ABSTRACT:
The pressure wave supercharger of the internal combustion engine has a diaphragm capsule (20) for controlling the supercharge air butterfly (14). The diaphragm (21) of the diaphragm capsule is, in operation, subjected on the butterfly side to the high pressure air in the high pressure air duct (2) and on the other side to the pressure at the protrusion 27 or in the compression pocket (5), via a control pressure line (26; 28). These pressures typical of the process vary with the speed of the cell rotor and control the setting of the supercharge air flap as a function of the speed and loading condition of the engine.
