Definitions
- Known vane pumps of the generic type have a rotor in which Wings are slidably guided in radial slots. The outer Ends of the wings slide in a cam ring which encompasses the delivery space.
- This The cam ring can be pivoted on one side in a housing in a fixed bearing stored. In the stationary state of the rotor, it is turned into a spring force Position of maximum funding pushed and held. Furthermore stands with the Hubring an actuator in engagement, the actuating force against the maximum Promotion directed spring force acts.
- the cam ring is also on a Housing pivoted axle.
- vane pumps with vanes arranged in the rotor, guided in radial slots, and a cam ring which is slidably mounted in the stationary housing.
- a guide ring rotatably guided in the cam ring surrounds and rotates with the wings.
- the conveying spaces are filled and pushed out of them via radial openings in the guide ring or to radially surrounding spaces in the lifting ring.
- These spaces in the cam ring have openings in the plane of the guide surfaces, which lie against openings of channels in the stationary housing. This ensures a favorable radial inflow and outflow to and from the delivery rooms.
- the invention is based, for a volume-adjustable vane pump the task to create a positive and non-positive bearing for the cam ring, which can be designed to be mechanically compact and low-friction.
- FIG. 1 shows a section of a vane pump 1 designed according to the invention, which has the following basic structure:
- vanes 5 are arranged so that they can be pushed.
- the outer ends of the vanes 5 slide in the inner contour 6 of a cam ring 7 surrounding the rotor 4, which forms the delivery chamber 8 with the circumferential, volume-variable delivery chambers 9.
- a pressure element 19 engages in the housing 10, which him towards - zero conveyance - against one in the housing 10
- Actuating device 11 urges and holds it in engagement
- the pressure element 19 can act by spring force or by applying pressure oil.

Abstract
Description
- Fig.1
- eine erfindungsgemäße Flügelzellenpumpe
- Fig. 2
- die Lagerung des Hubringes im Gehäuse in vergrößerter Darstellung.
In radialen Schlitzen 3 eines in einem Gehäuse 10 gelagerten Rotors 4 sind Flügel 5 schubbeweglich geführt angeordnet. Die äußeren Enden der Flügel 5 gleiten in der Innenkontur 6 eines den Rotor 4 umgebenden Hubringes 7, der den Förderraum 8 mit den umlaufenden, volumenveränderlichen Förderkammern 9 bildet.
Claims (6)
- Mengenregelbare Flügelzellenpumpe mit folgender Bauart:in einem Rotor sind in radialen Schlitzen Flügel schubbeweglich geführt angeordnet,die äußeren Enden der Flügel gleiten in einen, einen Förderraum umfassenden Hubring,der Hubring ist in einem Gehäuse einseitig in einer ortsfesten Lagerstelle des Gehäuses schwenkbar gelagert, wobei ihn eine Federkraft im stehenden Zustand des Rotors in eine Stellung maximaler Förderung drängt und hält,mit dem Hubring steht ein Stellglied im Eingriff, dessen Stellkraft entgegen der auf maximale Förderung gerichteten Federkraft (F) wirkt,
gekennzeichnet durch folgende Merkmale:im Gehäuse (10) ist innen eine offene Lagermulde (18) angeordnet, in welcher ein am Hubring (7) radial angeformtes, komplementäres Lagersegment (73) schwenkbar gelagert ist,am Stellring (7) wirkt stetig eine resultierende Kraft, welche durch die beim Umlauf des Rotors (4) und beim Fördern wirkende Kräfte und solche eines oder mehrerer Druckelemente (19) bestimmt ist und eine solche Wirkrichtung aufweist, daß das Lagersegment (73) in der Lagermulde (18) des Gehäuses (10) kraftschlüssig gehalten ist. - Mengenregelbare Flügelzellenpumpe nach Anspruch 1;

dadurch gekennzeichnet,
daß der Rotor (4) eine solche Drehrichtung aufweist, bei der die resultierende Kraft des Reibmomentes zwischen Rotor (4) und Hubring (7) in Richtung der Stelleinrichtung (11) gerichtet ist. - Mengenregelbare Flügelzellenpumpe nach Anspruch 1;
dadurch gekennzeichnet
daß der Hubring (7) radialgerichtete, mittig im Lagersegment (73) mündende Überströmkanäle (72) aufweist, denen in der Mitte der Lagermulde (18) Öffnungen (101) im Gehäuse (10) gegenüber angeordnet sind. - Mengenregelbare Flügelzellenpumpe nach Anspruch 1,
dadurch gekennzeichnet,
daß die mittig im Lagersegment (73) mündenden Überströmquerschnitte (71) von den druckseitigen Förderkammern (9) beaufschlagt sind und die Überströmkanäle (72) in der im Gehäuse (10) geformten Lagermulde (18) den Zulauf zum Druckkreis (D) über die Öffnungen (101) bilden. - Mengenregelbare Flügelzellenpumpe nach Anspruch 1,
dadurch gekennzeichnet,
daß der Außendurchmesser (RA) Lagersegment (73) geringfügig größer ist als der Innendurchmesser (Rl) der Lagermulde (18) im Gehäuse (10).
