Abstract of the Disclosure: A combined mixing and deflection unit includes a flow conduit for a medium flowing in a given direction. The flow conduit has a bend region, a given direction downstream of the bend region as seen in the given flow direction, and a cross section. A guide configuration is disposed in the bend region for deflecting the flowing medium from a main flow direction. The guide configuration defines a plane aligned approximately parallel to the given direction downstream of the bend region. The guide configuration has openings formed therein being evenly distributed over the cross section of the flow conduit.
