Patent ID: 7490467

Claim:
A gas flow enhancer for a combustion engine, comprising: a) a housing, enclosing an expansion chamber, having an inlet configured to receive an inlet flow of gas from a gas flow conduit at an inlet pressure; b) a plurality of outer vanes, disposed within the expansion chamber around an outer periphery thereof, configured to produce an outer helical flow of the pressurized gas; c) a plurality of inner vanes, disposed within the expansion chamber in a central portion thereof, configured to produce an inner helical flow of the gas within the central portion, the inner helical flow having a higher velocity and lower pressure than the outer helical flow; d) a flow separator, disposed in the central portion between the inner vanes and the outer vanes, configured to separate the gas flow into outer flow that flows past the outer vanes, and inner flow that flows past the inner vanes; e) an outlet, configured to combine the outer helical flow and the inner helical flow, so as to produce an outlet laminar flow profile having a lower average pressure than the inlet pressure and f) a gas flow enhancer including a flow straightener, disposed within the outlet, configured to diminish the helical flow of the gas.
