DAMMING DEVICE OF AN INTERNAL COMBUSTION ENGINE

摘要

The invention relates to a damming device for an internal combustion engine, comprising at least one exhaust gas piping (18), through which exhaust gas of the internal combustion engine can flow, and at least one flap element (10), which is connected to an actuating device of the damming device by means of a coupling element and which can be adjusted by means of the actuating device between an open position that at least partially unblocks a flow cross-section of the exhaust gas piping (18) and at least one damming position that narrows the flow cross-section relative to the open position, wherein the flap element (10) can be adjusted from the damming position to the open position when the coupling element fails as a result of a pressure load on the flap element (10) due to the exhaust gas.
