Abstract

L'invention porte sur un procédé de fonctionnement d'une pompe/d'un moteur qui comprend le pompage d'un fluide de travail dans une rampe à haute pression au moyen d'un premier ensemble piston/cylindre, pendant que le piston dans le premier ensemble piston/cylindre se déplace d'une position de point mort inférieure à une position de point mort supérieure, et le transfert du fluide de travail de la rampe à haute pression au cylindre d'un second ensemble piston/cylindre pour déplacer le piston du second ensemble piston/cylindre d'une position de point mort supérieure à une position de point mort inférieure, transmettant ainsi un couple sur une came et un arbre de sortie, dans la même révolution complète de la came et de l'arbre de sortie pendant laquelle le fluide de travail est pompé dans la rampe à haute pression par le premier ensemble piston/cylindre.
