    A hydraulic device includes an internally toothed stator formed by a one-piece homogeneous body having a continuous inner wall defining a series of circumferentially spaced arcuate recesses each of which is dimensioned to receive a radially and circumferentially shiftable roller vane. The continuous inner wall further includes a series of radially oriented notches which are disposed between the arcuate recesses and which serve to make portions of the stator wall defining the arcuate recesses resiliently deflectable as a function of the forces applied to the rollers vanes. Further, the notches direct fluid flow to and from expanding and contracting fluid pockets defined between the roller vanes and the teeth of an externally toothed rotor located within the stator.

    I
    The invention relates to mechanical engineering, in particular to rotary machines with partially elastically deformable walls of working chambers.
    It is known a hydraulic device g containing gearing with two; 1 m is meshed with gear elements forming a series of fluid chambers that are installed with the possibility of planetary motion relative to each other, the first of which has internal teeth formed by cylindrical rollers mounted in the arcuate grooves with the possibility of displacement in the radial direction and on the circumference-A, and the second gear element has an outer tooth, and the quantities in them. one less than the first gear element, and the switching device l
    A disadvantage of the known hydraulic device is the large i-nose of the walls of the toothed cell with internal teeth.
    The purpose of the invention is to reduce the wear of the walls of the toothed element with internal teeth.
    This goal is achieved by the fact that on the surface of the gear element with internal teeth of the Meida, arcuate grooves are made around the circumferential grooves, the number of which is equal to the number of arcuate grooves, while the dimensions of the grooves and cylindrical rollers are selected from the condition of elastic deformation of the wall-arcuate grooves.

    The switching device is made in the form of a valve valve connected to a gear element with external teeth 1i, on the front side of which there are a series of pairs of holes around the circumference, one of which is permanently connected to the high pressure chamber, and the other to the low pressure chamber. At least part of the fluid openings are located opposite the arcuate recesses. FIG. 1 shows a hydraulic device, a longitudinal section; FIG. 2 shows the axially toothed element with external teeth; in fig. 3section A-A in FIG. - I; in fig. 4 gearing diagram. The hydraulic device has a gearing with two gearing gears 1 and 2, forming a series of liquid chambers 3, which are mounted with the possibility of planetary motion relative to each other, the first of which has internal teeth formed by cylindrical rollers 4, installed in Shaped grooves 5 are displaceable in the radial direction and rto circumference, and the second gear element has external teeth .6, and a switching device made in. The valve plate 7 is connected to the toothed element 2 with external teeth 6, on the front side 8 of which there are a series of pairs of holes 9 and Y. one of which is permanently connected to the high-pressure chamber 11, the other to the low-pressure chamber pressure (not shown), On the surface of the gear element 1 with internal teeth formed by cylindrical rollers 4 between the arcuate notches 5 grooves 12 spaced apart around the circumference, the number of which is equal to the number of arcuate notches 5, the hydraulic device in the engine mode works as follows. When high-pressure working fluid is supplied to chambers 3, for example, on the left side of the eccentricity line, and when displacing the working fluid from chamber 3, which are on the right side of the eccentricity line, the gear element 2 is applied torque, under the action of which it rotates around its axis and at the same time a planetary movement relative to gear element I, In this case, as shown in FIG. 4, on a cylindrical roller 4 A force is applied, pressing it to the surface The bones of the arcuate recess 5, the wall of which is thereby elastically deformed J, which leads to the preservation of the oil film between the cylindrical roller 4 and the wall of the arcuate recess 5 and to a significant reduction in the wear of its wall. The planetary and rotational movements of the toothed element 2 are performed by a switching device, which ensures that the working fluid flows through the openings 9 or 10 into the chambers 3 and discharges the low-pressure working fluid. , and therefore increasing the durability of the hydraulic device. Claim 1. Hydraulic device containing gearing with two meshed gear elements forming a series of fluid chambers that are installed with the possibility of planetary motion relative to each other, the first of which has internal teeth formed by cylindrical rollers mounted in arcuate grooves with the possibility of displacement in the radial direction and OKpjm, and the second gear element has external teeth, and their number is one less than that of the first a gear element, and a switching device, characterized in that, in order to reduce the wear of the walls of the gear element; internal teeth, on the surface of the latter between the arcuate grooves made around the circumference of the grooves, the number of which is equal to the number of arcuate grooves, while the dimensions of the grooves and cylindrical rollers are selected from the condition of elastic deformation of the walls of the arcuate grooves. It is found that the switching device is made in the form of a valve plate connected to a gear element with external teeth, on the front side of which there are a series of pairs of holes around the circumference, OD1DO of which are constant with connected with high pressure chamber.
