Abstract

L'invention concerne un dispositif d'étanchéité (12) pour assurer l'étanchéité entre un carter (10) et un arbre (14) monté rotatif dans ledit carter (10), comprenant des premier (24) et second (26) joints à lèvre annulaires destinés à être disposés axialement côte à côte entre le carter (10) et l'arbre (14). L'invention se caractérise en ce que le dispositif comporte en outre des moyens (45,46,48) pour amener un flux de gaz (F) pressurisé dans une cavité annulaire (38) délimitée par le premier joint à lèvre (24), le second joint à lèvre (26) et une surface extérieure de l'arbre (22), de telle sorte que lors de la rotation dudit arbre (14), le flux de gaz (F,F1,F2) est apte à faire légèrement décoller au moins l'un des deux joints à lèvre (24,26) de la surface extérieure (22) de l'arbre (14) pour s'écouler hors de la cavité (38).
