Abstract

L’invention concerne un dispositif d’étanchéité (7) comprenant deux armatures interne (8) et externe (9) formant entre elles une chambre annulaire (12) débouchant vers l’extérieur par un passage amont (13) formé à l’interface entre une paroi intérieure (19) d’une portion extérieure (8a) qui entoure une paroi extérieure (20) d’une portion extérieure (9c), la paroi extérieure (20) présentant un bord interne (20b) et un bord externe (20a) formant entre eux une gouttière annulaire (21) communiquant avec l’extérieur par une ouverture amont (21a) formée à l’interface entre le bord externe (20a) et la paroi intérieure (19) et avec la chambre annulaire (12) par une ouverture aval (21b) formée à l’interface entre le bord interne (20b) et la paroi intérieure (19), la dimension de passage (Da) de l’ouverture amont (21a) étant supérieure à la dimension de passage (Db) de l’ouverture aval (21b).
