Abstract
Ce dispositif est destiné plus particulièrement, bien que non exclusivement, à empêcher les fuites de lubrifiant à l'endroit où l'arbre d'un moteur sort à travers une paroi du carter. Le dispositif selon l'invention comprend un collet 6 sur un arbre 5 monté en rotation dans un palier 4 de type fourreau fixé dans la paroi du carter 1. Dans ladite paroi est prévu un lamage 2 dont la paroi cylindrique coopère avec une rainure hélicoïdale 6a formée sur la face cylindrique du collet 6 pour empêcher le lubrifiant du palier de passer par le jeu de fonctionnement entre le collet et la paroi du lamage. Un organe de fermeture 7 du lamage 2 présente une ouverture 8 par laquelle sort l'arbre et le bord de l'ouverture 8 du lubrifiant qui a eventuellement vaincu la résistance offerte par la rainure hélicoïdale ; ce dispositif est efficace lorsqu'un arbre est monté dans un palier de type fourreau avec un jeu de fonctionnement important.
