Title
(EN) SEAL FOR A DISCHARGE VALVE DOOR OF A TURBOMACHINE
(FR) JOINT D'ETANCHÉITÉ POUR PORTE DE VANNE DE DÉCHARGE D'UNE TURBOMACHINE
Abstract
(EN)
The invention relates to a seal (20) configured to be mounted on a first member of a turbomachine (100), such as a door (16) of a discharge valve (10), and to come to bear against a second member (11, 12, 128) of the turbomachine, such as a hub (11) of an intermediate casing (12), said seal being characterized in that it comprises: latching means (21) for mounting said seal on said first member; a sealing lip (24) that seals with respect to air by contact and that is intended to come to bear against said second member (11, 12, 128); means (23) for preventing said sealing lip (24) from being turned back, increasing the stiffness of the seal (20) at the base of the sealing lip (24).
(FR)
L'invention se rapporte à un joint d'étanchéité (20) configuré pour être monté sur un premier organe de turbomachine (100), tel qu'une porte (16) d'une vanne de décharge (10), et pour venir en appui contre un deuxième organe (11, 12, 128) de la turbomachine, tel qu'un moyeu (11) de carter intermédiaire (12), ledit joint d'étanchéité étant caractérisé en ce qu'il comporte : des moyens d'accroche (21) pour monter ledit joint sur ledit premier organe; une lèvre d'étanchéité (24) assurant une étanchéité à l'air par contact et destinée à venir en appui contre ledit deuxième organe (11, 12, 128); des moyens anti-retournement (23) de ladite lèvre d'étanchéité (24) renforçant la rigidité du joint d'étanchéité (20) à la base de la lèvre d'étanchéité (24).
