Abstract
A supercharging device is provided for an internal combustion engine that has at least one exhaust gas turbocharger (1, 2) and at least one charge air cooler (LLK) arranged in the outflow of the exhaust gas turbocharger (1, 2). An additional electrically driven compressor (e-booster 6, 7) is arranged downstream of the charge air cooler (LLK) in a bypass (5) to the main flow line (3) to the throttle valve (4) of the internal combustion engine. The main flow line (3) can be closed by a check valve (9) that acts in the direction of a return flow.
