Abstract

L'invention concerne un assemblage (100) pour turbomachine d'aéronef comprenant un premier élément de stator (102) et un second élément de stator (104) entre lesquels est défini un espace sensible (108) vis-à-vis d'un fluide, l'assemblage comprenant un dispositif (110) de circulation du fluide conçu pour traverser l'espace sensible (108) et comprenant une première canalisation (120) de circulation du fluide. Selon l'invention, le dispositif (110) comporte également une seconde canalisation (122), des premiers et seconds moyens d'étanchéité (128, 132) étant interposés entre la seconde canalisation (122) et chacun des premier et second éléments (102, 104), la seconde canalisation (122) étant agencée autour de la première canalisation (120) et définissant avec celle-ci une chambre (124) de collecte de fluide de fuite présentant des moyens d'évacuation (134) agencés en aval des seconds moyens d'étanchéité (132).The invention relates to an assembly (100) for an aircraft turbomachine comprising a first stator element (102) and a second stator element (104) between which is defined a sensitive space (108) vis-à-vis a fluid, the assembly comprising a device (110) for circulating the fluid adapted to pass through the sensitive space (108) and comprising a first pipe (120) for circulating the fluid. According to the invention, the device (110) also comprises a second pipe (122), first and second sealing means (128, 132) being interposed between the second pipe (122) and each of the first and second elements (102 , 104), the second pipe (122) being arranged around the first pipe (120) and defining therewith a chamber (124) for collecting leakage fluid having discharge means (134) arranged downstream of the second sealing means (132).
