The invention relates to a turbine comprising a turbine housing defining a volute having a substantially annular outlet opening, a turbine wheel, and an adjusting ring, rotatable about the turbine axis, which is arranged in the turbine housing radially between the volute and the turbine wheel, wherein the adjusting ring comprises a flow channel between a radially outer first peripheral opening and a radially inner second peripheral opening, and wherein the outlet opening is fluidically coupled to the turbine wheel by the flow channel. The outlet opening and the first peripheral opening have a path, variable in the axial direction, so that during a rotation of the adjusting ring, the outlet opening and the first peripheral opening are adjusted relative to each other in such a way that an overflow cross section between the outlet opening and the first peripheral opening is variably changeable.

Turbine with adjusting ring

A compressor with a compressor housing in which a compressor wheel is arranged. The compressor additionally includes a cartridge which is arranged in the compressor housing in the area of a compressor inlet. The cartridge is designed to variably change the cross section of the compressor inlet.

Compressor with variable compressor inlet

A charging apparatus () for a combustion engine, having a compressor () which has a compressor housing () in which a compressor wheel () is arranged, the compressor wheel being mounted on one end () of a rotor shaft (), and which has a compressor housing rear wall (); and having an electric motor () which has a stator winding () which surrounds a magnet (), which is arranged on the rotor shaft (), on the outside. The stator winding () is an iron-free stator winding, and the electric motor () is a brushless DC motor.

Charging apparatus for a combustion engine

The invention relates to a regulating method for a turbocharger () with a turbine () which has a variable turbine geometry (VTG) provided with adjustable guide blades (), having the following method steps: a) closing the guide blades () of the variable turbine geometry (VTG), as a function of the present operating point of the internal combustion engine which is turbocharged by means of the turbocharged (), to the maximum possible closing position of the guide blades () for said operating point, and b) regulating the charge pressure (P) by adjusting the position of the guide blades () in a closed regulating loop.
