摘要： An exhaust-gas turbocharger in an internal combustion engine having a compressor in the induction tract and an exhaust-gas turbine in the exhaust-gas line wherein the exhaust-gas turbine has at least two spiral ducts which in each case open into a radial flow inlet passage. Arranged in the radial flow inlet passage is a guide cascade ring which is disposed between two axially delimiting walls. One of the walls is designed to be axially displaceable and adapted to accommodate the vanes of the guide cascade ring. The wall is displaceable axially outward to such an extent that the vanes of the radial guide cascade ring are no longer in contact with the wall and there is a direct, unobstructed flow path to an outflow duct in the exhaust-gas turbine.
