Abstract
A wave compression supercharger comprises a rotor mounted for rotation about its longitudinal axis having axially disposed cells formed about its periphery, a shroud surrounding the rotor, a first port plate located between the rotor and an air duct that delivers ambient air to the supercharger rotor and delivers pressurized air to the air intake side of the engine. A second port plate located between the rotor and an exhaust duct carries low pressure gas from the rotor and high pressure engine exhaust gas to the rotor. A hydraulic cylinder has a piston mounted for sliding motion in the cylinder. A mechanical governor driven by the rotor of the supercharger controls a source of pressurized hydraulic fluid that is opened to the cylinder according to variations in the speed of the rotor. The piston is connected to a port plate and delivers a tangential force to the plate causing it to rotate with respect to the longitudinal axis of the rotor. An alternative embodiment causes a cam to be moved by the piston axially into engagement with cam surfaces formed on the port plate. When the cam is moved axially without rotation, the port plate assumes an advanced or retarded position with respect to the rotor.
