Abstract
In this pressure wave supercharger, the driving belt pulley (19) for the rotor having a freewheel clutch (23) and rolling contact bearings (22) provided on both sides of the same are supported on the rotor shaft (18+20). With respect to the operation of the pressure wave supercharger, this provides the advantages of drive by the engine with constant engine/rotor transmission ratio and of a free-running rotor driven by the gas forces alone.
