Description

Die Erfindung betrifft eine Verdrängerpumpe mit den Merkmalen des Oberbegriffs von Anspruch 1.The invention relates to a positive displacement pump with the Features of the preamble of claim 1.

Aus DE 41 07 720 A1 bereits eine Verdrängerpumpe bekannt, deren die beiden Kammern des Pumpengehäuseraumes voneinander trennender, zwangsgeführter Flügel an beiden Stirnenden jeweils eine in Flügellängsrichtung beweglich geführte und an der Innenumfangswand des Gehäuseraumes anliegende Abdichtleiste trägt.A positive displacement pump is already known from DE 41 07 720 A1, whose the two chambers of the pump housing space separating, guided wing on both Front ends each movable in the longitudinal direction of the wing guided and on the inner peripheral wall of the housing space wearing sealing strip.

Zur beweglichen Anordnung der Abdichtleisten sind diese im Querschnitt T-förmig ausgebildet, wobei der T-Balken außenseitig im Querschnitt konvex gekrümmt ist und demgemäß die Umfangswand lediglich entlang einer Mantellinie berührt.For the movable arrangement of the sealing strips, these are in Cross-section T-shaped, the T-beam is convexly curved on the outside in cross section and accordingly the peripheral wall only along a surface line touched.

Der mittlere Leistensteg ist mit einer in den Flügel stirnseitig eingeformten Längsnut in Flügellängsrichtung beweglich in Eingriff gebracht, so dass sich die Abdichtleisten bei der Rotation der Antriebswelle unter Fliehkraftwirkung selbsttätig an die Gehäuseinnenumfangswand anlegen.The middle ledge is on the front with one in the wing molded longitudinal groove movable in the longitudinal direction of the wing engaged so that the sealing strips when the drive shaft rotates under the action of centrifugal force automatically attach to the inner wall of the housing.

Der Nachteil dieser Konstruktion besteht darin, dass die Abdichtleisten erst ab einer bestimmten Drehzahl der Antriebswelle unter Zentrifugalkrafteinwirkung zur abdichtenden Anlage an die Innenumfangswand des Gehäuseraumes gelangen und erst ab diesem Zeitpunkt eine Kammerabdichtung zustande kommt, die eine zuverlässige Förderung eines gasförmigen oder flüssigen Strömungsmittels gewährleistet.The disadvantage of this construction is that the Sealing strips only from a certain speed Drive shaft under centrifugal force to be sealed System on the inner peripheral wall of the housing space arrive and only from this point in time a chamber seal comes about, which is a reliable promotion of a gaseous or liquid fluid guaranteed.

Verdrängerpumpen dieser Ausführungsform eignen sich deshalb z.B. nicht für die Evakuierung eines Bremskraftverstärkers eines KfZ, da in diesem Falle bereits bei kleinen Drehzahlen eine Evakuierung sichergestellt sein muss.Positive displacement pumps of this embodiment are therefore suitable e.g. not for the evacuation of a brake booster a motor vehicle, since in this case even small ones Speeds an evacuation must be ensured.

Die heutzutage hergestellten Verdrängerpumpen sind in der Regel schwer und werden daher nur vereinzelt bei Kraftfahrzeugen eingesetzt.The positive displacement pumps manufactured today are in the Usually difficult and are therefore only occasionally at Motor vehicles used.

Der Erfindung liegt daher die Aufgabe zugrunde, eine Verdrängerpumpe bereitzustellen, die problemlos auch bei Kraftfahrzeugen eingesetzt werden kann. The invention is therefore based on the object Provide positive displacement pump, which also without problems Motor vehicles can be used.

Diese Aufgabe wird erfindungsgemäß mit einer Verdrängerpumpe gelöst, die die Merkmale des Anspruches 1 aufweist.This object is achieved with a Displacement pump solved the features of claim 1 having.

Durch die Verwendung von Metall, Kunststoff, Keramik und/oder einer Verbindung hiervon für dass den Pumpenrotor und/oder den Rotorflügel können für den jeweiligen Einsatzzweck die optimalen Materialpaarungen herausgesucht werden. Die Bauteile, die stark beansprucht werden, werden aus einem härteren Material, z.B. Metall Und/oder Keramik hergestellt, wobei die Bauteile, die kinematisch stark beansprucht werden, d.h. die oft beschleunigt und verzögert werden, bestehen aus einem leichteren Material.Through the use of metal, plastic, ceramic and / or a connection thereof for the pump rotor and / or the rotor blade can for the respective Purpose selected the optimal material pairings become. The components that are heavily used are made of a harder material, e.g. Metal and / or ceramic manufactured, the components being kinematically strong be claimed, i.e. which often accelerates and decelerates are made of a lighter material.

Erfindungsgemäß ist die Verbindung eine Metall-Kunststoff-Verbindung, Metall-Keramik-Verbindung, Metall-Kunststoff-Keramik-Verbindung oder Kunststoff-Keramik-Verbindung.According to the invention, the connection is a metal-plastic connection, Metal-ceramic connection, metal-plastic-ceramic connection or plastic-ceramic connection.

Alternativ hierzu kann z. B. in jede der Vertiefungen 42, 44 eine Druckfeder 50 bzw. 52 eingebracht sein, auf denen sich die Leistenführungsstücke 36, 38 abstützen (Fig. 3).Alternatively, e.g. B. in each of the recesses 42, 44 a compression spring 50 or 52 can be introduced, on which the ledge guide pieces 36, 38 are supported (FIG. 3).

Der Rotorflügel 18 sowie die Abdichtleisten 20, 22 sind vorzugsweise als Kunststoffspritzteil ausgeführt, wobei der Rotorflügel 18 insbesondere zwecks gleichmäßiger Materialverteilung beim Spritzprozess bspw. mit drei diesen in Querrichtung parallel zu dessen Flachseiten durchsetzenden, flachschlitzartigen Ausnehmungen 54 ausgestattet ist. Der Pumpenrotor 16 kann im Gehäuseraum 12 auch zentral gelagert sein, sofern letzterer eine ovale Umfangsform aufweist.The rotor blades 18 and the sealing strips 20, 22 are preferably designed as a molded plastic part, the Rotor blades 18 in particular for the purpose of uniform material distribution in the spraying process, for example with three of these in Transverse direction parallel to its flat sides, Flat slot-like recesses 54 is equipped. The Pump rotor 16 can also be stored centrally in the housing space 12 if the latter has an oval peripheral shape.

Die Verdrängerpumpe gemäß den Figuren 5 und 6 umfasst einen Flanschkörper mit einem ein Pumpengehäuse 61 bildenden Zylindertopf 62, eine in diesem gelagerte Pumpenantriebswelle 63 mit aufgesetztem Rotor 64 und einen in einer über die Rotormitte verlaufenden Aussparung geführten, als Ganzes mit 65 bezeichneten, zweigeteilten Flügel. Dieser ist, wie Figur 7 zeigt, vorzugsweise durch symmetrische, flache Flügelteilstücke 65', 65'' gebildet, die an ihrem äußeren Ende jeweils ein Drehlager aufweisen, auf dem eine Abdichtleiste 66 um eine zur Rotordrehachse parallele Achse schwenkbar gelagert ist.The positive displacement pump according to FIGS. 5 and 6 comprises one Flange body with a pump housing 61 forming Cylinder cup 62, a pump drive shaft mounted in this 63 with attached rotor 64 and one in one the recess running rotor center, as Whole with 65 marked, two-part wings. This 7, preferably by symmetrical, flat wing sections 65 ', 65' 'formed on their outer end each have a pivot bearing on which one Sealing strip 66 about an axis parallel to the axis of rotation of the rotor is pivotally mounted.

Das andere Ende der Flügelteilstücke 65', 65" ist so ausgebildet, dass diese entweder stumpf (siehe Fig. 7) oder als Nut und Feder (siehe Fig. 5) miteinander in Eingriff sind.The other end of the wing sections 65 ', 65 "is like this trained that this either blunt (see Fig. 7) or as tongue and groove (see Fig. 5) in engagement with each other are.

Im letzteren Falle ist innerhalb des Flügelteilstückes 65'', was nicht gezeigt ist, eine geeignete Druckfeder zu positionieren, während im anderen Falle, wie aus Figur 7 zu ersehen ist, zwischen beiden Flügelendstücken 65', 65'' eine Z-förmige Formfeder 67 angeordnet ist, durch die beide Flügelteilstücke 65', 65" auseinander bewegt und dadurch die Abdichtleisten 66 mit einer definierten Anpresskraft an den Innenumfang des Zylindertopfes 62 angelegt werden.In the latter case it is inside the wing section 65 '', which is not shown, a suitable compression spring position while in the other case, as shown in Figure 7 between the two wing end pieces 65 ', 65' ' a Z-shaped form spring 67 is arranged through which both Wing sections 65 ', 65 "moved apart and thereby the sealing strips 66 with a defined contact pressure the inner circumference of the cylinder pot 62 are created.

Die Abdichtleisten 66 sind zur Wand des Zylindertopfes 62 hin mit einem konkaven Radius 68 versehen (Fig. 5). Somit ergeben sich zwei Berührungslinien bei 69 und 70, die im Zusammenwirken mit den flachen Flügelteilstücken 65', 65'' zur Abdichtung der Kammern vor und hinter dem Flügel 65 dienen. An den Enden der Abdichtleisten 66 sind Radien 71 und 72 vorgesehen, wodurch eine optimale Nachabdichtung erreicht wird.The sealing strips 66 face the wall of the cylinder pot 62 provided with a concave radius 68 (Fig. 5). Consequently there are two lines of contact at 69 and 70, which in Interaction with the flat wing sections 65 ', 65' ' to seal the chambers in front of and behind the wing 65 serve. Radii 71 are at the ends of the sealing strips 66 and 72 are provided, which ensures optimal resealing is achieved.

Der Rotor 64 ist zur Antriebswelle 63 hin als Führung für den Flügel 65 geschlitzt und auf die Welle 63 aufgesteckt, eingesteckt oder angespritzt.The rotor 64 is towards the drive shaft 63 as a guide for slotted the wing 65 and plugged onto the shaft 63, inserted or molded.

Bei der Rotation der Antriebswelle 63 können sich die beiden Flügelteilstücke 65', 65" voneinander unabhängig im Rotor 64 radial bewegen. Die Abdichtleisten 66 legen sich in jedem Drehwinkel mit beiden Enden (bei 69 und 70) an den Innenumfang des Zylindertopfes 62 an und verändern dadurch ihren Anstellwinkel zur translatorischen Achse des Flügels 65. Durch die Fixierung der Abdichtleisten 66 in den Drehlagern der Flügelteilstücke 65', 65" und der Veränderung des Anstellwinkels bei einer Rotation der Antriebswelle 63 wird der Achsabstand der beiden Drehlager zueinander, bei Anliegen der Abdichtleisten 66 an der Innenumfangsfläche des Zylindertopfes 62, zusätzlich zur variablen, geometrischen Größe des theoretischen Achsmaßes in der Flügelachse, veränderlich.When the drive shaft 63 rotates, the two wing sections 65 ', 65 "independently of each other in Move rotor 64 radially. The sealing strips 66 lie down at each angle of rotation with both ends (at 69 and 70) on the Inner circumference of the cylinder pot 62 and thereby change their angle of attack to the translational axis of the wing 65. By fixing the sealing strips 66 in the Pivots of the wing sections 65 ', 65 "and Changing the angle of attack when rotating the Drive shaft 63 becomes the center distance of the two rotary bearings to each other, when the sealing strips 66 are in contact with the Inner peripheral surface of the cylinder pot 62, in addition to variable, geometric size of the theoretical axis dimension in the wing axis, changeable.

Diese Längenänderung wird durch die Radialbeweglichkeit der Flügelteilstücke 65', 65'' ausgeglichen. Die Anpassung an die variable Länge im Drehwinkel geschieht durch das Anpressen der Abdichtleisten 66 und der Mitnahme des Flügels 65 durch die Antriebswelle 63 durch die Formfeder 67 bzw. durch eine entsprechende Druckfeder, welche die Flügelteilstücke 65', 65'' auseinanderdrückt und die mit diesen verbundenen Abdichtleisten 66 an die Zylindertopfwand anpresst.This change in length is due to the radial mobility of the Wing sections 65 ', 65' 'balanced. The adaptation to the variable length in the angle of rotation happens through that Pressing the sealing strips 66 and taking the Wing 65 through the drive shaft 63 through the shaped spring 67 or by a corresponding compression spring, which the Wing sections 65 ', 65' 'apart and with this connected sealing strips 66 to the Pressed on cylinder wall.
