CONTROLLED AXIAL-PISTON HYDRAULIC MACHINE Russian patent published in 2019 - IPC F04B1/22 

FIELD: machine building.

SUBSTANCE: invention relates to hydraulic machine building and can be used in volumetric hydraulic drive of running and process equipment of process machines. Adjustable axial-piston hydraulic machine consists of a housing in which a cylinder block is rigidly connected to the shaft by means of a splined joint. Piston mechanisms are arranged in cylindrical bores of cylinder block to make boreholes with borings, which are hydraulically communicated via holes in cylinder block with distributor chambers, which, in their turn, are connected with hydraulic lines of hydraulic machine. Cavities of the distributor are separated by bridges. On the other side piston mechanisms rest on support discs. On the support discs identical gear rims are installed, which form identical gears connected to the control roller fixed in the hydraulic machine body.

EFFECT: enlarging functional capabilities of axial-piston hydraulic machine due to possibility of smooth control of angular speed in motor mode or liquid flow rate in pump mode without occurrence of hydraulic shocks in under-piston chambers.
