A system for feeding operating gas to a drive () of a motor vehicle, including an atmosphere-side suction inlet () for air under atmospheric pressure, and a feed line () for the operating gas to the drive () under an operating pressure, the operating gas which is conducted to the drive comprising at least part of the air which is sucked in, at least part of the operating gas being conducted through a turbomachine () upstream of the drive () in a first operating type, the turbomachine () comprising an electric generator (), and the turbomachine () being operated in a second operating type as a compressor for the operating gas, an actuable valve arrangement () being provided, at least part of the air which is sucked in being conducted in a turbine direction (T) through the turbomachine () in a first position of the valve arrangement (), and at least part of the air which is sucked in being conducted in a reversed compressor direction (V) through the turbomachine () in a second position of the valve arrangement ().

System for feeding operating gas to a drive of a motor vehicle

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.
