The invention relates to hydraulic machine building, in particular to radial piston hydraulic machines.

The purpose of the invention is to simplify the construction and assembly of a gidromashink

The drawing shows a radical piston hydraulic machine with a partial cross-section along the cylinder block.

The proposed hydraulic machine comprises a housing 1, an eccentrically installed cylinder block 2 with piston groups in housing 1, each of which has a piston 3 and a supporting shoe 4 associated with it, which is installed with the ability to interact with the bearing element of the hydraulic machine in the zone of interaction with each piston group of the plate 5 with two protrusions 6 oriented to the axis of the hydraulic machine. The distance B between the projections 6 of the support element - the plate 5 is selected from the relation

a piston group in a plane perpendicular to the longitudinal axis of the tire; e is the eccentricity value. The hydraulic machine has a device for forcing the piston groups during the suction (discharge) stroke; made in the form of a split elastic ring 7, which is installed with the possibility of contact with each support 4, in order to press these shoes against the support element - plate 5. For installing the elastic ring 7 in the interface zone of the piston 3 and the support shoe 4, the transverse through hole 8 is complete, and cylinder block 2 on the rail; "; Noah surface in the area of rasG, - the length of the piston shoe

the position of the elastic ring 7 is provided with a colt1; an evay groove 9 wider than the width of the cross section of the elastic ring 7, which can be in cross section

round, square, rectangular, etc. The cylinder block 2 is mounted on the eccentric 10 of the output shaft, which has a B interface with the cylinder block 2 separated by jumpers 1I

distribution windows 12 (one window is shown in the drawing, the second, not shown, is diametrically opposed), communicated with external hydropines (not shown). Distribution windows 12 during rotation of the eccentric 10 provide the supply and discharge of working fluid, such as to the working chambers 13 of the cylinder block 2.

Radial piston hydraulic machine,

for example, in pump mode, works as follows,

When the output shaft rotates, its eccentric 10 interacts with the TSH1IKDROV 2 unit, which is held from the iipoBopoTa by a pair of diametrically opposite piston groups that received the greatest deviation, and the supporting shoes 4 of which interact with the projections b of the supporting element

according to Mei) e, the rotation of the eccentric 0, in interaction, will be the next pair of piston groups with extracts of the corresponding plates 5,,

As a result of the interaction of the hydromaginous elements, the TsI.T1IIDROV block 2 is associated with a scanning movement, in which the volume of the working chambers 13 of the power supply unit 2 periodically increases and decreases.

When increasing the volume of work;; chambers 13 suction stroke, they are filled with working fluid through the corresponding distribution window 12 of the eccentric 0. More difficult is the guidance of the piston groups in the stroke

i.e. guaranteed by the standard hydroline. Further, the cycles of each of the support shoe 4 correspond,

Estimating the elastic properties of the ring is greatly simplified.

7. When reducing the volume of workers, the design of hydraulic masks and its assembly,

measures 13 - discharge stroke, occurs. This is due to the fact that the ring cocks the working fluid from working-driven driving of the piston groups

13 of the pistons of the piston 3, at the same time, it is split, austere, excluding the liquid through an appropriate rotation of the cylinder block, not the distribution box 12, the eccentric-tO contains other: additional elements,

trick 10 is expelled in the outer besides the protrusions on the plate.
