Abstract

A valve for an exhaust system of an internal combustion engine includes a housing which contains a passage for conducting exhaust gases. In the passage is arranged a closing body with which the passage can be closed. The closing body is fastened in a rotationally fixed manner to a shaft, which is mounted rotatably in the housing, and can be pivoted together with the shaft about the rotation axis of the shaft. The closing body has a partition, which runs perpendicularly to the rotation axis of the shaft, and has a circular outer contour which is sealed off from the housing and divides the passage into a first duct and a second duct. When the closing body is in the closed position both the first and second ducts are closed. When the closing body is in an open position the exhaust gasses can pass through the first and second ducts.
