Abstract
A turbine arrangement for controlling a gas flow, in particular for a fuel cell () or for an internal combustion engine (), and a charging device having such a turbine arrangement, is described, in which the gas flow supplied by an inlet () can be controlled by an adjustable slide bushing () covering an entry opening () to form a turbine wheel () arranged in a turbine housing () between a closed position and an open position, such that, in the closed position, the gas flow is throttled and, in the at least partially open position, a controllable proportion of the gas flow drives the turbine wheel () arranged on a shaft () of an electric engine () functioning as a generator for recuperating energy, wherein the slide bushing () releases a wall opening () in the turbine housing () above a predetermined value of the gas flow, such that a bypass channel emerges in order to guide gas flow past the turbine wheel () directly to an outlet opening ().
