Abstract
Description
Die Erfindung betrifft eine Druckregelvorrichtung mit den Merkmalen aus dem Oberbegriff des Patentanspruchs 1.The The invention relates to a pressure control device having the features from the preamble of claim 1.
Die
Erfindung geht von der deutschen Offenlegungsschrift
Da der Schmiermittelbedarf einer Brennkraftmaschine jedoch nicht nur temperatur-, sondern auch drehzahlabhängig ist, ist es von Nachteil, dass die Drehzahlabhängigkeit bei der gattungsgemäßen Druckregeleinheit nicht berücksichtigt ist.There However, the lubricant requirement of an internal combustion engine not only temperature, but also speed-dependent, it is disadvantageous that the speed dependency in the generic pressure control unit not considered is.

ist aus der deutschen Patentschrift
Aufgabe der vorliegenden Erfindung ist es, eine drehzahlabhängige Druckregelvorrichtung für eine Schmiermittelpumpe aufzuzeigen, die gleichzeitig einen äußerst einfachen und robusten Aufbau aufweist.task The present invention is a speed-dependent pressure control device for one Lubricant pump show that at the same time a very simple and has a robust construction.
Diese Aufgabe wird durch die Merkmale im kennzeichnenden Teil des Patentanspruchs 1 gelöst.These The object is achieved by the features in the characterizing part of the claim 1 solved.
Durch die erfindungsgemäße Ausgestaltung wird eine äußerst einfache, robuste, d. h. störunanfällige und extrem kostengünstige passive Druckregelvorrichtung erzielt. Da keine aktiven Bauelemente für die Drehzahlerfassung zum Einsatz kommen, ist das Ausfallrisiko der Druckregelvorrichtung äußerst gering. Darüber hinaus sind die Anforderungen an das Package für die erfindungsgemäße Druckregelvorrichtung sehr gering.By the embodiment of the invention will an extremely simple, robust, d. H. non-susceptible and extremely inexpensive achieved passive pressure control device. There are no active components for the Speed detection are used, the risk of failure of the Pressure regulator extremely low. About that In addition, the requirements for the package for the pressure control device according to the invention very low.
Durch die Ausgestaltung gemäß Patentanspruch 2 kann die resultierende Druckregelkennlinie an den drehzahlabhängigen Schmiermittelbedarf der Rotationsmaschine angepasst werden, insbesondere kann ein zu starkes Ansteigen des Drucks bei hohen Drehzahlen verhindert werden.By the embodiment according to claim 2, the resulting pressure control characteristic to the speed-dependent lubricant requirement be adapted to the rotary machine, in particular, one to strong increase in pressure can be prevented at high speeds.
Durch die Variation der Durchflussquerschnitte gemäß Patentanspruch 3 ist neben der drehzahlabhängigen Druckregelung auch eine temperaturabhängige Regelung der Schmiermittelfördermenge möglich, wobei die Bauteil- und/oder Schmiermitteltemperatur als Regelgröße dient.By the variation of the flow cross sections according to claim 3 is in addition the speed-dependent Pressure control also a temperature-dependent control of the lubricant flow possible, wherein the component and / or Lubricant temperature is used as a controlled variable.
Die Wellen gemäß Patentanspruch 4 sind besonders bevorzugte Ausführungsbeispiele.The Shafts according to claim 4 are particularly preferred embodiments.
Die Ausführungen gemäß Patentanspruch 5 sind ebenfalls besonders bevorzugte Ausführungsvarianten.The versions according to claim 5 are also particularly preferred embodiments.
Die Ausgestaltung gemäß Patentanspruch 6 ist eine besonders bevorzugte Variante, mit der die Drehzahlabhängigkeit der Druckregelvorrichtung nochmals verbessert wird.The Embodiment according to claim 6 is a particularly preferred variant with which the speed dependence the pressure control device is further improved.
Im Folgenden ist die Erfindung für ein besonders bevorzugtes Ausführungsbeispiel anhand von zwei Figuren näher erläutert.in the The following is the invention for a particularly preferred embodiment closer by two figures explained.
