Exhaust turbocharger with partition wall, having a disc-shaped air gap, between charge-air compressor and exhaust turbine

摘要

For the purpose of cooling the dividing wall (8) between exhaust turbine (3) and charge-air compressor (5) of an exhaust turbocharger, excess charge air flows through a disc-shaped air gap (11) in the partition wall (8) by way of a one-way valve (13) at higher charging pressures and then enters the exhaust system by circumventing the exhaust turbine (3). <IMAGE>
