ROTARY HYDRAULIC MOTOR Russian patent published in 2019 - IPC F03B5/00 

FIELD: hydraulic engineering.

SUBSTANCE: invention relates to hydraulic machine building, namely, to rotary hydraulic motor. Hydraulic 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 is of cylindrical shape, on surface of which there are recesses in the form of truncated cone for interaction with liquid. Recesses are distributed along rotation axis of rotor 2 in rows, which are offset along circumference of rotor 2 at equal angle relative to each other. In housing 1 are displaced holes for inlet and outlet of liquid height to provide area of action of liquid on recesses. Angle of section of action of liquid on recesses is not less than angle of distribution of recesses along circumference of rotor 1.

EFFECT: invention is aimed at increasing of torque, rotation frequency, manufacturability, assembly and repair.
