The hydraulic motor works as follows.

When the working fluid is supplied to the working chambers 3, the blades 5 of the rotor 4 are loaded with a moment of force, under the action of which the rotor 4 performs a landing obratnoe movement on the fixed and movable conical wheels 8. When the rotor 4 teeth 7 interact with the movable conical wheel 8 teeth 23, the output shaft rigidly connected to the movable conical wheel 8, begins to rotate with an angular
