Abstract

Pompe ou moteur dont deux pignons en prise tournent à l'intérieur du corps ou carter avec interposition de plaques de butée. Chaque plaque de butée en une pièce, qui est en métal plus mou que celui des pignons, comporte deux trous de passage des bouts d'arbres des pignons et, sur la face arrière, deux gorges annulaires 26 et 27 qui entourent ces trous, une gorge 28 qui les relie et des gorges 30 et 31 qui partent radialement des gorges annulaires pour aboutir à la périphérie de la plaque du côté opposé à celui de la gorge 28; une garniture d'étanchéité ayant le contour des gorges combinées est logée dans celles-ci de manière à former sur la face arrière de la plaque quatre poches qui sont mises à la même pression que celle qui règne à l'intérieur du moteur ou de la pompe Application générale aux moteurs et pompes à engrenage à haute pression.
