Abstract

L'invention a pour objet un moteur hydraulique (20) à cylindrée variable et pistons axiaux comprenant un carter (21) définissant une cavité (22) étanche renfermant deux pompes à pistons axiaux (15, 16) identiques, disposées à l'intérieur de ce même carter (21), et alignées de part et d'autre d'une glace de distribution de fluide (35) commune aux deux pompes (15, 16), fixée à l'intérieur de la cavité (22). Les applications vont notamment aux chaînes de traction de véhicules automobiles et notamment aux chaînes de traction hybride thermique/hydraulique.
