Abstract

L'invention concerne une pompe à moteur à piston libre, avec régularisation du taux d'energie. Pompe à moteur à piston libre hydraulique utilisant plusieurs zones de piston hydraulique ou plusieurs pressions hydrauliques, avec une commande de distribution appropriée pour une mise en phase correcte de ces zones de pression, afin d'engendrer plusieurs taux de travail hydraulique, et, par suite, régulariser l'energie ou taux de travail du moteur à piston libre et minimiser l'emmagasinage d'énergie par inertie requis. Application à la fabrication des pompes.
