ABSTRACT:
Rotary hydraulic device comprising a stator 1, a rotor 2 and closing flanges together forming a tore that can amount to several meters in diameter. The rotor 1 has radial grooves 3 each receiving a valve 4 whose lower face moves on the periphery of the stator which provides swept-volume recesses A, B, C, D limited by a cylindrical part r connected to the periphery of radius R by ramps, the differential valves 4 receiving the thrust of the drive fluid through conduits coming out in the swept volumes.
