TWO-SHAFT MULTI-STAGE RADIAL-FLOW SPECIAL-PURPOSE MACHINE Russian patent published in 2010 - IPC F04D1/06 F04D15/00 F04D17/12 

FIELD: engines and pumps.

SUBSTANCE: proposed machine comprises housing 1, intake and discharge branch pipes 10-13, two parallel shafts 2, 3 with adjacent rotor stages 4-7 and intercommunicated by diffuser channels 9 with their outlets making inlets of adjacent stages, and common drive for said shafts 2, 3. Rotors stages 4-7 of said shafts 2, 3 are made from porous plate 8 an plate valve 14 fitted on shaft 2 or 3 to move there along by means of, for example mechanical or magnetic control device. Valves 14 open inlet into diffuser channel 9 of the next stage varying flow direction of pumped fluid to opposite one without cutout o the motor. Hollow shafts 2, 3 can feed sorbent via radial holes into porous plates 8.

EFFECT: multifunction machine to be used as pump or compressor, wet gas cleaner, heat exchanger, heat regenerator, higher efficiency and simple design.
