Abstract

a. L'invention concerne un palier à roulement, notamment pour pompes. b. Palier à roulement monobloc caractérisé par un dispositif d'étanchéité, disposé entre la bague fixe et l'axe rotatif, ce dispositif d'étanchéité comportant un premier organe d'étancheité, au voisinage de la turbine de la pompe retenant le liquide et un second organe d'étanchéité, incorporé au roulement pour y maintenir le lubrifiant, ces deux organes d'étanchéité délimitant entre eux une cavité pourvue d'au moins un canal d'écoulement pour recueillir et évacuer le liquide de suintement, les deux organes d'étanchéité sont constitués d'armatures annulaires sur lesquelles sont fixés les joints d'étanchéité proprement dits. c. L invention trouve son application principale dans la réalisation de pompes destinées à véhiculer un liquide de refroidissement dans les voitures automobiles.
