Abstract
A device for influencing an exhaust gas flow, in particular for controlling sound emission in an exhaust branch of an engine, has a closure member that is driven by a motor in the exhaust pipe. The closure member produces pressure pulsations in the exhaust gas, so that a so-called “sound design” is possible. A force-transmitting, thermal decoupling member is integrated into a force transmission member located between the drive motor and the closure member to interrupt the heat transfer between the closure member and the drive motor.
