Abstract
A device for influencing an exhaust gas flow, in particular for controlling the sound emission in an exhaust branch of an engine, includes a closure member that is movably arranged in the exhaust gas flow. For example, the closure member comprises a flap driven by a motor to move the closure member in the exhaust gas flow. It is thus optionally possible to produce or influence pressure pulsations in the exhaust gas which lead to an audible sound emission. The device according to the invention provides for a so-called “sound design” of a combustion engine. The driving device (the drive motor and a force transmission member to the closure member) is equipped with an active cooling system.
