HYDRAULIC MACHINE Russian patent published in 1994 - IPC

FIELD: hydraulic engineering. SUBSTANCE: in operation of the machine rotation of shaft 4 and carrier 11 results in rotation slide 5. If displacement of axis of bearing supports 22,23 of cylinder bank 17 with respect to axis of bearings 3 of shaft 4 is absent then slide 5 does not move with respect to carrier 11 and cylinder bank 17 and a working volume of the machine is equal to zero. When axis of supports 22,23 of cylinder bank 17 is sifted relatively axis of shaft 4 under the action of hydraulic cylinders 28,29 slide 5 moves relatively carrier 11 and cylinder bank 17 in the radial direction resulting in changing the volume of working chambers. The working volume of the machine depends on a magnitude of displacement of axes of bearing supports 22,23 relatively shaft 4. EFFECT: expanded functional capability by providing controlling working volume of the machine. 2 cl, 13 dwg
