Abstract

The exhaust flap closes an exhaust duct. An exhaust-gas stream flows directly onto a closure plate which closes the cross section of the exhaust duct at least partially. A flow body is disposed next to the closure plate, onto which the exhaust-gas stream can flow and which takes effect as an actuator for the exhaust flap.
