TWO-SECTION ROLLER-BLADE HYDRAULIC MACHINE Russian patent published in 1995 - IPC

FIELD: mechanical engineering. SUBSTANCE: hydraulic machine has housing with grooves and bearings, ring working chambers with passageways for supplying and discharging fluid, contactors with shifted recesses, rotors with blades, and gear mechanism for synchronization of rotation of the contactors and rotors. The contactors have cogs. The rotors have alternative parts of tangential areas and gear sectors positioned inside the ring working chambers. The blades are made up as two symmetry members mounted on the pins of the rotors and springs for permitting axial- radial movement. The bearings of the contactors are made up as end bushings and middle detachable bushing. The pressing springs are mounted on the pins of the rotor. Openings are made at the buts between the tangential areas of blades and rotors. The sealing pins are received in the openings. EFFECT: enhanced efficiency. 3 cl, 7 dwg
