ABSTRACT:
A method and apparatus for compressing and expanding a fluid by passing said fluid through a rotating continuous flow centrifuge wherein said fluid is pressurized by centrifugal action on said fluid by said centrifuge rotor. Said rotor is provided with passageways for said fluid with vanes placed therewithin assuring that the fluid will rotate with said rotor. After compression, said fluid is passed in compressed state through nozzles near the periphery of said rotor with said nozzles oriented to discharge said fluid backward thus reducing the absolute tangential velocity of said fluid. After passing said nozzles, said fluid is passed through inward extending passageways to exit near the rotor center. Cooling is provided for said fluid during said compression, and heating is provided during expansion in said inward extending passages. As an alternate, two rotors may be employed, wherein said fluid is passed to a second rotor for said expansion and for deceleration. Work is required by said fluid during said compression and acceleration, and work is produced by said fluid during said expansion.
