Feed pump such as exhaust gas supercharger has one pump vane or entire pumpwheel of different material from shaft, namely carbon fiber or graphite

The feed pump (supercharger) has a turbine wheel, a shaft and a pumpwheel with vanes. At least one vane (9), possibly the entire pumpwheel, is made from a different material from the shaft (6). The material in question is carbon fiber or graphite.. Other possibilities are glass fiber and mesophase c...

Zusammenfassung:	The feed pump (supercharger) has a turbine wheel, a shaft and a pumpwheel with vanes. At least one vane (9), possibly the entire pumpwheel, is made from a different material from the shaft (6). The material in question is carbon fiber or graphite.. Other possibilities are glass fiber and mesophase carbon. Die Erfindung betrifft eine Ladepumpe, insbesondere einen Abgasturbolader, für eine Brennkraftmaschine, mit wenigstens einem von den Abgasen beaufschlagten umlaufenden den Abgasen Energie entziehenden Maschinenteil, vorzugsweise einem Turbinenrad sowie einer Welle, die das Maschinenteil mit einem Pumpenflügel aufweisenden Pumpenrad verbindet. Zur Verbesserung des Ansprechverhaltens sind wenigstens die Pumpenflügel des Pumpenrads aus einem anderen Werkstoff als die Welle gefertigt, wobei der Werkstoff Kohlenstoff und/oder Graphit in einer technischen Kohlenstoff- oder Graphitqualität ist.
