24) suivant un premier axe (X) du conduit (20) et/ou un mouvement angulaire de la seconde portion vis-à-vis du boîtier autour du premier axe, d’un second (Y) et d’un troisième (Z) axes perpendiculaires au premier axe (X).
