ABSTRACT:
An exhaust-gas turbocharger for an internal-combustion engine, the exhaust-gas turbine of which comprises a rotor with an at leash partially diagonal throughflow direction and a spiral guide channel surrounding this and having a mouth region in the form of an angular nozzle, and a variable guide blade cascade with guide blades being arranged in the mouth region. In order to design guide blade cascades with a simpler construction than that of known versions, at the same time with an increase in their operational reliability, according to the invention the guide blades are divided in such a way that they form a divided guide blade cascade with a stationary guide-blade cascade part and with a guide-blade cascade part assigned to this and rotatable concentrically relative to the axis of rotation of the rotor.
