Patentanspruch:Claim: Kollektor für einen Elektromotor zum Antrieb einer Kraftstoffpumpe, welche mit dem Motor in einem gemeinsamen Gehäuse untergebracht ist, dadurch gekennzeichnet, daß der Kollektor (1) eine Oberflächen.rauhigkeit von 20 μ bis 120 μ, bevorzugt von 40 μ, aufweist.Collector for an electric motor to drive a fuel pump, which is connected to the motor in is housed in a common housing, characterized in that the collector (1) a surface roughness of 20 μ to 120 μ, preferably of 40 μ. Die Erfindung bezieht sich auf einen Kollektor für einen Elektromotor zum Antrieb einer Kraftstoffpumpe, welche mit dem Motor in einem gemeinsamen Gehäuse untergebracht ist. Einen Kollektor dieser Art zeigt z. B. die US-PS 23 19 692.The invention relates to a collector for an electric motor for driving a fuel pump, which is housed in a common housing with the motor. A collector like this shows e.g. See, for example, U.S. Patent No. 2,319,692. Bei derartigen Kraftstoffpumpen, die im sogenannten Naßbetrieb arbeiten, tritt ein hoher Bürstenverschleiß auf. Die positive Bürste weist eine bis zu 1Ofache Verschleißrate gegenüber der negativen Bürste auf. Dies wird auf Verwirbelung, Bildung eines Flüssigkeits keils oder Kavitation zwischen Bürste und Kollektor zurückgeführt.In such fuel pumps, which work in so-called wet operation, there is high brush wear on. The positive brush has a wear rate up to 10 times that of the negative brush. This is due to turbulence, the formation of a wedge of liquid, or cavitation between the brush and collector returned. Aufgabe der Erfindung ist es, den Verschleiß der Rürste herabzusetzen.The object of the invention is to reduce the wear and tear on the brush. Diese Aufgabe wird erfindungsgemäß dadurch gelost, daß der Kollektor eine Oberflächenrauhigkeit von 20 μ bis 120 μ, insbesondere 40 μ aufweist. Dadurch wird erreicht, daß auch bei Verwirbelung Erdung eines F üssigkeitskeils oder Kavitation der direkte Kontakt zwischen Bürsten und Kollektor erhalten bleibt.According to the invention, this object is achieved in that the collector has a surface roughness of 20 μ to 120 μ, in particular 40 μ. This will achieves that, even with turbulence, grounding of a liquid wedge or cavitation leads to direct contact is retained between the brushes and the collector. Die angestrebte Oberflächenrauhigkeit des Kollek-,o tors kann durch radiales Bürsten, durch Rollen oder beim Überdrehen erzeugt werden.The desired surface roughness of the collector, o tors can be generated by radial brushing, rolling or over-turning.
