Abstract

L'invention concerne un ensemble de joint à face rotative et sans contact (10) qui comprend un premier élément d'étanchéité, comprenant une première face d'étanchéité et un premier élément magnétique (20); et un second élément d'étanchéité, comprenant une seconde face d'étanchéité et un second élément magnétique (30). Les premier et second éléments magnétiques (20, 30) des premier et second éléments d'étanchéité fournissent une force de répulsion magnétique entre les premier et second éléments magnétiques (20, 30) de telle sorte que la force de répulsion magnétique sépare les première et seconde faces d'étanchéité avant que des forces hydrodynamiques ou hydrostatiques associées à la rotation du second élément d'étanchéité ne deviennent suffisantes pour empêcher le contact entre les première et seconde faces d'étanchéité.
