Abstract

Invention concernant des pompes. Ensemble de pompe pour système de freinage hydraulique qui comprend un carter comportant une entrée destinée à être reliée au réservoir à liquide, une sortie destinée à être reliée à un accumulateur hydraulique et un piston monté pour pouvoir prendre un mouvement de va-et-vient dans un alésage du carter de façon à aspirer du liquide dans une chambre de travail au cours d'une course d'admission et à le forcer à passer par la sortie au cours d'une course de puissance. On a prévu un mécanisme d'entraînement pour déplacer le piston dans un sens au cours de la course d'admission et le piston est déplacé en sens opposé au cours de la course de puissance en le soumettant à pression de la sortie. Application au freinage des véhicules.
