Description
Die Erfindung betrifft fördermengenregelbare Schmierölpumpen von Verbrennungsmotoren mit hydraulischer Fördermengenregelung durch einen Regelkolben.The The invention relates to flow-adjustable lubricating oil pumps of internal combustion engines with hydraulic flow control by a Control piston.

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. Dieser Nachteil kann durch eine stärkere Verschiebefeder mit für den Förderdruck erhöhtem Druckregelniveau, dann jedoch mit geringeren Verbrauchsvorteilen, kompensiert werden.While through a weakly designed displacement spring a consumption advantage relatively low discharge pressure, For example, 1.5 bar in the lower speed range of the engine through the control piston is adjustable, causes the low force of the shift spring However disadvantageous a relatively slow oil pump adjustment at a delivery volume increase. hereby can with fast speed drops of the engine with then required Nachregelbedarf the control oil pump by a too low Adjustment speed for a short time the reliable oil pressure level be fallen below. This disadvantage can be achieved by a stronger displacement spring with for the delivery pressure increased Pressure control level, but then with lower fuel consumption, be compensated.
Der vorliegenden Erfindung liegt die Aufgabe zugrunde, eine fördermengenregelbare Schmierölpumpe mit einem Druckregelbereich bis hin zu niedrigen Förderdrücken durch die Verwendung einer relativ schwachen Verschiebefeder des Fördermengenreglers auszuführen, ohne dass nachteilig eine geringere Verstellgeschwindigkeit bei erforderlichen Fördermengenverstellungen in Kauf genommen werden muss.Of the present invention is based on the object, a flow rate adjustable Lubricating oil pump with a pressure control range through to low delivery pressures the use of a relatively weak displacement spring of the flow regulator perform, without disadvantageously a lower adjustment speed required flow rate adjustments must be accepted.

Die erfindungsgemäße Ausbildung von Regelölpumpen mit zwei unterschiedlich großen, hydraulischen Wirkflächen des Fördermengenreglers ermöglicht eine hydraulische Rückstellkraft zur Unterstützung der Verschiebefeder des Fördermengenreglers. Hierdurch wird auch bei einer verbrauchvorteilhaft schwach ausgeführten Rückstellfeder eine schnelle Fördermengenverstellung der Regelölpumpe im Sinne einer Fördermengenerhöhung erreicht.The inventive training of control oil pumps with two different sizes, hydraulic active surfaces the flow rate controller allows a hydraulic restoring force for support the displacement spring of the flow rate controller. As a result, even with a fuel consumption advantageous poorly executed return spring a fast flow adjustment the regular oil pump reached in the sense of an increase in delivery volume.
