Abstract

L'invention propose un dispositif d'étanchéité glissant entre l'intérieur d'un corps de pompe hydraulique renfermant un premier fluide hydraulique et un arbre relais (6) tournant à l'intérieur d'un arbre creux (9) s'étendant au travers du corps de pompe hydraulique en y étant lubrifié par un deuxième fluide hydraulique distinct du premier fluide hydraulique, dispositif d'étanchéité qui comporte : - un premier joint d'étanchéité (11) comportant une armature rigide (12) qui comporte une bague (12a) qui délimite une portée intérieure (22R) de fixation de la bague (12) sur une portion de surface extérieure (24R) de l'arbre creux (9), notamment par frettage axial, et comportant une lèvre souple (11b) d'étanchéité en appui radial sur l'arbre relais (6) ; caractérisé en ce que la bague (12a) de l'armature rigide (12) comporte un revêtement interne d'étanchéité (30a) en matériau élastomère qui coopère avec une portion (24F) de surface extérieure (24) de l'arbre creux (9).
