Abstract
Description
Die Erfindung betrifft fördermengenregelbare Schierölpumpen von Verbrennungsmotoren mit hydraulischer Fördermengenregelung durch einen Regelkolben.The Invention relates to controllable oil pumps of internal combustion engines with hydraulic flow control by a Control piston.
Eine derartige Schmierölpumpe ist als Außenzahnrad-Regelölpumpe aus der deutschen Anmeldung mit dem Aktenzeichen AZ10237801.0 (17.08.2002) bekannt. Sie weist als Fördermengenregler eine Verschiebeeinheit mit axial veränderlichem Zahneingriff der Förderzahnräder auf, die einerseits vom Förderdruck und gegenüberliegend andererseits von der Kraft einer als Verschiebefeder bezeichneten Rückstellfeder sowie durch einen Regelkolben mit Steuerdruck beaufschlagt wird. Die Auslegungskraft der Verschiebefeder bestimmt für den Förderdruck das unterste Druckregelniveau der Regelölpumpe, über die Höhe des in der Federkammer wirkenden Steuerdruckes wird der Förderdruck im Druckregelbereich der Regelölpumpe variiert.A such oil pump is off as an external gear control oil pump the German application with the file number AZ10237801.0 (08/17/2002) known. It shows as a flow regulator a displacement unit with axially variable tooth engagement Conveyor gears on, the one hand from the delivery pressure and opposite on the other hand by the force of one called a displacement spring Return spring as well as by a control piston with control pressure. The design force of the displacement spring determines the delivery pressure the lowest pressure control level of the control oil pump, above the level of the one acting in the spring chamber Control pressure becomes the delivery pressure in the pressure control range of the control oil pump varied.
Während durch eine schwach ausgelegte Verschiebefeder verbrauchsvorteilhaft ein relativ niedriger Förderdruck, beispielsweise 1,5 bar im unteren Drehzahlbereich des Verbrennungsmotors, durch den Regelkolben einstellbar ist, bewirkt die geringe Kraft der Verschiebefeder jedoch nachteilig eine relativ langsame Ölpumpenverstellung bei einer Fördermengenerhöhung. Hierdurch kann bei schnellen Drehzahlabsenkungen des Verbrennungsmotors mit dann erforderlichem Nachregelbedarf der Regelölpumpe durch eine zu geringe Verstellgeschwindigkeit kurzzeitig das betriebssichere Öldruckniveau unterschritten werden.While through a weakly designed displacement spring is advantageous in terms of consumption relatively low delivery pressure, for example 1.5 bar in the lower speed range of the internal combustion engine the control piston is adjustable, causes the low force of the displacement spring however, disadvantageous is a relatively slow oil pump adjustment when the delivery rate is increased. hereby can with fast speed reductions of the internal combustion engine with then the need for readjustment of the control oil pump due to too little Adjustment speed briefly the reliable oil pressure level be undercut.
Dieser Nachteil kann durch eine stärkere Verschiebefeder mit für den Förderdruck erhöhtem Druckregelniveau, dann jedoch mit geringeren Verbrauchsvorteilen, kompensiert werden.This Disadvantage can be due to a stronger displacement spring with for the delivery pressure increased pressure control level, then, however, with lower consumption advantages.
Der vorliegenden Erfindung liegt die Aufgabe zugrunde, eine fördermengenregelbare Schmierölpumpe mit einem Druckregelbereich bis hin zu niedrigen Förderdrücken durch die Verwendung einer relativ schwachen Rückstellfeder des Fördermengenreglers auszuführen, ohne dass nachteilig eine geringere Verstellgeschwindigkeit bei erforderlichen Fördermengenverstellungen in Kauf genommen werden muss.The The present invention has for its object a controllable delivery rate Lubricating oil pump with a pressure control range down to low delivery pressures the use of a relatively weak return spring of the flow regulator perform, without adversely affecting a lower adjustment speed necessary flow rate adjustments must be accepted.
Diese Aufgabe wird erfindungsgemäß durch die Verwendung eines Fördermengenreglers mit zwei unterschiedlich großen, hydraulischen Wirkflächen gemäß Anspruch 1 gelöst.This The object is achieved by the Use of a flow regulator with two different sizes, hydraulic active surfaces according to claim 1 solved.

Die erfindungsgemäße Ausbildung von Regelölpumpen mit zwei unterschiedlich großen, hydraulischen Wirkflächen des Fördermengenreglers ermöglicht eine hydraulische Rückstellkraft zur Unterstützung der Rückstellfeder des Fördermengenreglers. Hierdurch wird auch bei einer verbrauchvorteilhaft schwach ausgeführten Rückstellfeder eine schnelle Fördermengenverstellung der Regelölpumpe im Sinne einer Fördermengenerhöhung erreicht.The Training according to the invention of control oil pumps with two different sizes, hydraulic active surfaces of the flow rate regulator enables a hydraulic restoring force for support the return spring of the flow regulator. As a result, the return spring is also weakly designed for consumption a fast delivery rate adjustment the control oil pump achieved in the sense of an increase in output.
