An exhaust-gas turbocharger (1) having a compressor (2); a turbine (5) which has a turbine wheel (6) with a radial flow region (11) and a semi-axial flow region (12) and which has a turbine housing (7) which has a spiral arrangement (9), surrounding the turbine wheel (6) at its outer circumference (8), for supplied exhaust gas; and a guide grate (10) for supplying exhaust gas to the turbine wheel (6). The guide grate (10) has a guide ring (13), which is axially movable in the charger axial direction (L) and is assigned to the radial flow region (11), and a closure sleeve (14), which is axially movable in the charger axial direction (L) and which is assigned to the semi-axial flow region (12). |
