Abstract
A valve device for controlling an exhaust gas flow of an internal combustion engine includes a housing comprising a channel which has the exhaust gas flow therethrough. A shaft is disposed in the housing. The shaft is rotatably mounted about a shaft axis. A flap is connected to the shaft. The flap controls a flow cross section of the channel. The flap comprises two flexurally rigid support plates. The support plates each comprise an outer periphery. An elastic flap body is arranged between the support plates. The elastic flap body comprises an outer periphery which is larger on all sides than the outer periphery of the support plates. A distance between the outer periphery of the elastic flap body and the outer periphery of the support plates is largest in an area of the shaft axis, and smallest at an angle of 90° relative to the shaft axis.
