Abstract
An exhaust gas blow-down valve of a pressure wave supercharger comprising a flap which is connected by a flap lever, a flap shaft and a second lever to a control device responsive to a process pressure of the pressure wave supercharger. In order to avoid deterioration of the scavenging coefficient of the pressure wave supercharger, a restraining screen is provided around part of the periphery of the flap at a distance from it, which restraining screen deflects the exhaust gas flowing out of the flap gap into the desired direction parallel to the axis of the exhaust gas outlet stub pipe.
