Abstract
Abstract A method and apparatus for the pressurizing of fluids wherein a rotor is rotated on a shaft and the rotor is provided with an entry for the fluid at center, a pressurizing cavity with vanes, nozzles discharging the fluid forward, a vortex cavity for pressurizing the fluid, and exit means for passing the fluid from the rotor. Usually a casing is provided for collecting the pressurized fluid with an exit for delivery. The pressurizer can be used to pressurize either liquids or gases. The exit means from the rotor may be nozzles directed to discharge the fluid, or they may be other means for reclaiming part of the kinetic energy of the leaving fluid.

Claims Analysis
Total Claims: 4
Claim 1
Independent Claim
166 words
A fluid pressurizer comprising a shaft mounted for rotation, a rotor mounted on said shaft so as to rotate therewith, a casing enclosing the rotor said rotor having an entry for a fluid to be pressurized near its center, said rotor having a first cavity concentric with said shaft communicating with said entry for passage of said fluid and having a set of vanes, said first cavity having a set of feeder nozzles for discharging said fluid in a direction that is forwardly and in the direction of rotation into a second cavity, said second cavity being a radially outward cavity concentric with said shaft, said fluid being pressurized within said second cavity by centrifugal force acting on said fluid, said fluid being then discharged from said second cavity into the casing through a set of exit openings located near to the outer radius of said second cavity, said fluid pressurizer having an outlet through which the fluid in the casing may flow from the pressurizer.
Claim 2
Dependent Claim
166 words
A fluid pressurizer comprising a shaft mounted for rotation, a rotor mounted on said shaft so as to rotate therewith, a casing enclosing the rotor said rotor having an entry for a fluid to be pressurized near its center, said rotor having a first cavity concentric with said shaft communicating with said entry for passage of said fluid and having a set of vanes, said first cavity having a set of feeder nozzles for discharging said fluid in a direction that is forwardly and in the direction of rotation into a second cavity, said second cavity being a radially outward cavity concentric with said shaft, said fluid being pressurized within said second cavity by centrifugal force acting on said fluid, said fluid being then discharged from said second cavity into the casing through a set of exit openings located near to the outer radius of said second cavity, said fluid pressurizer having an outlet through which the fluid in the casing may flow from the pressurizer.
Claim 3
Dependent Claim
29 words
The pressurizer of claim 1 wherein said set of exit openings are a set of nozzles sized and shaped to accelerate said fluid being discharged from said second cavity.
Claim 4
Dependent Claim
32 words
The pressurizer of claim 1 wherein said set of exit openings are a set of nozzles arranged to discharge said fluid in a direction that is away from the direction of rotation.
