Internal combustion engine with compound air compression

摘要

A rotary air compressor with a housing forming an epitrochoidal chamber in which a multilobed rotor with a ring gear eccentrically rotates on an internal central gear in the housing, the rotor dividing the chamber into multiple subchambers of changing volume as the rotor rotates, the chamber having intake ports of variable size opening to change the quantity of gas that is compressible and outlet ports having spring biased plunger valves to prevent flow of discharged compressed air back into the compressor.
