Abstract
For recirculating the exhaust gas of an internal combustion engine, a recirculation line is provided which leads from the exhaust side to the intake side of the engine. A valve for controlling the recirculation rate is disposed in the line, and in order to prevent the formation of condensates in the line on the exhaust side when the valve is closed, a flushing line is provided which leads from the line segment on the exhaust side to a location point having lower pressure as compared with the exhaust side.
