Abstract
Joint d'étanchéité à labyrinthe. Ce joint comprend deux bagues extérieure et intérieure dont les surfaces en regard, de configuration identique, laissent subsister entre elles un interstice à profil en dents de scie, l'une ou l'autre desdites bagues étant susceptible de pivoter; le profil en dents de scie des bagues a un tracé tel que l'origine de l'interstice situé à un bout des bagues se trouve à une distance radiale qui est plus petite que la distance radiale correspondante de l'extrémité de l'interstice située à l'autre bout des bagues. Utilisable comme joint d'étanchéité à labyrinthe prêt à être monté.
