<p>The turbine has a turbine wheel with multiple rotating blades (2), where an exhaust gas turbine housing limits a flow channel (6) in a region of the rotating blades. The rotating blades include cover band segments (22) at radially outer ends, respectively. An axial gap (56) is provided for injection of sealing air (54) between the cover band-segments and the turbine housing, and the gap connects a supplying ring channel (51) with the flow channel, where the ring channel is subjected to the sealing air. A ring-shaped mixing chamber (53) is provided between the channels.</p> |
