    Axially spaced and aligned longitudinal distributor grooves are formed in the radially outer surface of a thin-walled tubular valve element in angularly spaced relation to internal grooving of the valve element for conducting pressurized fluid and establishing a torsional coupling in a hydrostatic controller associated with a power steering system. Obliquely orientated bores in the valve housing establish fluid communication between the longitudinal grooves adjacent opposite axial ends of the housing and axial passages in the housing.

    The invention relates to a volumetric hydraulic drive and can be used, for example, in hydrostatic vehicle control devices. .
    Rotary spool valves for a rotary piston machine, a pump or a hydraulic engine, in particular for hydrostatic vehicle control devices, are known, comprising a gear wheel with a rigid body and internal teeth and a gear that has one less than one gear that has a smaller tooth through a limited freedom of rotation the hinge coupling is connected to the shaft of the machine and through the flooded connection - to be installed in the internal opening of the housing the axial direction of the rotary slide, the displacing cells formed between the profiles of the teeth of the tooth colley and the gear wheel through the axial channels made in the body in an amount equal to the number of depressions between the teeth of the gear ring and through the control holes in the inner hole of the body are connected to rotary spool, which on its outer surface has two systems of axially limited distribution longitudinal grooves arranged with the possibility of interaction with a pressure channel and two cylindrical grooves, which are permanently connected to the executive hydraulic lines and runners with the possibility of communication with the drain grooves Yu and 2.
    In known hydraulic distributors, the spool is thick-walled, since the grooves for driving the spool from the gear wheel, made in the inner hole of the spool are in the area of
    longitudinal grooves, which leads to significant dimensions of hydraulic distributors, the complexity of its design and insufficiently high manufacturability.
    The purpose of the invention is to reduce the size, simplify the design and improve the technology of the hydraulic distributor.
    The goal is achieved by c. a rotary gear assembly for a rotary piston machine, pump or hydraulic motor, in particular for hydrostatic vehicle control devices, containing a gear ring with a rigid body and internal teeth and a gear mounted on it with one tooth with outer teeth and a gear wheel. rotation of the hinge coupling is connected to the shaft of the machine and through the lead connection to the one installed in the internal housing bore with the possibility of moving in axially a rotary slide valve, where the pressure cells formed between the profiles of the teeth of the gear ring and the gear wheel through axial channels made in the body in an amount equal to the number of cavities between the teeth of the gear ring and through the control holes entering through the inner hole of the body the spool, which on its outer surface has two systems of axially limited distributive longitudinal grooves arranged with the possibility of interaction with the pressure head channel - and with two cylindrical grooves, which are permanently connected with executive hydraulic lines and are adapted to communicate with the linear grooves, the distribution grooves of both systems are axially axially aligned, and the control openings of one system of distribution longitudinal grooves exiting the axial channels at the entrance to the internal opening of the housing are shifted in the angular direction with respect to the inputs of the control holes of another system of distribution longitudinal grooves extending from the corresponding related axial channels. Both systems of distribution longitudinal grooves are located at the ends of the rotary slide. The rotary slide has a through axial internal profile with longitudinal grooves for communication of the pressure channel with the distribution longitudinal grooves. The control holes are made in the form of drillings, the axes of which are offset relative to the planes passing through the axis of the rotary slide and the axes of the respective axial channels. Axes made in the form of drills of control holes are deflected relative to the plane, perpendicular to the axis of the rotary slide. FIG. 1 shows the structural scheme of the hydraulic distributor; in fig. 2 shows section A-A in FIG. one; in fig. 3 shows a section BB in FIG. 1. Rotary spool valve for rotary piston machine, pump or hydraulic motor, in particular for hydrostatic control devices of automobiles, contains a gear ring 1 with a rigid body 2 and internal teeth 3 and a gear 4c with one tooth less than one tooth 5, which through a hinged coupling 6 having limited freedom of rotation is connected to the shaft 7 of the machine and, through the driving connection, 8 to the housing 10 installed in the inner hole 9 with the possibility of the axial direction of the rotary valve 11, the displacing wheels 12 formed between the profiles of the teeth 3, 5 of the gear ring 1 and the gear wheel 4 through the axial channels 13, made in the body 10 in an amount equal to the number of cavities between the teeth 3 of the gear ring 1 and through the entrance to the inner opening 9 of the housing 1, the control openings 14 and 15 are aligned with a rotary slide valve 1t, which on its outer surface 16 has two systems 17 and 18 axially limited longitudinal grooves 19 and 20, arranged with borrowing with a pressure channel 21 and with two cylindrical grooves 22, which are permanently connected to the executive lines 24, 25, and adapted to communicate with the drain grooves 26 and 27. The distribution longitudinal grooves 19 and 20 of both systems 17 and 18 are made axially axially aligned, and the control openings 14 of one system 17 of the distribution longitudinal grooves 19 at the entrance to the internal opening 9 of the housing 10 are displaced in the angular direction relative to the inputs of the control holes 15 d Another system 18 of distribution longitudinal grooves 20 extending from the respective axial channels 13. Both systems 17 and 18 of the distribution longitudinal grooves 19 and 20 are located at the ends 28 and 29 of the rotary slide valve 11. The rotary slide valve 11 has a through axial internal profile 30 with longitudinal grooves 31 -33 for communication of the pressure channel 21 with the distribution longitudinal grooves 19 and 20. The control holes 14 and 15 are made in the form of bores, the axes of which are offset relative to the planes 34 passing through the axis of the rotary slide 11 and the axes of the respective axial channels 13. The axes of the control holes 14 and 15, made in the form of boreholes, are deflected relative to the plane perpendicular to the axis of the rotary slide 1 1. The pressure channel 21 is connected to the pump 35 and to the groove 26 of the housing O, and the drain grooves 26 and 27 to the tank 36. The displacing cells 12 are connected to the axial channels 13 through the diversion channels 37. The housing 10, the intermediate ring 38, the toothed ring 1 and keys 39 and 40 are bolts 41. The lead connection 8 contains a torsion 42, two driver fingers 43 and 44, the first of which is engaged with the gear wheel 4, and the second with a spool 11. Through finger 44, groove 45 and the screw profile 46 spool 11 is connected to shaft 7 of the machine. . The actuators 24 and 25 are connected to the working cavities 47 and 48 of the servomotor 49. The rotary slide valve works as follows. When the shaft 7 is rotated, the gap between the lead is selected by the finger 44 and the PDS 45, as a result of which the gold pan 11 is displaced axially through the screw profile 46 and also begins to rotate. Together with shaft 7 through a powered coupling. 8, the gear wheel 4 also rotates, rolling around the gear ring 1. At the same time, the displacing cells 12 increase or decrease in the volume. The working fluid from the decreasing cells 12 is displaced through the axial channels 13 into the control holes 15. Depending on the direction of the axial the displacement of the spool 11 (e.g., upwards through the drawing) the grooves 20 connect the control holes 15 through the groove 23 with the hydroline 25 with the working cavity 48 of the servomotor 49, the working cavity 47 of which communicates with the tank 36 through the hydroline 24 and the grooves 22 and 26. Longitudinal can The cables 19, the outlet beyond the end of the housing 10, communicate with the pressure channel 21, however, being displaced in the angular direction relative to the control holes 14, do not participate in the process of controlling the movement of the servomotor 49, but only prevent leakage from the channels 13. The coaxial arrangement of the longitudinal grooves 19 and 20 of both systems 17 and 18 provides the possibility of their simultaneous production by two cutters in one stroke, with one half of the separating operations as compared with the manufacturing process of the known control valves, Except TOGO, despite Kosten slide 11 coaxial with the grooves 19 and 20 allows ztim grooves positioned between the through longitudinal grooves 31-33 for cooperating with the driving pin 44 and the hydraulic fluid passage 21 of the flow channel.
