Abstract

The pump has a triangular isosceles piston, with slightly curved flanks, and inner bore with internal toothing. The piston moves on an eccentric drive shaft, and meshes with a fixed external toothing. The piston moves in a trochoidal sealed housing with four openings. To operate the pump in left or right direction, there are four additional openings. Alternately, the pump can be operated with only one intake and one discharge in one plane. The unused part of the pump must be provided with openings, to prevent pressure variations. ADVANTAGE - Has few simple parts, to achieve high pressures across large volume flow range.

Description

Die derzeitigen Pumpen kann man in zwei Gruppen einteilen: Pumpen mit Hubkolben, die hohe Drücke bei geringem Volumenstrom erzeugen und Axial- und Radialpumpen, die geringe Drucksteigerungen und hohen Volumenstrom fördern können.The current pumps can be divided into two groups classify: pumps with reciprocating piston, the high pressures generate at low volume flow and axial and Radial pumps, the slight increases in pressure and can promote high volume flow.

Der Nachteil dieser Pumpen ist, daß sie keine hohen Drücke sowohl bei geringem, wie hohem Volumenstrom fördern können.The disadvantage of these pumps is that they are not high Press at both low and high volume flow can promote.

Bekannt sind auch Kühlmittelverdichter nach dem Wankelprinzip von der Firma Ogura-Clutch Co. Ltd, Japan. Bei diesen sind die Einlaßöffnungen nicht in der radialen Lauffläche, sondern in den Seitenwänden angebracht, was eine Verminderung des Medienflusses zur Folge hat. Ebenfalls nicht möglich ist, aufgrund der Einlaßanordnung, der Rücklauf.Coolant compressors are also known after Wankel principle from Ogura-Clutch Co. Ltd, Japan. In these, the inlet openings are not in the radial tread, but in the side walls attached, which is a decrease in media flow has the consequence. Is also not possible due to the inlet arrangement, the return.

Die in Anspruch 1 angegebene Erfindung tritt in die Lücke der bisherigen Pumpenarten.The invention specified in claim 1 occurs the gap of the previous types of pumps.

Die mit dieser Erfindung erzielbaren Vorteile bestehen darin, daß mittels weniger, einfacher Bauteile hohe Drücke über eine große Volumenstromspanne erzeugt werden können. The advantages achievable with this invention consist of using less, easier Components high pressures over a large volume flow range can be generated.  

Eine weitere vorteilhafte Nutzung der Erfindung ist im Anspruch 2 angegeben.Another advantageous use of the invention is specified in claim 2.

Sie besagt, daß sich die Erfindung auch als Arbeitsmaschine verwenden läßt.It says that the invention also Can use work machine.

Die mit der Erfindung erzielbaren Vorteile bestehen darin, mittels weniger, einfacher Bauteile eine energieverlustarme Arbeitsmaschine zu fertigen, die durch ihr Funktionsprinzip und ihre Bauweise einen ruhigen Lauf hat, kleine Baugröße, geringes Gewicht und keine oszillierenden Massen.The advantages achievable with the invention consist of using less, easier Components of a low-loss machine to manufacture, by their operating principle and their design runs smoothly, small size, light weight and none oscillating masses.

Claims (2)

1. Rotationskolbenpumpe zum Fördern von flüssigen, gas- und dampfförmigen Medien, dadurch gekennzeichnet,
daß ein dreieckiger, gleichschenkliger Kolben mit leicht gekrümmten Schenkeln und innerer Bohrung mit Innenverzahnung auf einer exzentrischen Antriebswelle läuft.
Die Innenverzahnung des Kolbens kämmt mit einer festangebrachten Außenverzahnung und beschreibt dadurch eine drehend-exzentrische Bewegung.
Der Kolben läuft in einem trochoidenförmigen, geschlossenen Gehäuse, an dem vier Öffnungen angebracht sind. (A, B, C, D, siehe Zeichnung)
Um die Pumpe im Rechts- oder Linkslauf betreiben zu können, müssen vier weitere, an der Längsachse gespiegelte Öffnungen angebracht werden.
In diesem Fall müssen je nach Laufrichtung vier Öffnungen geschlossen werden.
Möglich ist auch der Betrieb mit nur einer Einlaß- und einer Auslaßöffnung auf einer Ebene, wobei der ungenutzte Teil der Pumpe mit Öffnungen versehen werden muß, um dort Druckunterschiede zu vermeiden.1. Rotary piston pump for conveying liquid, gaseous and vaporous media, characterized in that
that a triangular, isosceles piston with slightly curved legs and inner bore with internal teeth runs on an eccentric drive shaft.
The internal toothing of the piston meshes with a fixed external toothing and thus describes a rotating, eccentric movement.
The piston runs in a trochoidal, closed housing with four openings. (A, B, C, D, see drawing)
In order to be able to operate the pump in clockwise or counterclockwise rotation, four further openings that are mirrored on the longitudinal axis must be made.
In this case, four openings must be closed depending on the direction of travel.
Operation with only one inlet and one outlet opening on one level is also possible, the unused part of the pump having to be provided with openings in order to avoid pressure differences there. 2. Rotationskolbenmaschine nach Anspruch 1, zur Ausnutzung extern vorhandener oder hergestellter Druckdifferenzen.2. Rotary piston machine according to claim 1, for Utilization of externally available or manufactured Pressure differences.
