STAND DER TECHNIKSTATE OF TECHNOLOGY
Aus der
DARSTELLUNG DER ERFINDUNGPRESENTATION THE INVENTION
Ausgehend von diesem vorbekannten Stand der Technik liegt der Erfindung die Aufgabe zugrunde, eine verbesserte Pumpe der eingangs genannten Art anzugeben.Based on this previously known State of the art, the invention has for its object a to provide improved pump of the type mentioned.
Diese Erfindung ist durch die Merkmale des Hauptanspruchs gegeben. Sinnvolle Weiterbildungen der Erfindung sind Gegenstand von sich an den Hauptanspruch anschließenden weiteren Ansprüchen.This invention is through the features of the main claim. Useful developments of the invention are the subject of others following on from the main claim Claims.
Die erfindungsgemäße Pumpe zeichnet sich dadurch aus, dass die Schieberführung nicht direkt sondern mittelbar über entsprechende Dichtkörper an den sie umgebenden drehfesten Pumpenteilen abdichtend anliegt. Diese Dichtkörper sind zumindest bereichsweise vorhanden. So können sie beispielsweise nicht in dem Bereich der Schieberführung vorhanden sein, der den nutartigen Durchbruch für den durch den Durchbruch hindurchragenden, sich in axialer Richtung hin und her bewegenden Rotorkragen erforderlich ist. Erfindungsgemäß ist vorgesehen, dass ein solcher Dichtkörper zwischen der Schieberführung und zumindest dem Deckel, der Mantelwand und der Rückwand des Gehäuses vorhanden ist. In den in radialer Richtung an die Schieberführung angrenzenden inneren drehfesten Pumpenteilen kann ebenfalls ein Dichtkörper bereichsweise vorhanden sein.The pump according to the invention is characterized by this from that the slide guide not directly but indirectly via appropriate sealing body the surrounding non-rotatable pump parts sealingly rests. This sealing body are available at least in some areas. For example, they cannot in the area of the slide guide be present, the groove-like breakthrough for the through the breakthrough protruding, moving back and forth in the axial direction Rotor collar is required. According to the invention it is provided that a such sealing body between the slide guide and at least the lid, the jacket wall and the rear wall of the housing is available. In the radial direction adjacent to the slide guide inner rotationally fixed pump parts can also have a sealing body in some areas to be available.
Ein solcher Dichtkörper kann durch einen schnurartigen Dichtkörper verwirklicht werden, der teilweise versenkt in einer entsprechend in der Schieberführung umlaufenden Nut einsitzt.Such a sealing body can through a cord-like sealing body be realized, which is partially sunk in a corresponding manner in the slide guide circumferential groove sits.
Zur Lagefixierung der Schieberführung in dem Pumpengehäuse ist nach einem auch in der Zeichnung dargestellten Ausführungsbeispiel vorgesehen, dass zumindest eine der Schrauben, mit denen der Deckel an der Rückwand befestigt ist, mit ihrem Schraubenschaft längs durch die Schieberführung hindurchragt.To fix the slide guide in the pump housing is according to an embodiment shown in the drawing provided that at least one of the screws holding the lid on the back wall is attached, with its screw shaft protrudes lengthwise through the slide guide.
Zusätzlich kann zumindest ein Kragstift von jeder der in axialer Richtung einander gegenüberliegenden Stirnseiten der Schieberführung auskragen, der jeweils in eine entsprechende Vertiefung des Deckels beziehungsweise der Rückwand eingreift. Auf diese Weise kann eine kippsichere und in axialer Richtung lagefixierte Positionierung der Schieberführung in dem Pumpengehäuse ermöglicht werden.In addition, at least one cantilever pin of each of the axially opposite end faces of the slide guide cantilever, each in a corresponding recess in the lid or the back wall intervenes. In this way it can be tilt-proof and in the axial direction positionally fixed positioning of the slide guide in the pump housing are made possible.
Um die Gleitfähigkeit des an der Schieberführung in axialer Richtung längs verschieblichen Schiebers zu erhöhen, kann als jeweilige Gleitfläche des Schiebers an der Schieberführung nicht die vollflächige Oberfläche der Schieberführung vorgesehen werden, sondern es können lediglich leistenartige Oberflächenbereiche an der entsprechenden Oberfläche der Schieberführung ausgebildet werden, die als Gleitflächen für den Schieber dienen sollen.To ensure the sliding ability of the on the slide guide in axial direction along sliding slider to increase can be used as the respective sliding surface of the Slide on the slide guide not the full area surface the slide guide can be provided, but it can only strip-like surface areas on the appropriate surface the slide guide are trained to serve as sliding surfaces for the slide.
Der Dichtkörper kann elastisch verformbar und dabei auch pneumatisch oder hydraulisch ausdehnbar sein.The sealing body can be elastically deformed and can also be expanded pneumatically or hydraulically.
Zur kippsicheren Halterung des Schiebers an der Schieberführung kann, wie auch das in der Zeichnung dargestellte Ausführungsbeispiel zeigt, eine parallel zur Verstellrichtung des Schiebers verlaufende Längsnut in ihm vorhanden sein. Von dem Gehäuse können quer in diese Längsnut eingreifende Kragglieder vorhanden sein. Ein solches Kragglied kann beispielsweise an der Mantelwand des Pumpengehäuses befestigt sein. Der Schieber selber braucht daher keinen direkten Kontakt mit der Mantelwand zu haben.For tilt-proof mounting of the slide the slide guide can, like the embodiment shown in the drawing shows a parallel to the direction of adjustment of the slide longitudinal groove to be present in it. From the housing can engage transversely in this longitudinal groove Cantilever links are present. Such a cantilever can, for example on the jacket wall of the pump housing be attached. The slide itself therefore does not need a direct one To have contact with the jacket wall.
Auch im radial inneren Bereich des Schiebers können ihn quer zur axialen Richtung abstützende Widerlager vorhanden sein. Solche Widerlager, die ebenfalls durch beispielsweise zwei Haltestifte verwirklicht werden können, können von den beiden in axialer Richtung an die Nabe des Rotors anschließenden drehfesten Büchsen auskragend vorhanden sein.Even in the radially inner area of the Can slide abutment supporting it transverse to the axial direction his. Such abutments, for example, by two Retaining pins can be realized by the two in axial Cantilevered sleeves projecting towards the hub of the rotor to be available.
Der Querschnitt der in der Zeichnung beispielhaft dargestellten Schieberführung ist der Form eines Trapezes angenähert. Auf diese Weise kann mittels eines Schiebers, der zumindest in seinem in axialer Richtung mittleren Bereich einen der Form eines Parallelogrammes angenäherten Querschnitt besitzt, ein wirkungsvolles Zusammenwirken zwischen dem Schieber und seiner Schieberführung hergestellt werden. Der Schieber kann dabei an seinen in axialer Richtung vorderen und hinteren Stirnseiten ebenflächig oder gebogen abgeschrägt sein, wodurch seine Gleitfähigkeit noch erhöht wird.The cross section of the slide guide shown as an example in the drawing approximates the shape of a trapezoid. That way an effective interaction between the slide and its slide guide is produced by means of a slide, which has a cross-section approximating the shape of a parallelogram, at least in its central region in the axial direction. The slider can be beveled flat or curved on its front and rear end faces in the axial direction, which further increases its sliding ability.
Weitere Vorteile und Merkmale der Erfindung sind den in den Ansprüchen ferner angegebenen Merkmalen sowie den nachstehenden Ausführungsbeipielen zu entnehmen.Other advantages and features of Invention are those in the claims further specified features and the following exemplary embodiments refer to.
