FIELD: hydraulic engineering.
SUBSTANCE: invention relates to hydraulic machine building, namely, to rotary motor. Motor comprises housing 1, rotor 2, inlet and outlet distributors 4 and 5, inlet and outlet branch pipes 6 and 7, and bearings. Rotor 2 has cylindrical shape. Cylindrical surface of rotor 2 has recesses in the form of truncated cone. Rotation axis of recesses is arranged at right angle to rotor 2 rotation axis. Recesses are distributed along rotation axis of rotor 2 in number of four rows, and rows are displaced along circumference of rotor 2 at equal angle relative to each other. In housing 1 there are four through holes aligned with holes made in distributors 4, 5.
EFFECT: invention is aimed at increasing high torque, rotation speed, manufacturability, assembly and repair.
