Abstract
Description
Die Erfindung betrifft ein Volumenstromregelventil.The invention relates to a volume flow control valve.
Solche Volumenstromregelventile werden insbesondere zur Regelung des Kraftstoffvolumenstroms im Zulauf zu einer Hochdruckpumpe, die Kraftstoff in einen Hochdruckspeicher eines Common-Rail-Einspritzsystems einer Brennkraftmaschine fördert eingesetzt. Das Volumenstromregelventil muss zum einen gewährleisten, dass ständig genügend Kraftstoff entsprechend den Betriebsbedingungen der Brennkraftmaschine zur Verfügung steht. Zum anderen soll jedoch nicht übermäßig viel Kraftstoff in den Hochdruckspeicher gepumpt werden, da der überschüssige Kraftstoff über ein Hochdruckventil in den Tank der Brennkraftmaschine zurückgeführt wird und somit zu einer Erwärmung des Kraftstoffes im Tank führt. Zudem verringert sich durch das Verdichten von nicht benötigtem Kraftstoff der Wirkungsgrad des Einspritzsystems.Such volume flow control valves are particularly to regulate the fuel volume flow in the inlet to a high pressure pump, the fuel in a high-pressure accumulator of a common rail injection system promotes an internal combustion engine used. On the one hand, the volume flow control valve must ensure that constantly enough Fuel according to the operating conditions of the internal combustion engine to disposal stands. On the other hand, there should not be excessive fuel in the High pressure accumulators are pumped because the excess fuel is over one High pressure valve is returned to the tank of the internal combustion engine and thus to warming of fuel in the tank. It also reduces fuel consumption by compressing it the efficiency of the injection system.

Um zwei unterschiedliche Steigungen
in der Ventilkennlinie zu erreichen wir in der
Die Aufgabe der Erfindung ist es daher, ein Volumenstromregelventil bereitzustellen, das einfach und kostengünstig zu fertigen ist und das unterschiedlich Steigungen der Ventilkennlinie ermöglicht.The object of the invention is therefore, to provide a flow control valve that is simple and economical is to be manufactured and that different slopes of the valve characteristic allows.
Die Aufgabe wird gelöst durch die Merkmale des unabhängigen Patentanspruchs. Vorteilhafte Ausgestaltungen der Erfindung sind in den Unteransprüchen gekennzeichnet.The task is solved by the characteristics of the independent Claim. Advantageous embodiments of the invention are in the subclaims characterized.
Die Erfindung zeichnet sich dadurch aus, dass der Steuerkolben als Stufenkolben ausgebildet ist, der außen umströmt wird und in seiner Mantelfläche eine Steuergeometrie aufweist, die derart ausgebildet ist, dass sich in Abhängigkeit von der Stellung des Steuerkolbens unterschiedliche Steigungen in der Ventilkennlinie ergeben. Der Vorteil der Erfindung liegt darin, dass auch komplizierteste Steuergeometrien beispielsweise durch Fräsen einfach in die Mantelfläche des Stufenkolbens eingebracht werden können. Ein Entgraten der Steuergeometrie ist problemlos möglich, da sich die Kante an der Mantelfläche des Steuerkolbens befindet und hierdurch gut zugänglich ist. Durch das einfache Herstellen auch komplizierter Steuergeometrien lassen sich kostengünstig unterschiedlichste Ventilkennlinien realisieren. Der Ein- und Auslass kann durch einfache und preiswerte Bohrungen in das Ventilgehäuse hergestellt werden.The invention is characterized by this from that the control piston is designed as a stepped piston, the Outside flows around and in its outer surface has a control geometry which is designed such that yourself in dependence different slopes in the position of the control piston Valve characteristic curve result. The advantage of the invention is that even the most complicated control geometries are possible mill simply in the outer surface of the stepped piston can be introduced. Deburring the control geometry is easily possible because the edge is on the outer surface of the control piston and thus easily accessible is. By simply manufacturing even complex control geometries can be inexpensive Realize a wide variety of valve characteristics. The inlet and outlet can be made through simple and inexpensive holes in the valve housing become.
Da sich die Steigung der Ventilkennlinie allein durch die Steuergeometrie ergibt, kann der Kolbenhub proportional zum Ansteuersignal erfolgen. Ein proportionaler Zusammenhang zwischen Kolbenhub und Ansteuersignal lässt sich mit einfachen und kostengünstigen Stellgliedern beispielsweise einem elektromagnetischem Stellglied erreichen.Because the slope of the valve characteristic The piston stroke can be proportional solely by the control geometry to the control signal. A proportional relationship between Piston stroke and control signal leaves deal with simple and inexpensive Actuators, for example, an electromagnetic actuator to reach.
Eine bevorzugte Ausgestaltung der Erfindung sieht vor, die Abströmgeometrie mehrfach radial über den Umfang verteilt in den Steuerkolben einzubringen. Hierdurch lässt sich der Durchfluss erhöhen und zusätzlich werden die Radialkräfte auf den Ventilkolben reduziert.A preferred embodiment of the Invention provides for the outflow geometry several times over radially distribute the circumference distributed in the control piston. hereby let yourself increase the flow and additionally are the radial forces reduced to the valve piston.
