Description

Gegenstand der Erfindung ist eine Drehkolbenpumpe.The invention relates to a rotary lobe pump.

Das Neue der Erfindung wird darin gesehen, daß die Drehkolbenpumpe im Innern eines Elektromotors untergebracht ist oder an ihrem äußeren Umfang auf sonstige Weise angetrieben wird.The novelty of the invention is seen in the fact that the rotary lobe pump is housed inside an electric motor or on its outer periphery is driven in any other way.

Dadurch wird erreicht, daß man auf kleinstem Raum Pumpe und Motor vereinigen kann. Die Drehkolbenpumpe saugt durch ihre Trommelachse das Arbeitsmittel von einer Seite an und läßt es auf der anderen Seite austreten. Ähnliche Pumpenausführungen sind bekannt.This ensures that you have a pump and motor in the smallest of spaces can unite. The rotary lobe pump sucks the working fluid through its drum axis from one side and let it out on the other side. Similar pump designs are known.

In erster Linie soll durch die vorgeschlagene Ausführung die Möglichkeit gegeben werden, die ganze Pumpe in dem Rotor eines Elektromotors aufzunehmen, wie das bei Kreiselpumpen bekannt ist.First and foremost, the proposed design is intended to provide the possibility given to accommodate the whole pump in the rotor of an electric motor, such as which is known from centrifugal pumps.

In der Zeichnung ist eine beispielsweise Ausführungsform veranschaulicht.An example embodiment is illustrated in the drawing.

Fig. i zeigt einen Querschnitt der Pumpe und Fig. 2 einen Längsschnitt nach der Linie A-B. Der Zylinder i, welcher von den Endteilen ii und 12 getragen wird, wird von dem Rotor des Elektromotors 13 oder auf sonstige Weise in Pfeilrichtung in Drehung versetzt. Die Endteile i i und 12, die zur besseren Übersicht aus dem Zylinder gezogen sind, tragen in Zapfenlöchern 8 die Zapfen 4. .eines Schiebers 3 und nehmen dadurch, daß dieser Schieber 4n einem Schlitz 15 der Drehkolbentrommel2 geführt ist, diesen in derselben Drehrichtung mit. Die Endteile ii und 12 und der Trommele sind je für sich gelagert. Das in Drehrichtung vor dem Schieber 3 im Raum 1q. befindliche Arbeitsmittel entweicht durch die Kanalreihe 6, welche in die Bohrung 9 mündet. Hinter dem Schieber 3 entsteht in. gleicher Weise ein Sog, durch den das Arbeitsmittel aus dem axialen Trommelkanal io durch die radialen Kanäle 5 der Trommel :2 in den Arbeitsraum der Pumpe gesaugt wird. Kommt der Schieber in die Lage, in der die Trommel an den Zylinder anliegt, so werden auch die Kanalreihen geschlossen. Sie wirken somit als Ventile. Da sich Zylinder, Trommel und Schieber in einer Richtung drehen, ist die Reibung äußerst gering, wodurch eine höhere Tourenzahl als bei anderen Bauweisen zulässig ist.Fig. I shows a cross section of the pump and Fig. 2 shows a longitudinal section after the line A-B. The cylinder i, which is carried by the end parts ii and 12 is, is from the rotor of the electric motor 13 or in some other way in the direction of the arrow set in rotation. The end parts i i and 12, which for a better overview from the Cylinders are pulled, carry the pins 4. Of a slide in pin holes 8 3 and take the fact that this slide 4n a slot 15 of the rotary piston drum2 is performed, this in the same direction of rotation. The end parts ii and 12 and the Drums are stored separately. That in the direction of rotation in front of the slide 3 in the room 1q. any working fluid escapes through the row of channels 6, which in the bore 9 opens. In the same way, a suction is created behind the slide 3, through which the Working fluid from the axial drum channel io through the radial channels 5 of the drum : 2 is sucked into the working area of the pump. If the slider comes in that the drum is in contact with the cylinder, the rows of channels are also closed. They thus act as valves. Because the cylinder, drum and slide are in one direction turning, the friction is extremely low, which means a higher number of revolutions than with others Construction methods is permitted.
