description The invention relates to a flap device for controlling a gas flow through a pipe, in particular to an exhaust gas flap device for an exhaust train of a motor vehicle, comprising at least one flap which is arranged in a flap housing, in particular in a tubular flap housing, rotatable, in particular rotatable by a drive unit, about an axis of rotation of a flap shaft between an open position and a closed position, with a spring means being provided which, on a rotation of the flap from the open position into the closed position, tangentially and/or radially elastically loads the flap shaft at the latest in the closed position of the flap, and with at least one section of the spring means being directly or indirectly rotationally fixedly connected to the flap housing with respect to a rotation about the axis of rotation. 本发明涉及一种风门片装置,用于控制通过管道的气流,尤其涉及一种用于机动车的排气系统的排气风门片装置,其包括至少一个风门片,该风门片布置在风门片壳体中,尤其是布置在管状风门片壳体中,该风门片可绕着风门片轴的旋转轴线在打开位置和关闭位置之间旋转,特别是通过驱动单元可旋转,并且风门片装置设有弹簧装置,在风门片从打开位置旋转到关闭位置时,最迟在风门片的关闭位置处该弹簧装置切线方向和/或径向弹性
