Abstract

Pompe à engrenages. Dans une pompe à engrenages dans laquelle on dérive un peu du liquide pompé pour assurer la lubrification des paliers, l'orifice de prise (dépression 50 et canal 52) est légèrement décalé par rapport à la ligne des centres vers le côté aspiration de la pompe. Le liquide ainsi prélevé circule dans les paliers de chaque côté des engrenages. Application aux pompes à huile ou autre liquide comportant un certain pouvoir lubrifiant.
