Diese Aufgabe wird erfindungsgeiiiäß dadurch gelöst, daß der Kollektor in geringeiii Abstand von zv/ei hcilbscLiileiiforuiigeii Abdeckhaubeii umgeben ist.This object is achieved according to the invention in that the collector is at a small distance from zv / ei hcilbscLiileiiforuiigeii cover hood is surrounded.

Durch diese Verkleidung wird erreicht, daß eine geringere Strömungsverwirbelung auftritt und die die Bürsten beeinflussenden Strömungslcräfte reduziert werden. Ferner wird die Dampfblasenbildung im Bereich der Bürsten bzv:. zwischen Bürste und Kollektor verringert. This covering ensures that less flow turbulence occurs and the flow forces that influence the brushes are reduced. Furthermore, the formation of vapor bubbles in the area of the brushes or. between brush and collector is reduced.

Ein weiterer >.eg zur Lösung dieser Aufgabe besieht darin, daß der Zollektor eine Cberflächenrauhigkeit von 20 λ* bic 120/1* i/i^besonciope 40 M aufweist. Dadurch wird erreicht, da3 auch bei YerwirbeluiiC» Bildung eines J-'lMssigkeitskeiles oder Kavitation der direkte Kontakt £wisclie:r· Bürsten und Kollektor ojxlialcö.., bleibt.Another> .eg to solve this problem shall examine that the Zollektor bic a Cberflächenrauhigkeit of 20 λ * 120/1 * comprising i / i ^ besonciope 40 M. This ensures that direct contact, ie brushes and collector, remains open even if a fluid wedge is formed or cavitation occurs.

Die angestrebte Oberflächenrauhigkeit des !Kollektors karj_i durch radiales Barsten, durch Pollen öler beiia überdrehen erzeugt werden.The desired surface roughness of the! Collector karj_i by radial bursting, through Pollen oiler beiia overwind can be generated.
