EP 0 611 887 A1 beschreibt ein Motorpumpenaggregat. Dabei ist der Rotor des Motors zwar ein eigenständiges Bauteil, aber mit dem Zylinderblock einer Kolbenpumpe drehfest verbunden.EP 0 611 887 A1 describes a motor pump unit. Here is the rotor of the engine is an independent component, but with the cylinder block one Piston pump non-rotatably connected.

Aggregate dieser Bauart haben den großen Vorteil, daß sie nur einen minimalen Raum beanspruchen. Sie sind aber noch verbesserungsfähig.Units of this type have the great advantage that they only have one occupy minimal space. But there is still room for improvement.

Der Erfindung liegt die Aufgabe zugrunde, ein Motorpumpenaggregat der genannten Bauart noch weiter zu verbessern, insbesondere bezüglich des Fertigungsaufwandes und des Raumbedarfs.The invention has for its object a motor pump unit mentioned design to improve even further, especially with regard to the Manufacturing effort and space requirements.

Diese Aufgabe wird durch die Merkmale von Anspruch 1 gelöst.This object is solved by the features of claim 1.

Demgemäß wird der Rotor des Elektromotors - in einem Axialschnitt gesehen - U-förmig gestaltet. Dabei wird der Steg des U im Bereich der Achse des Aggregats mit einer Innenverzahnung versehen, und die Antriebswelle der Pumpe mit einem entsprechenden Ritzel, so daß Innenverzahnung und Ritzel miteinander kämmen.Accordingly, the rotor of the electric motor is seen in an axial section - U-shaped design. The web of the U is in the area of the axis of the Unit with internal teeth, and the drive shaft of the Pump with a corresponding pinion, so that internal teeth and pinion comb together.

Es kommen verschiedene Arten von Elektromotoren in Betracht, beispielsweise Asynchronmotoren, Reluktanzmotoren oder sogenannte Kurzschlußläufer. There are different types of electric motors for example asynchronous motors, reluctance motors or so-called Squirrel cage.

Es kommen auch die unterschiedlichsten Arten von Pumpen in Betracht. Besonders vorteilhaft läßt sich die Erfindung bei Innenzahnradpumpen anwenden.Different types of pumps can also be considered. The invention can be used particularly advantageously in internal gear pumps apply.

Die Pumpe bildet dabei eine völlig selbständige, autarke Einheit. Sie läßt sich separat herstellen, separat prüfen sowie komplett in den vom Stator des Elektromotors umschlossenen Raum einbauen.The pump forms a completely independent, self-sufficient unit. You can Manufacture separately, check separately and completely in the stator of the Install the electric motor enclosed space.

Dabei ist es möglich, den Rotor des Elektromotors auf dem Gehäuse der Innenzahnradpumpe zu lagern.It is possible to place the rotor of the electric motor on the housing Bear internal gear pump.

Die Erfindung ist anhand der Zeichnungen erläutert. Darin ist im einzelnen folgendes dargestellt:The invention is explained with reference to the drawings. In it is in detail shown the following:

Das Motorpumpenaggregat umfaßt einen Elektromotor 1 mit einem Statorblechpaket 1.1, einer Wicklung 1.2 und einem Rotor 1.3.The motor pump unit comprises an electric motor 1 with a Stator laminated core 1.1, a winding 1.2 and a rotor 1.3.

Es umfaßt ferner eine Innenzahnradpumpe 2. Diese weist ein Ritzel 2.1 auf, ein gegenüber diesem exzentrischen Hohlrad 2.2 sowie einer Ritzelwelle 2.3. Die Ritzelwelle 2.3 ist in Seitenscheiben 2.4, 2.5 gelagert. Im vorliegenden Falle sind Gleitlager 2.4.1, 2.5.1 vorgesehen.It also includes an internal gear pump 2. This has a pinion 2.1, a compared to this eccentric ring gear 2.2 and a pinion shaft 2.3. The pinion shaft 2.3 is mounted in side windows 2.4, 2.5. In the present Cases are provided bearings 2.4.1, 2.5.1.

Die beiden Elemente Motor und Pumpe sind von einem gemeinsamen Gehäuse 3 umschlossen. Im Gehäuse 3 befinden sich ein Zulauf 3.1 sowie ein Auslauf 3.2 für das zu pumpende Medium.The two elements, motor and pump, are common Enclosed housing 3. In the housing 3 there is an inlet 3.1 and an outlet 3.2 for the medium to be pumped.

Gemäß der Erfindung ist der Rotor 1.3 des Motors 1 topfförmig gestaltet. Im vorliegenden Axialschnitt erscheint er U-förmig. Dabei steht die Ritzelwelle 2.3 mit dem Rotor 1.3 über eine Verzahnung in Drehverbindung. Im Steg 1.3.1 des U befindet sich nämlich eine Innenverzahnung, während die Ritzelwelle eine entsprechende Außenverzahnung aufweist. Innenverzahnung und Außenverzahnung kämmen miteinander.According to the invention, the rotor 1.3 of the motor 1 is cup-shaped. in the present axial section, it appears U-shaped. The pinion shaft is 2.3 with the rotor 1.3 via a toothing in rotary connection. In the bridge 1.3.1 the U is namely an internal toothing, while the pinion shaft has a corresponding external toothing. Internal teeth and External teeth mesh with each other.

Es könnte auch eine anderweitige Triebverbindung zwischen dem Rotor 1.3 des Motors 1 und der Ritzelwelle 2.3 hergestellt sein. So ist es denkbar, zwischen diesen beiden nicht nur eine einzige, sondern zwei oder mehrere Verzahnungen mit entsprechenden Drehmoment übertragenden Elementen vorzusehen, so daß eine Übersetzung von der Drehzahl des Rotors zur Ritzelwelle ins Langsame oder ins Schnelle erfolgt.There could also be another drive connection between the rotor 1.3 of the motor 1 and the pinion shaft 2.3. So it is conceivable between these two not just one, but two or more Gears with corresponding torque-transmitting elements provide so that a translation of the speed of the rotor to Pinion shaft in slow or fast.

Der Rotor 1.3 ist auf der Pumpe 2 gelagert, genauer gesagt auf dem Hohlrad 2.3 und den Seitenscheiben 2.4, 2.5.The rotor 1.3 is mounted on the pump 2, more precisely on the ring gear 2.3 and the side windows 2.4, 2.5.
