A rotary hydraulic machine includes a body with main cylindrical cavity, inlet and outlet channels, separation devices and a rotary piston that is installed in the body cavity, has radial lugs and radial depressions at peripheral surface. To decrease wear of the elements of the separation devices and losses of energy each separation device is arranged as a three-blade dividing rotor installed in an opened separating chamber of the body that is opened to the body cavity due to intersection with it. The side surfaces of the blades of dividing rotors are arranged as concave with radii of curvature equal to the radius of curvature of the body cavity. Each dividing rotor is installed with possibility of discrete turns by 120° with stops, in such a way that in position of stop one of its side surfaces forms continuation of the inner cylindrical surface of the rotor cavity, and the blade of the rotor opposite to the surface divides the dividing chamber into the first and the second in direction of rotation of dividing rotor parts, the inlet elements go to the second parts of separating chambers, and the inlet channels go to the first parts of separating chambers. |
