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.
The invention relates to a motor pump unit
  • with an electric motor, comprising a stator and a rotor;
  • with a pump;
  • the pump is concentrically enclosed by the motor rotor;
  • the rotor of the motor - seen in an axial section - is U-shaped;
  • the web of the U is provided with internal teeth in the area of the common axis;
  • the shaft of the pump has a pinion which meshes with the internal toothing of the web of the U;
  • a housing is provided, comprising a web-side end wall and an opposite, connection-side end wall which carries the connections for the medium to be conveyed.

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
Figure 00000001
The present invention is characterized by at least one of the following two elements:
  • the housing is designed in the region of the web-side end wall as a container for receiving the conveyed medium or for receiving a cooling device or for receiving a filter device;
  • the housing is designed in the region of the connection-side end wall as a valve block, comprising at least one of the following devices:
  • a directional valve,
  • a safety valve,
  • a pressure reducing valve,
  • a flow divider,
  • a flow valve,
  • a shut-off valve,
  • a proportional valve
