Abstract

L'invention concerne un palier à roulement comprenant un organe intérieur (1) et un organe extérieur (2) formant entre eux un espace de roulement présentant une ouverture externe (9) et une ouverture interne (10) formant entre elles un chemin de circulation au travers dudit espace, au moins une desdites ouvertures étant équipée d'un dispositif d'étanchéité comprenant une armature (11) solidaire d'un organe (1, 2), ladite armature étant agencée pour former au moins un passage (12) dans lequel le chemin de circulation débouche, le dispositif d'étanchéité comprenant un élément d'étanchéité (14) qui est monté relativement à l'armature (11) entre un état d'occultation au moins partiel des passages (12) et un état d'ouverture desdits passages, ledit élément d'étanchéité étant agencé pour pouvoir passer réversiblement d'un état à l'autre en fonction du sens de circulation d'un flux de fluide dans le chemin.
