Abstract

Ce patin est du type comprenant une calotte sphérique formant rotule, sur laquelle s'appuie un piston. Selon l'invention, l'espace 17 recevant la calotte sphérique 12 et situé entre le piston Il et la calotte sphérique 2 est seulement lubrifié à travers un canal 15 qui traverse le patin et débouche dans sa semelle 14 à l'endroit où un champ de pression hydrodynamique 16 qui s'établit pendant le fonctionnement présente sa valeur maximale. L'invention est notamment applicable aux moteurs et aux pompes hydrauliques à pistons radiaux ou axiaux.
