Abstract

Die Erfindung betrifft eine sichellose Innenzahnradpumpe;

  • mit einem innenverzahnten Hohlrad;
  • mit einem Ritzel, das mit dem Hohlrad kämmt;
  • Ritzel und Hohlrad sind in einem Gehäuse drehbar gelagert, das einen Sauganschluß und einen Druckanschluß aufweist;
  • das Hohlrad weist radiale Durchbrüche auf, die jeweils eine leitende Verbindung zwischen dem Zahngrund und der Mantelfläche des Hohlrades herstellen;
  • zwischen den tragenden Flanken der Zähne des Hohlrades oder der Zähne des Ritzels und den Radialbohrungen des Hohlrades sind leitende Verbindungen hergestellt.
    • Figure 00000001
    The invention relates to a sickle-free internal gear pump;
  • with an internally toothed ring gear;
  • with a pinion that meshes with the ring gear;
  • Pinion and ring gear are rotatably mounted in a housing which has a suction connection and a pressure connection;
  • the ring gear has radial openings, each of which creates a conductive connection between the tooth base and the outer surface of the ring gear;
  • Conductive connections are made between the supporting flanks of the teeth of the ring gear or the teeth of the pinion and the radial bores of the ring gear.
