Eine
weitere regelbare Pumpe ist aus der
Der Erfindung liegt die Aufgabe zu Grunde, die Lebensdauer einer regelbaren Pumpe zu erhöhen.Of the Invention is the object of the life of a controllable Increase the pump.
Die Lösung dieser Aufgabe erfolgt erfindungsgemäß mit dem Merkmal des Anspruchs 1.The Solution of this problem is inventively with the feature of claim 1.
Gemäß der Erfindung ist bei einer regelbaren Pumpe mit einem an einem Pumpengehäuse gelagerten Rotor sowie einem den Rotor umgebenden Stellelement, welches in dem Pumpengehäuse nach Art eines Verstellkolbens verschiebbar gelagert ist, eine Gleit- und Dichtführung vorgesehen, die an dem Pumpengehäuse eine erste Gleitfläche und an dem Stellelement eine auf die erste Gleitfläche bezogene zweite Gleitfläche aufweist. Durch die Gleit- und Dichtführung wird eine dauerhaft präzise und dichte Lagerung des Stellelements an dem Pumpengehäuse erreicht, womit sich die Lebensdauer der Pumpe erhöht, und es werden darüber hinaus separate Dichtelemente, die mittels Federelementen vorgespannt sind, eingespart.According to the The invention is in a controllable pump with a on a pump housing mounted rotor and an actuator surrounding the rotor, which in the pump housing in the manner of an adjusting piston is slidably mounted, a sliding and sealing guide provided on the pump housing a first sliding surface and on the actuator one on the first sliding surface having a related second sliding surface. Through the sliding And sealing is a permanently accurate and tight bearing of the control element on the pump housing achieved, which increases the life of the pump, and there are also separate sealing elements, the Saved by spring elements, saved.
Gemäß einer besonders bevorzugten Ausgestaltung der Erfindung ist vorgesehen, dass die Gleit- und Dichtführung an dem Pumpengehäuse eine dritte Gleitfläche und an dem Stellelement eine vierte Gleitfläche aufweist, wobei die erste und die dritte Gleitfläche vorzugsweise unterschiedlich ausgebildet sind. Durch eine beidseitige Gleit- und Dichtführung wird eine hohe Präzision erreicht, wobei eine unterschiedliche Ausgestaltung der ersten und der dritten Gleitfläche eine besonders kostengünstige Fertigung erlaubt.According to one particularly preferred embodiment of the invention is provided that the sliding and sealing guide on the pump housing a third sliding surface and on the actuator a fourth Sliding surface, wherein the first and the third sliding surface preferably formed differently. By a bilateral Sliding and sealing guidance becomes a high precision achieved, wherein a different embodiment of the first and the third sliding surface a particularly cost-effective production allowed.
Gemäß einer weiteren bevorzugten Ausgestaltung der Erfindung ist vorgesehen, dass die erste und/oder die dritte Gleitfläche an dem Pumpengehäuse an Gleitelementen ausgebildet sind, die als Einlagen in das Pumpengehäuse integriert sind. Eine solche Ausgestaltung erlaubt es, die Erfindung mit geringen Kosten zu realisieren.According to one further preferred embodiment of the invention is provided that the first and / or the third sliding surface on the pump housing are formed on sliding elements as deposits in the pump housing are integrated. Such a configuration allows the invention to realize with low costs.
Gemäß einer weiteren bevorzugten Ausgestaltung der Erfindung ist das Pumpengehäuse aus Aluminium oder aus einer Aluminiumlegierung gefertigt. Eine solche Ausgestaltung erlaubt es, eine regelbare Pumpe mit einer komplexen Geometrie bei geringen Fertigungskosten herzustellen.According to one Another preferred embodiment of the invention is the pump housing made of aluminum or an aluminum alloy. A Such a design allows a controllable pump with a manufacture complex geometry at low production costs.
Gemäß weiterer bevorzugter Ausgestaltungen der Erfindung ist vorgesehen, dass die Gleitelemente als Gleitplatten aus Stahl, Gusseisenwerkstoffen oder Lagerwerkstoffen gefertigt sind, vorzugsweise aus Stahl 100 Cr 6, Werkzeugstahl C70 oder einer Vollkeramik, insbesondere aus Si3N4. Solche Gleitelemente weisen sowohl eine besonders hohe Dauerhaltbarkeit als auch ein günstiges tribologisches Verhalten auf.According to further preferred embodiments of the invention it is provided that the sliding elements are made as sliding plates made of steel, cast iron materials or bearing materials, preferably of steel 100 Cr 6, tool steel C70 or an all-ceramic, in particular Si 3 N 4. Such gliding Both elements have a particularly high durability as well as a favorable tribological behavior.
Besonders geringe interne Verluste ergeben sich bei einer regelbaren Pumpe dann, wenn – wie gemäß einer weiteren bevorzugten Ausgestaltung der Erfindung vorgesehen – die erste und/oder die dritte Gleitfläche eine fein geschliffene Oberflächenstruktur Rz > 0,5 μm aufweisen und insbesondere mit einer DLC-Beschichtung versehen sind.Especially low internal losses occur with a controllable pump then, if - as according to another preferred embodiment of the invention provided - the first and / or the third sliding surface a finely ground Surface structure Rz> 0.5 μm and in particular provided with a DLC coating.
Weitere vorteilhafte Ausgestaltungen und Weiterbildungen der Erfindung ergeben sich aus den Unteransprüchen sowie aus der Beschreibung im Zusammenhang mit den Zeichnungen.
