HYDRAULIC MACHINE Russian patent published in 2013 - IPC F03C2/00 F04C2/63 

FIELD: machine building.

SUBSTANCE: hydraulic machine includes the first and the second swinging modules 3, 2. Each module 1, 2 includes annular chamber 3, 4 with inlet and outlet openings and two pairs of pistons 7, 8, each of which is located between pistons of the other pair. Pairs of pistons are rigidly attached to semi-shafts 9, 10 separately and coaxially installed for each pair, each of which is connected to drive shaft 18 by means of general-purpose hinges located around it on various levels of larger and smaller cross-pieces 11, 12 and ring-shaped shaft 13 between them so that poles of hinges coincide. Axes of cross-piece hinges attaching it to the semi-shaft are located at an angle of 90 relative to axes of hinges of the other cross-piece, which attach it to a drive shaft. Axis of shaft 13 is located at an angle to shaft 18 axis. Shaft 20 of module 2 is connected to shaft 20 of module 1 so that axes of hinges of cross-pieces, which are connected to the shaft in module 2, are located at an angle of 45° relative to axes of hinges of cross-pieces, which are connected to shaft 20 in module 1. Outlet openings of modules 1, 2 are interconnected with a common inlet channel. Outlet openings of modules 1, 2 are interconnected with a common inlet channel.

EFFECT: providing uniform supply at designing of a hydraulic machine in the form of a pump or uniform rotation of a hydraulic machine shaft in the form of a hydromotor.
