An exhaust gas turbocharger (1) includes a turbine section (2) having a turbine housing (11) and a turbine wheel (4) disposed in the turbine housing (11). The turbine housing (11) defines a fluid inlet (13), a fluid outlet (10), and a volute (9) that receives fluid from the fluid inlet (13). The turbine wheel (4) is disposed in the turbine housing (11) between the volute (9) and the fluid outlet (10). In addition, a radially-extending nozzle (20) is defined between a working surface (34) of an adjustable nozzle ring (32) and a facing surface (11b) of the turbine housing (11). An inner peripheral edge (40) of the nozzle ring (32) is movable in an axial direction relative to an outer peripheral edge (38) of the nozzle ring (32), whereby the nozzle dimensions can be varied. |
