Abstract (en)

The blower group has a compressor (2), which supplies air to the motor cylinders. The compressor has an impeller (21) rotating about an axle (A) to compress the air. A turbine drives the impeller and is driven by exhaust gases from the cylinders. A diffuser (4) connected to the compressor outlet (23) reduces the flow speed of the compressed air. The compressor outlet is arranged at a higher level, on or above the compressor axle. An Independent claim is included for a large diesel motor incorporating the blower group.

Abstract (de)

Es wird eine Aufladegruppe für einen Grossdieselmotor vorgeschlagen, mit einem Verdichter (2) zum Verdichten von Luft, die als Spülluft Zylindern (11) des Grossdieselmotors (10) zugeführt wird, welcher Verdichter (2) einen Auslass (23) für die verdichtete Luft sowie ein auf einer Achse (A) angeordnetes Laufrad (21) zum Verdichten der Luft aufweist, mit einer Turbine (3) zum Antreiben des Laufrads (21) des Verdichters (2), wobei die Turbine (3) mit Abgasen aus den Zylindern (11) antreibbar ist, und mit einem Diffusor (4) zum Reduzieren der Strömungsgeschwindigkeit der verdichteten Luft, welcher mit dem Auslass (23) des Verdichters (2) verbunden ist, wobei der Auslass (23) des Verdichters (2) auf einem Höhenniveau angeordnet ist, welches bezüglich der normalen Gebrauchslage auf oder oberhalb der Achse (A) des Verdichters (2) liegt. <IMAGE>
