Abstract
Abstract A controllable bypass conduit connects the compressor with the exhaust or discharge system and this bypass conduit communicates there in a range of lower pressure on a combustion machine having working chambers formed with a discharge turbo charger. The bypass conduit communicates into a mixing zone of a pulse converter embodied as an underpressure zone.

Claims Analysis
Total Claims: 2
Claim 1
Independent Claim
97 words
In combination, an internal combustion engine forming multiple working chambers, a multi-stage exhaust gas turbocharger having high and low pressure compressor and turbine stages, and a controllable bypass line between the pressure side of the high pressure compressor stage and the exhaust gas system wherein the bypass line empties into a zone of low pressure, between the high and low pressure turbine stages, the pressure of compresed air being higher than exhaust gas pressure when the bypass line branches off behind the high pressure stage of the compressor and before the low pressure stage of the turbine.
