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.
- 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
- 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
