Abstract

Machine hydraulique dans laquelle chaque couple formé par un piston (50) et un logement (40) définit entre le piston (50) et le logement (40) une première chambre (60) et une seconde chambre (70) distinctes, le bloc cylindres (30) et le distributeur (165) présentent chacun une pluralité de conduits internes définissant un premier ensemble de conduits et un second ensemble de conduits, lesdits ensembles de conduits débouchant à l’interface entre le distributeur (165) et le bloc cylindres (30) selon deux rayons distincts par rapport à l’axe principal (Z-Z) et étant adaptés pour alimenter respectivement les premières chambres (60) et les secondes chambres (70). Figure pour l’abrégé : Fig. 2.
