Abstract
L’invention concerne un turboréacteur comportant un tube central rotatif (14) d’évacuation d’un flux d’air chargé de lubrifiant, ce tube central rotatif (14) étant porté par un support de tube aval fixe (17). Selon l’invention, le support de tube aval (17) est équipé d’un dispositif de coupe fixe (19) agencé pour longer une surface interne du tube central rotatif (14), afin de limiter la formation de dépôt à la surface interne de ce tube central rotatif (14) par effet de centrifugation de l’huile circulant dans le flux d’air et de cockéfaction de cette huile à la surface interne du tube.
