Abstract
La présente invention a pour objet un perfectionnement aux pompes hydrauliques à plateau biais ayant pour objet de leur permettre de fonctionner avec le même rendement quel que soit leur sens de rotation. A cette fin la lunule d'alimentation est disposée symétrique par rapport à la ligne de plus grande pente du plateau. L'invention est destinée à toutes applications hydrauliques.
