    The hydraulic machine consists of a fixedly mounted in the housing 1 of a block of cylinders 2, in cylindrical drills 3 of which pistons 4 are slidably connected by connecting rods 5 with a swinging node 6. The swinging node 6 consists of a support 7 and an inclined disk 8 with an inclined surface 9 perpendicular to the axis 10 swinging node 6.
    The inclined surface 9 forms an acute angle about with the axis 11 of the fixed cylinder block. Swing node 6 is equipped with a drive pin 12 located in the disk 13 of the gear 14 mounted on bearings 15 roller type, engaging with the side gear wheel 16 connected to the drive shaft 17 of the motor drive (not shown). The inclined disk 8 is rigidly connected to the housing 1, and the latter is provided with a cover 18.
    The central part 19 of the inclined disk 8 is provided with a spherical bearing 20 with a fixed spherical pin 21 installed inside it, and the central angle p is greater than 180 °, for example, it can be equal to 250 °. The spherical pin 21 is rigidly connected with the axle 22, installed along the axis 11 of the cylinder block 2 and fixed in its center 23.
    The drive pin 12 is located in a spherical hinge 24 mounted in a bearing 25 enclosed in a disk 13 of a gear 14, and oriented along an axis 10 perpendicular to the inclined surface 9 of an inclined disk 8. The bearing 25, in which the spherical hinge 24 is located, is eccentric and provided the device 26 for adjusting the angle of position relative to the disk 13. The device 26 for adjusting the angle of position of the eccentric bearing 25 may, for example, have eight holes 27, 1514246
    bounded at its periphery, then when installing the mounting bolts 28 in the drill 27, you can choose with an accuracy of 1/8 turn the angular position of the spherical hinge 24 in the bearing 25 of the disk 13. The eccentricity of the bearing 25 allows it to rotate from one angular position to another around the axis 11 change the eccentricity of this axis 11 with respect to the spherical hinge 24, which leads to a change in the inclination angle The inclined disk 8 is provided with a side connecting rod 29, the spherical ends 30 and 31 of which are pivotally connected to the disk 8 and the housing 1 for rigid connection with the latter, which prevents rotation of the disk 8 during its zigzag movement relative to the support of the 7-swinging node 6. Inclined disk 8 can be provided with a pair of 32 bevel gears, one of which, for example, gear wheel 33, is mounted on the periphery of the swash plate 8, and the other, for example gear wheel 34, is rigidly connected to housing 1 and is oriented around axis 11. When the gear wheel rotates 14, a fixed gear 34 prevents movement of the movable gear 33, while the inclined disk 8 of the rocking assembly 6 is blocked from rotation.
    Rotational machine is equipped with an oil pump 35, made in the form of fixed drilling 36 in the cylinder block 2, which has elements 37 of the reciprocating movement, containing a piston 38 with a thrust 39, in which a through channel 40 is made. There is a check valve 41 in the oil pump 35. The oil pump 35 is installed between the front surface 42 of the swash plate 8> and the opposite surface 43 of the fixed cylinder block 2. During the swinging movement of the swivel disk 8, the piston 38 is reported to have a reciprocating 39 through the thrust 39 move Any external lubrication pump (those shown) through the opening 44 in the oil pump 35, check valve 41 and through channel 40 in the piston 38 and the rod 39 enters the channel 45 of the swash plate 8 to the spherical bearing 20. The lubricant can be lubricated either hydrostatics, or in hydrodynamics, depending on the cases of displacement.
    The axle shaft 22, mounted in the center 23 of the cylinder block 2, is integral with a spherical pin 21. The semi-axle 22 and pin 21 are provided with a central channel 46, made along the axis 11 with a fork in the axle 21 into several radial channels 47, extending to the periphery in the annular zone 48 , for lubrication of a spherical bearing 20. The central channel 46. is connected to a source of lubricant (not shown).
    The body 1 of the machine has a flange of $ 4 and a counter flange 50 connected to the drive shaft 17, coaxially located about the axis 11 of the fixed cylinder block 2. The relative orientation of the flange 49 relative to the counter flange 50 allows any position of the drive shaft 17. Axis 51, coaxial * ny with axis 11 and rigidly connected with the eccentric bearing 25 of the disk 13 of the gear 14, can serve to drive the tachometer or can also be used to supply lubrication to the spherical hinge 24 of the driving pin 12.
    The drive pin 12 may be made in the form of a semi-axis. It is associated with a spherical pin 21, mounted on the cover 18 and is located along the axis 11 of the fixed cylinder block 2. The semi-axle 22 and the pin 12 are equipped with nuts 52 and 53, respectively. Acting on the nut. 52, it is possible to adjust the magnitude of the thrust force of the cylinder block 2, perceived by the semi-axis 22. The nut 53 allows fixing the pin 12 relative to the housing 1. The cover 18 is equipped with a means 54 for preloading the spherical bearing 20 and bearings 55 and 56 roller type. The tool 54 pre-loading can be made in the form of a combined adjustment gasket installed between the cover 18 and the housing 1, the thickness of which is selected depending on the required preliminary loads. In addition, the tool 54 pre-loading can be made in the form of a coaxial annular hydraulic cylinder 57 preloading bearings 55 and 56 roller type, located between the cover 18 and the bearing 55 roller type. The hydraulic cylinder 57 is designed as an annular groove in the lid 18. Inside the hydro7

    Cylinder 57, a slide piston 58. The cavity 59 formed between the ring bottom 60 and the piston 58 is fed through ·· orifice 61 with the working fluid under pressure from an external pressure source (not shown). Thus, the force acting on the bearings 55 and 56 is adjusted.
    Support 7 swinging node 6. can be made integral in the form of two parts 62 and 63, the supporting surfaces 64 and 65 of which have different angles of inclination, but, at the same time, the supporting surfaces are perpendicular to the axis 66, which forms with the axis 11 an angle equal to half the angle between the axis 10 of the swinging assembly 6 and the axis 11 of the cylinder block 2, i.e. the angle is equal to They are interconnected by means of fastening 67, for example, screws evenly distributed in a circle around the axis 66. When assembling the rocking assembly 6 having a composite support 7, determine the stroke length of the pistons 4, and then fix the parts 62 and 63. The maximum stroke of the pistons 4 corresponds The position shown in FIG. 6, the zero stroke position is achieved by moving the part 63 through 180 ° relative to the part 62 so that the surface 68 opposite to the supporting surface 65 is perpendicular to the axis 11 of the cylinder 2 (FIG. 7). It is possible to use a continuous monitoring device with an external control of the position of both parts 62 and 63 (not shown).
    The axle shaft 22 can be mounted in axial drilling of the 69 block with cylinder 2 with a gap 70 and provided with a swing 71 on the side of the rocking assembly 6, supported on the cylinder block 2, and on the other hand with a thread 72 under the nut 52. In addition, the 22 half with a spherical pin 21 and pin 12 can be made in one piece ^ with the formation of a single rigid shaft.
    Case I can be made in the form of two parts 73 and 74, provided with annular flanges, 75 and 76, located concentric with the axis 11 of the cylinder block 2, can change its angular position. Thus, you can choose the angular position of the drive shaft 17 relative to the axis 11.
    Rotary machine in pump mode works as follows.
    The drive shaft 17 using the side gear 16 and gear 14 causes the support 7 of the rocking assembly 6 to rotate. The axis 10 of the rocking assembly 6 is a generator that describes the conical surface around the axis 11 of the stationary cylinder block 2. The value of the angle at the apex can be adjusted as a result careful selection of the angular position of the finger 12 in the eccentric bearing 25.
    Since the inclined disk 8 is blocked from rotation by means of a side connecting rod 29 or a pair of 32 bevel gears 33 and 34, it describes around the fixed axis 11 a swinging motion that affects the pistons 4 and informs them of a reciprocating movement in cylindrical holes 3 of the cylinder block 2. The force caused by the pistons 4 due to the pressure of the injected fluid tends to pull the Inclined disk 8 out of the fixed spherical pin 21. The spherical bearing 20, which closes around the fixed semi-axis 22, counteracts this in Giving, causing friction mainly in the annular zone 48, therefore lubricant is supplied to it through channels 47. The forces perceived by the inclined disk 8 are transmitted to the spherical pin 21, which transfers them through the semi-axis 22 directly to the fixed cylinder block 2. In other words, the efforts , developed by the pressure of the pistons 4 on the inclined disk 8, are perceived directly by the opposing force arising from the action of the cylinder block 2 on the semi-axle 22 liters and they are not transmitted to the pump housing 1. Consequently, this housing 1 can be lightened, which leads to savings in metal. Even with the increase. The discharge pressure of the fluid pumped by the pistons 4 has no effect on the forces that the housing 1 is subjected to.
