Abstract

A charging device (supercharger) for internal combustion engines, having at least one turbine part. A mass stream of exhaust gas flows into this via an inflow region, from which a bypass duct branches off for bypassing the at least one turbine part. The bypass duct opens out into a turbine outlet duct at an outlet location in back of the turbine part. The bypass duct is opened or closed either by a first control element situated in the inflow region at the inlet of the bypass duct or by a second control element at the outlet of the bypass duct leading into the turbine outlet duct.
