Abstract: An exhaust-gas turbocharger turbine of an internal combustion engine is provided with a spiral guide passage arranged in a turbine housing, a turbine impeller, a flow gap be ween the guide passage and the turbine impeller, and guide blades forming a guide cascade. The guide cascade with the guide blades projects axially from a support, arranged so as to be displaceable in the axial direction in the turbine housing, in such a way that the guide blades, in normal operation, are mounted in recesses of a housing wall part of the turbine housing, the recesses, in the form of a female piece, forming a mating profile shape for the guide blades. In braking operation of the internal combustion engine, the guide blades project into the flow gap during an axial displacement of the support. The device with actuation for the braking operation can be fitted as a complete module into the turbine spiral.

Abstract: An exhaust gas turbine portion of a vehicle engine turbocharger is provided with at least one variable guide-blade cascade with guide blades in a nozzle opening to the turbocharger rotor for effectively changing the cross section of the exhaust flow to the rotor wherein the angle of the guide blades is selectively settable by an adjusting device. The width dimension of the gap between the ends of the guide-blade cascade and the casing wall defining the nozzle is adjustable between a substantially zero gap dimension and a maximum gap dimension.
