Abstract
The present invention relates to an improved apparatus used for moving gases or air in a single stage for the purposes of either causing a vacuum upstream as in vacuum pumps or high-pressure downstream as in industrial blowers, turbochargers for automotive engines, ducted fan propulsion devices, and compressors for gas turbines. In this improved concept, two matching sets of rotor vanes are paired, rotating in the same direction, without a stator between them, having continuous and progressive pitch angles, the same number of blades, and designed to complement each other. Therefore, the turbo apparatus can yield extreme high-pressure ratios at high flow rates.
