Abstract

Für eine Brennkraftmaschine mit mittels Schmieröl versorgten gesonderten Hydraulikkreisen mit jeweils einer Pumpe wird zur Antriebsvereinfachung bei reduziertem Einbauraum vorgeschlagen, anstelle der gesonderten Pumpen eine mittels eines Zwischenläufers zweistufige Innenläufer-Zahnradpumpe zu verwenden.

Figure 00000001
For an internal combustion engine with separate hydraulic circuits supplied with lubricating oil, each with a pump, in order to simplify the drive with a reduced installation space, it is proposed to use a two-stage internal rotor gear pump instead of the separate pumps.
