Abstract
In a pressure wave charger for the supercharging of internal combustion machines, the cell rotor consists of a ceramic material and is driven by the force of the gases of the internal combustion machine. The cell rotor is located between the air housing and the gas housing. It is bearingly supported on a rotor shaft, which in turn is supported on an axle. Both the axle and the rotor shaft are projecting from the air housing in a manner such that the distance of the cell rotor to the bearing symmetry is minimized. By spring based means a frictional connection is established between the cell rotor and the rotor shaft. The rotor shaft is further protected by a thermal protection device.
