Abstract

Joint dynamique amélioré pour l’étanchéité d’un module de moteur d’aéronef Joint dynamique annulaire (100) pour l’étanchéité d’une enceinte interne (A) d’un module de moteur d’aéronef, comprenant un axe central (X), un premier anneau de joint (110) fixe fixé à une partie fixe (12) du module, un deuxième anneau de joint (120) mobile en rotation autour de l’axe central (X) et fixé à une partie mobile en rotation du module (10), le deuxième anneau de joint (120) étant disposé vis-à-vis du premier anneau de joint (110) pour former une interface axiale (I), le deuxième anneau de joint (120) comprenant une pluralité de canaux de pompage s’étendant à l’intérieur dudit deuxième anneau (120), entre une première extrémité débouchant sur une face radiale du deuxième anneau (120) et une deuxième extrémité débouchant sur l’interface axiale (I), les canaux de pompage étant configuré pour, lorsque le deuxième anneau de joint (120) est en rotation, ingérer de l’air par la première extrémité, et l’expulser par la deuxième extrémité. Figure pour l’abrégé : Fig. 3.Improved dynamic seal for sealing an aircraft engine module An annular dynamic seal (100) for sealing an internal enclosure (A) of an aircraft engine module, comprising a central axis (X ), a first fixed seal ring (110) fixed to a fixed part (12) of the module, a second seal ring (120) rotatable about the central axis (X) and fixed to a rotatable part of the module (10), the second seal ring (120) being arranged opposite the first seal ring (110) to form an axial interface (I), the second seal ring (120) comprising a plurality of pumping channels extending inside said second ring (120), between a first end opening onto a radial face of the second ring (120) and a second end opening onto the axial interface (I), the pumping channels being configured to, when the second seal ring (120) is rotated, ingest air through the first end, and the expu lser from the second end. Figure for abstract: Fig. 3.
