The inventive valve arrangement () also comprises a second valve () for controlling a second gas path () which is separate from the first gas path (), said second valve being mobile between an open position, a closed position and at least one intermediate position independently from the first valve (). The valve arrangement () also comprises a common housing () which contains both valves () and through which the two gas paths () are guided.
