Abstract
Description
Die Erfindung betrifft eine Pumpe, insbesondere eine Flügelzellenpumpe, welche zwei so genannte Fluten aufweist, wobei die zwei Fluten durch ein Rückschlagventil getrennt oder verbunden sein können.The The invention relates to a pump, in particular a vane pump, which has two so-called floods, the two floods by a check valve be disconnected or connected.
Derartige Pumpen sind bekannt. Sie werden z. B. als Ölpumpe für die Schmierölversorgung eines Verbrennungsmotors eingesetzt. Die Pumpe besitzt dabei zwei voneinander getrennte Druckkanäle, die je mit einer Druckniere (Flut) der Flügelzellenpumpe verbunden sind. Ein temperaturgeregeltes Ventil öffnet bei niedrigen Öltemperaturen eine Verbindung von einer Druckniere zu einem Saugkanal, so dass das Öl der zweiten Flut drucklos umgefördert wird. Bei hohen Temperaturen schließt das Ventil, und das Öl der zweiten Flut wird über ein Rückschlagventil ebenfalls in das Schmierölsystem gefördert. Beim Einsatz bekannter Rückschlagventile, welche aus einem Schließkörper, z. B. einer Kugel, und einer Schraubenfeder bestehen, sind mehrere Bauteile notwendig, was die Kosten für diese Bauteile und deren Montage erhöht. Weiterhin ist der Bauraum für federunterstützte Rückschlagventile relativ groß, da die Kugel, die Feder und ein evtl. Verschlussstopfen hintereinander angeordnet sind.such Pumps are known. They are z. B. as an oil pump for the lubricating oil supply used an internal combustion engine. The pump has two separate pressure channels, which are each connected to a pressure kidney (flood) of the vane pump. A temperature controlled valve opens at low oil temperatures a connection from one pressure kidney to a suction channel, so that the oil of the second Flooded unpressurized becomes. At high temperatures, the valve closes, and the oil of the second Tide is over a check valve as well in the lubricating oil system promoted. When using known non-return valves, which consists of a closing body, for. As a ball, and a coil spring are several Components necessary, what the cost of these components and their Mounting increased. Furthermore, the space for spring-assisted check valves relatively large, because the ball, the spring and a possible sealing plug in a row are arranged.
Es ist also Aufgabe der Erfindung, eine Pumpe darzustellen, die diese Nachteile nicht aufweist.It So is the object of the invention to present a pump, this Disadvantages not.
Die Aufgabe wird gelöst durch eine Pumpe, insbesondere Flügelzellenpumpe, welche zwei Fluten aufweist, wobei die zwei Fluten durch ein Rückschlagventil getrennt oder verbunden sein können, wobei das Rückschlagventil einen einstückigen Ventilkörper aufweist und der Ventilkörper drei unterschiedlich gestaltete Funktionsbereiche aufweist. Erfindungsgemäß stellen die Funktionsbereiche einen Dichtkörper, einen elastischen Steg und ein Einspannelement dar. Das hat den Vorteil, dass entsprechend ihrer Funktion die Funktionsbereiche unabhängig voneinander dimensioniert werden können und doch nur ein Montageteil darstellen.The Task is solved by a pump, in particular vane pump, which two Flooding, the two floods through a check valve be disconnected or connected, where the check valve a one-piece valve body and the valve body has three differently designed functional areas. According to the invention the functional areas a sealing body, an elastic web and a clamping element. This has the advantage that accordingly their function, the functional areas independently dimensioned can and can but only an assembly part represent.
Bevorzugt wird eine Pumpe, bei welcher der Ventilkörper teilweise in einem Pumpengehäuse und teilweise in einer Zwischenplatte angeordnet ist. Auch wird eine Pumpe bevorzugt, bei welcher das Pumpengehäuse und die Zwischenplatte für den Dichtkörper gemeinsam einen Ventildichtsitz bilden. Das hat den Vorteil, dass der Ventilkörper vor Montage der Zwischenplatte auf das Gehäuse einfach durch Einlegen zwischen beide Teile montiert werden kann.Prefers is a pump in which the valve body partially in a pump housing and partially is arranged in an intermediate plate. Also, a pump is preferred in which the pump housing and the intermediate plate for the sealing body together form a valve seat. This has the advantage that the valve body before mounting the intermediate plate on the housing simply by inserting can be mounted between both parts.
Eine erfindungsgemäße Pumpe zeichnet sich dadurch aus, dass das Einspannelement im Wesentlichen als ein mehrfach abgeflachter Zylinderkörper bzw. ein Mehrkantkörper ausgeführt ist, vorzugsweise mit Fasen versehen, welcher in einer zylindrischen Ausnehmung des Pumpengehäuses und/oder der Zwischenplatte eingespannt angeordnet ist und nach Montage durch die Zwischenplatte gehalten wird. Der mehrfach abgeflachte Zylinderkörper oder Mehrkantkörper hat den Vorteil, dass in der zylindrischen Ausnehmung durch die abgeflachten Bereiche Platz zum Verformen des Einspannelementes geschaffen wird.A inventive pump is characterized in that the clamping element substantially is designed as a multi-flattened cylinder body or a polygonal body, preferably provided with chamfers, which in a cylindrical Recess of the pump housing and / or the intermediate plate is arranged clamped and after Assembly is held by the intermediate plate. The flattened several times cylinder body or polygonal body has the advantage that in the cylindrical recess through the flattened areas Place to deform the clamping element is created.
Weiterhin wird eine Pumpe bevorzugt, bei welcher der Dichtkörper als kreisförmige, runde Scheibe ausgebildet ist und im Dichtsitzbereich ggf. eine Fase oder einen Kegelstumpfbereich aufweist, ggf. mit Dichtlippen gegen Unebenheiten des Gehäuses oder der Zwischenplatte. Das hat den Vorteil, dass auch bei fertig gegossener Pumpengehäuse- oder Zwischenplattenoberfläche ohne Nachbearbeitung eine ausreichende Dichtwirkung des Dichtkörpers gegenüber dem Dichtsitz gewährleistet ist.Farther a pump is preferred in which the sealing body as circular, round disc is formed and possibly in the sealing seat area a Has chamfer or a truncated cone area, possibly with sealing lips against bumps of the housing or the intermediate plate. This has the advantage that even when finished cast pump housing or Between plate surface without reworking a sufficient sealing effect of the sealing body against the Sealing seat guaranteed is.
Eine erfindungsgemäße Pumpe zeichnet sich dadurch aus, dass der Dichtkörper und das Einspannelement durch den elastischen Steg miteinander verbunden sind, welcher beispielsweise in einer Ausnehmung im Gehäuse zwischen der zylindrischen Ausnehmung für das Einspannelement und einem Ökanal angeordnet ist. Bevorzugt wird auch eine Pumpe, bei welcher der elastische Steg die Funktion einer Biegefeder oder eines biegeelastischen Scharniers aufweist. Das hat den Vorteil, dass durch entsprechende konstruktive Dimensionierung des Steges die Federkraft gezielt einstellbar ist.A inventive pump is characterized in that the sealing body and the clamping element are interconnected by the elastic web, which for example in a recess in the housing disposed between the cylindrical recess for the clamping element and a Ökanal is. Also preferred is a pump in which the elastic Bridge the function of a spiral spring or a bending elastic hinge having. This has the advantage that by appropriate constructive Dimensioning of the web, the spring force is specifically adjustable.
Bevorzugt wird weiterhin eine Pumpe, bei welcher die Mittelachsen von Dichtkörper und Einspannelement um 90° gegeneinander versetzt sind. Weiterhin wird eine Pumpe bevorzugt, bei welcher der Ventilkörper aus einem elastischen Werkstoff, insbesondere einem Gummiwerkstoff, hergestellt ist.Prefers is still a pump, in which the center axes of the sealing body and Clamping element 90 ° to each other are offset. Furthermore, a pump is preferred in which the valve body from an elastic material, in particular a rubber material, is made.
