The invention relates to radial piston hydraulic motors of multiple actions, in particular to a hydraulic motor whose rotor is equipped with shaped cams. In the well-known Hzdromotors of this type, the rotor is mounted on a bearing located on the outer sides of its grooved cams, and the outer bearing cages are mounted to the motor case and its core. This increases the axial dimensions of the hydra motor. The aim of the invention is to achieve the dimensions of a hydraulic shaker. This is achieved by the fact that the rotor is made of two parts and is provided in the area between the cam-mounted landing surfaces under the inner bearing cages, the outer cages of which are located in the axial bores of the stator, made of two bonded bottom cylinders - the inner and the outer, and in the inner cylinder Radial grooves are made in which the crossbars and axial bores are placed, and bores for the installation of pistons are made in the outer cylinder. FIG. 1 depicts the described hydraulic motor, a longitudinal section; in fig. 2 is a section A-A in FIG. 1. The radial piston hydraulic motor of multiple action contains a rotor consisting of two connected parts 1 and 2, each of which contains a profiled cam. The rotor is mounted on bearings 3 in a stator consisting of two hollow cylinders — an inner 4 and an outer 5, fastened with an element 6. An outer hole is made in the outer cylinder 5 to install the pistons 7, and in the inner cylinder 4 there are radial grooves in which traverse beams are placed 8 with rollers 9. Rollers 9 interact with profiled cams, made on parts x 1 and 2 of the rotor. The piston holes in the outer cylinder 5 are closed with arcuate bolts 10 and 11 with seals 12. The bolts 10 and 11 are fastened with screws 13. The piston orifices of the outer cylinder 5 are connected by channels 14 to the distribution windows of the rotating sleeve 15 associated with the part. 2 rotors by means of a hinge element 16. The sleeve 15 is provided with channels 17 and 18, which communicate with annular grooves 19 and 20 in the outer cylinder 5, to which the pressure and discharge lines are connected. When the hydraulic motor is working, the working fluid from the pump enters the annular groove 19 of high pressure and then through the channel 17 of the sleeve 15 enters the distribution ports and through the channel 14 into the over-piston space. The force generated by the pressure of the working fluid acts on the piston 7 and through the yoke 8 and the rollers 9 is transmitted to the rotor's shaped cams. The tangential component of this force rotates the hydromotor rotor. Spent working Zhvdko under pressure drain through the channel 18 of the sleeve 15 and through the groove 20 enters the drain line.
