Abstract

L'invention a trait à un palier comportant deux éléments pouvant tourner l'un par rapport à l'autre dont deux surfaces de tourillonnement tournées l'une vers l'autre coopèrent, une des deux surfaces ou les deux étant pourvues de trois motifs de gorges de pompage de lubrifiant parallèles et peu profondes, les deux motifs extérieurs présentant des gorges qui pompent dans le même sens, tandis que le motif intermédiaire présente des gorges qui pompent dans un sens opposé au premier. Application au graissage des paliers.
