ABSTRACT:
In a gas dynamic pressure wave supercharger for vehicle internal combustion engines, at least one of the two mutually facing end surfaces of the rotor and the air casing is made convex on the air casing side in order to maintain an axial clearance which increases radially from the inside to the outside. On the gas casing side, at least one of the two mutually facing end surfaces of the rotor and the gas casing is made concave in order to maintain an axial clearance which decreases in the cold condition radially from the inside to the outside. The concave or convex end surfaces can be formed as truncated cone surfaces or as spherical surfaces. By the appropriate shaping of the rotor and casing end surfaces, the thermal expansion and rotor vibrations are compensated and the supercharger can run with a small axial clearance and good efficiency.
