Abstract

Die Erfindung betrifft ein Motorpumpenaggregat
  • mit einem Elektromotor, umfassend einen Stator und einen Rotor;
  • mit einer Pumpe;
  • die Pumpe ist vom Rotor des Motors konzentrisch umschlossen;
  • der Rotor des Motors ist - in einem Axialschnitt gesehen - U-förmig;
  • der Steg des U ist im Bereich der gemeinsamen Achse mit einer Innenverzahnung versehen;
  • die Welle der Pumpe weist ein Ritzel auf, das mit der Innenverzahnung des Steges des U kämmt;
  • es ist ein Gehäuse vorgesehen, umfassend eine stegseitige Stirnwand und eine gegenüberliegende, anschlussseitige Stirnwand, die die Anschlüsse für das zu fördernde Medium trägt.
Die vorliegende Erfindung ist gekennzeichnet durch wenigstens eines der beiden folgenden Elemente:
  • das Gehäuse ist im Bereich der stegseitigen Stirnwand als Behälter zur Aufnahme von Fördermedium oder zur Aufnahme einer Kühleinrichtung oder zur Aufnahme einer Filtereinrichtung ausgebildet;
  • das Gehäuse ist im Bereich der anschlussseitigen Stirnwand als Ventilblock ausgebildet, umfassend wenigstens eine der folgenden Einrichtungen:
  • ein Wegeventil,
  • ein Sicherheitsventil,
  • ein Druckminderventil,
  • einen Mengenteiler,
  • ein Stromventil,
  • ein Absperrventil,
  • ein Proportionalventil
