Abstract

Es ist vorgesehen, daß der Kommutator (2) aus Kohlelamellen (5) gebildet ist und die Kohlebürsten (3) eine in Drehrichtung geriffelte Bürstenlauffläche (6) aufweisen, womit die Verwendung für Brennstoffpumpen für Dieselbrennkraftmaschinen möglich wird.

Figure 00000001
It is provided that the commutator (2) is formed from carbon lamellae (5) and the carbon brushes (3) have a brushed tread (6) corrugated in the direction of rotation, which makes it possible to use them for fuel pumps for diesel engines.
