Abstract:
1. A charging device for an internal combustion engine, comprising: at least one turbine part, into which a mass stream of exhaust gas flows via an inflow region; a bypass duct branching off from the inflow region for bypassing the at least one turbine part and configured to produce a jet-pump effect; a turbine outlet duct, the bypass duct opening out into the turbine outlet duct at an outlet location in back of the at least one turbine part; a control element for one of opening and closing the bypass duct; the control element is a sleeve-shaped, sliding control valve downstream from a ring bypass duct in the turbine outlet duct, and the control element is continuously movable inside a control path between an open, operating position and a closed, end position in the turbine outlet duct; and wherein the control element has a bevel on its end pointing towards the outlet of the bypass duct, the bevel being complementary to a bevel of a turbine outlet pipe of the housing, and one of (a) sealingly covering the turbine outlet pipe in the end position and (b) being sealed with respect to a housing with the aid of a sealing device.
