Abstract
A method and apparatus for the pressurizing of fluids within a rotating rotor wherein a fluid enters the rotor near center, is first pressurized by centrifugal force with initial acceleration and is then further accelerated and pressurized within a circular cavity in a free vortex. The fluid then leaves the circular cavity via openings at periphery and is passed inwardly toward rotor center via passages, and discharged via opening near rotor center. Fluids may be gases or liquids. The device can be used either as a pump, a compressor, or a turbine as desired.
Claims2
A fluid pressurizer comprising:
- a. a shaft mounted for rotation;
- b. a rotor mounted on said shaft to rotate therewith, said rotor being provided with an entry for a fluid to be pressurized, said entry communicating with a pressurizing cavity extending outwardly from the rotor center, said pressurizing cavity communicating with a set of feeder nozzles for passing a fluid forwardly in the direction of rotation into a free vortex cavity of circular configuration and transverse to the rotor axis, said free vortex cavity communicating near its periphery with exit openings to allow the discharge of the fluid from the free vortex cavity.
