Abstract
A supercharger comprising a series of parallel rotors disposed within adjacent compartments within the housing of the supercharger. The rotors are designed to physically compress air that is drawn into the system in a gradual, linear manner, rather than in a stepped manner as is common to most conventional superchargers, in order to reduce the amount of energy loss to thermal energy and reduce the stress imparted upon the system via the compression of the air. The rotors comprise a shaft and a helical thread. The diameter of the shaft increases and the pitch of the helical thread decreases from the position of the inlet of the chamber in which the rotor is disposed to the position of the outlet of the chamber in which the rotor is disposed.
