摘要

An exhaust gas turbocharger for a combustion engine comprises two turbochargers, a compressor and two gas-regulating flaps (6,18) on the same shaft (4). Both flaps work against sealing faces and the relative sizes of the flow direction and against flow direction surface of the two flaps are opposite to one another.
