A device and a method are for closing a flow duct. The device has a valve which may be pivoted between an open position and a closed position by a valve shaft and has at least one valve wing which, in the closed position, rests against a sealing contour provided in the flow duct. The valve wing is of elastic configuration and the sealing contour or the valve wing is arranged such that first of all a region, at a distance from the valve shaft in the radial direction, of the valve wing comes into contact with the sealing contour when the valve wing is being brought into contact with the sealing contour, and that, during further pivoting of the valve shaft, the valve wing is deformed to such an extent that it rests substantially completely against the sealing contour.
A device for closing a flow duct, at least one sealing contour arranged in the flow duct, comprising:
A pivotable valve arranged as at least one of a shut-off and a throttle valve, comprising:
A method for closing a flow duct by a device that includes a valve pivotable between an open position and a closed position by a valve shaft, the valve including at least one elastically-configured valve wing that, in a closed position, rests against a sealing contour arranged in the flow duct to completely shut off the flow duct, comprising:
