Abstract

Pompe à pistons comportant au moins deux cylindres à double effet dont chacun possède une première et une seconde enceintes de volume variable, et une commande pour le mouvement alternatif des tiges de pistons avec un décalage de phase pour chaque tige, caractérisée par le fait que les cylindres sont reliés entre eux en série de façon que la première enceinte du premier cylindre se trouve en communication avec la source d'aspiration et la seconde enceinte du dernier cylindre se trouve en liaison avec l'utilisateur de pression, la première enceinte de chaque cylindre étant en communication avec la seconde enceinte de ce cylindre à travers un clapet antiretour, la seconde enceinte de chaque cylindre étant reliée à la première enceinte du cylindre suivant, et par le fait que la commande est exécutée de façon qu'au cours du déplacement des pistons, à tout moment, au moins l'un des pistons se déplace à une vitesse constante. Cette pompe à pistons est destinée à être utilisée dans des installations où il est nécessaire d'assurer un débit régulier du liquide
