Abstract

The pump has a circular cylindrical casing (6) with inlet and outlet channels (12). The casing contains a rotor (7) with cylinder channels (8) in a cruciform arrangement. There are control apertures at the outer edge of these channels. At one side of the rotor there is an eccentric rotor disc (9) with two roller pistons (10) in the channels (8). When the rotor rotates, the cylinder apertures (11) run across the inlet and outlet channels, casing the pistons to cross the middle point of the cylinder channels from one side to the other.

Description

Bei der Erfindung handelt es sich um eine selbststeuernde Rotationskolbenpumpe mit konstantem Hub, die den Ein- und Auslaß ohne besondere Hilfsmittel wie Ventile und dergleichen selbst steuert. Die Erfindung kann als Pumpe zum Saugen und Drücken gefertigt sein.The invention is a self-steering Rotary piston pump with constant stroke, which the inlet and Outlet without special aids such as valves and the like controls itself. The invention can be used as a pump for suction and Be made.

Eine Rotationspumpe nach der Erfindung läuft vollständig ausgeglichen und läßt hohe Drehzahlen zu. Hierbei wird durch die Zentrifugalkraft das Medium nach außen geschleudert und zusätzlich von Kolben aus Zylinderkanälen herausgedrückt. Die Kolben können auf einer Achse starr oder drehbar als Rollkolben ausgebildet sein, wobei sie in den Zylinderkanälen reibungslos ablaufen. Eine Rotorscheibe ist in einem Gehäusedeckel so eingelassen, daß beide zusammen zur Zylinderseite des Rotors eine ebene Fläche bilden. Hierbei ist die Rotorscheibe exzentrisch seitlich zum Rotor angebracht und greift mit den Kolben in die Zylinderkanäle.A rotary pump according to the invention runs completely balanced and allows high speeds. Here is by the centrifugal force flung the medium outwards and additionally pushed out of cylinder channels by pistons. The Pistons can be rigid or rotatable on an axis Roll piston be formed, being in the cylinder channels run smoothly. A rotor disc is in one Sunken cover so that both together to Form a flat surface on the cylinder side of the rotor. Here the rotor disc is eccentric to the side of the rotor attached and engages with the pistons in the cylinder channels.

Der besondere Vorteil einer Rotationskolbenpumpe nach der Erfindung wird darin gesehen, daß eine Wartung durch Schmierung nicht erforderlich ist. The particular advantage of a rotary piston pump according to the Invention is seen in that maintenance by Lubrication is not required.  

Im folgenden werden Ausführungsbeispiele der Erfindung beschrieben unter Bezugnahme auf die beiliegenden Zeichnungen.The following are exemplary embodiments of the invention described with reference to the accompanying Drawings.

Fig. 1 zeigt einen Schnitt längs einer Achse bei einer Rotationskolbenpumpe mit zwei Zylinderkanälen Fig. 1 shows a section along an axis in a rotary piston pump with two cylinder channels

Fig. 2 stellt bei der Ausführungsform nach Fig. 1 einen Schnitt quer zur Achse dar Fig. 2 shows a section transverse to the axis in the embodiment of FIG. 1

Fig. 3 zeigt einen Schnitt durch eine Ausführungsform der Erfindung mit drei Zylinderkanälen. Fig. 3 shows a section through an embodiment of the invention with three cylinder channels.

Bei sämtlichen Ausführungsformen ist in einem Gehäuse 6 ein Rotor 7 mit Zylinderkanälen 8 in radialer Richtung angeordnet. Anzahl und Lage der Zylinderkanäle 8 im Rotor 7 ist beliebig. Bei der Ausführungsform nach Fig. 1 und 2 sind zwei Zylinderkanäle vorgesehen, bei der Ausführungsform nach Fig. 3 drei Zylinderkanäle. Grundsätzlich kann die Anzahl der Zylinderkanäle beliebig sein.In all embodiments, a rotor 7 with cylinder channels 8 is arranged in a radial direction in a housing 6 . The number and position of the cylinder channels 8 in the rotor 7 is arbitrary. In the embodiment according to FIGS. 1 and 2, two cylinder channels are provided, in the embodiment according to FIG. 3 three cylinder channels. In principle, the number of cylinder channels can be arbitrary.

Entsprechend der Zylinderkanäle 8 im Rotor 7 müssen Kolben 10 auf einer Rotorscheibe 9 angebracht sein. Bei zwei Zylinderkanälen 8 beträgt, um ausgeglichen zu sein, die versetzte Anordnung 90°. Den einzelnen Zylinderkanälen 8 ist jeweils ein Kolben 10 zugeordnet.Corresponding to the cylinder channels 8 in the rotor 7 , pistons 10 must be mounted on a rotor disk 9 . In the case of two cylinder channels 8 , the offset arrangement is 90 ° to be balanced. A piston 10 is assigned to the individual cylinder channels 8 .

Bei der Drehung des Rotors 7 überlaufen die Zylinderöffnungen 11 Ein- und Auslaßkanäle 12, wobei sich die Kolben 10 über den Mittelpunkt der Zylinderkanäle 8 von einer Seite zur anderen bewegen. Vorteilhaft sind die Kolben als Rollkolben 10 ausgebildet. Sie sind dabei jeweils auf einer Rotorscheibe 9 auf einer Achse 10a drehbar angebracht und in einem Gehäusedeckel 6a exzentrisch zum Rotor 7 gelagert.When the rotor 7 rotates, the cylinder openings 11 overflow the inlet and outlet channels 12 , the pistons 10 moving from one side to the other over the center of the cylinder channels 8 . The pistons are advantageously designed as roller pistons 10 . They are each rotatably mounted on a rotor disk 9 on an axis 10 a and mounted eccentrically to the rotor 7 in a housing cover 6 a.

Die Kolben können aber auch starr auf ihren Achsen angeordnet sein. Die Zylinderkanäle 8 im Rotor 7 sind auf einer Seite offen und werden durch den Gehäusedeckel 6a und die Rotorscheibe 9 verschlossen. Der Rotor 7 und die Rotorscheibe 9 sind durch die Kolben 10 unmittelbar miteinander verbunden und haben bei der Umdrehung ein Drehverhältnis 1 : 2.The pistons can also be arranged rigidly on their axes. The cylinder channels 8 in the rotor 7 are open on one side and are closed by the housing cover 6 a and the rotor disk 9 . The rotor 7 and the rotor disk 9 are directly connected to one another by the pistons 10 and have a rotation ratio of 1: 2 during the rotation.

Um einen ölfreien Förderstrom der Pumpe zu gewährleisten, ist es von Vorteil, die als Rollkolben ausgebildeten Kolben mit geschlossenen dauergeschmierten Kugellagern zu versehen.To ensure an oil-free flow of the pump, it is advantageous to use the pistons designed as roller pistons closed permanently lubricated ball bearings.

Um exakte Steuerzeiten zu erreichen, müssen die Zylinderöffnungen 11 zu den Ein- und Auslaßkanälen 12 im Gehäuse 6 zueinander abgestimmt sein.In order to achieve exact control times, the cylinder openings 11 to the inlet and outlet channels 12 in the housing 6 must be coordinated with one another.

Eine Pumpe nach der Erfindung läuft vollständig ausgeglichen und läßt hohe Drehzahlen zu. Hierbei wird durch die Zentrifugalkraft das Medium nach außen geschleudert und zusätzlich von den Kolben 10 aus den Zylinderkanälen 8 herausgedrückt. Die Rollkolben laufen hierbei in den Zylinderkanälen reibungslos ab. Die Rotorscheibe 9 ist in dem Gehäusedeckel 6a so eingelassen, daß beide zusammen zur Zylinderseite des Rotors 7 eine ebene Fläche bilden. Hierbei ist die Rotorscheibe 9 exzentrisch seitlich zum Rotor 7 angebracht und greift mit den Kolben in die Zylinderkanäle 8.A pump according to the invention runs completely balanced and allows high speeds. The medium is thrown outwards by the centrifugal force and additionally pushed out of the cylinder channels 8 by the pistons 10 . The rolling pistons run smoothly in the cylinder channels. The rotor disk 9 is embedded in the housing cover 6 a so that both together form a flat surface on the cylinder side of the rotor 7 . Here, the rotor disk 9 is mounted eccentrically to the side of the rotor 7 and engages with the pistons in the cylinder channels 8 .
