<p>The cone part has a partition wall (3) positioned between an outside cone part (1) and an inside cone part (2) for connecting the inside cone part to the outside cone part in a spaced apart manner to form an interspace between the outside cone part and the inside cone part. An inlet opening (5) is connected to the interspace at an inflow side, and an interspace opening is fixed at an exit side towards an interior part of the outside cone part. A damping element (8) i.e. high-frequency damper, is fixed within the interior of the outside cone part adjacent to the exit side of the interspace.</p> |
