Abstract

The invention relates to a valve arrangement (2) for an exhaust gas recirculation device of an internal combustion engine, especially in a motor vehicle. Said valve arrangement (2) comprises a first valve (9) which is used to control a first gas path (7) and is mobile between an open position, a closed position, and at least one intermediate position. The inventive valve arrangement (2) also comprises a second valve (10) for controlling a second gas path (8) which is separate from the first gas path (7), said second valve being mobile between an open position, a closed position and at least one intermediate position independently from the first valve (9). The valve arrangement (2) also comprises a common housing (6) which contains both valves (9, 10) and through which the two gas paths (7, 8) are guided.
