Abstract
Il s'agit de mouiller en permanence la lèvre 2 d'un joint d'étancheité pour arbre rotatif horizontal 1 à l'aide d'un liquide présent en quantité réduite d'un côté A de ce joint. On a recours à cet effet à une rondelle élastique 20 évidée d'encoches radiales 21 et dont la périphérie 23 est entraînée par l'arbre de sorte que les rotations de cet arbre soumettent le liquide présent dans les encoches à une force centripète qui envoie celui-ci au contact de la lèvre. Application aux arbres susceptibles de tourner indifféremment dans l'un ou l'autre sens.
