Abstract

L'invention concerne une pompe/moteur hydraulique multi-cylindrique, à cylindrée variable par inclinaison du barillet, du type dit << à axe brisé >>. L'invention consiste à faire passer le liquide à travers des ensembles piston-bielle 10 creux présentant des passages de circulation de liquide de grande section. On réalise ainsi un trajet direct du fluide et on obtient une lubrification permanente des rotules 12 des têtes de bielle. Application à la construction de pompes à débit variable et de moteurs à vitesse variable.
