Abstract
Description
Die vorliegende Erfindung betrifft ein Umschaltventil zum Steuern eines Fluidstroms und einen Verbrennungsmotor mit einem derartigen Umschaltventil.The present invention relates to a switching valve for controlling a fluid flow and an internal combustion engine having such a switching valve.
Obwohl auf beliebige Fahrzeuge anwendbar, werden die vorliegende Erfindung sowie die ihr zugrunde liegende Problematik in Bezug auf ein Personenkraftfahrzeug näher erläutert.Although applicable to any vehicle, the present invention and the underlying problem with respect to a passenger car will be explained in more detail.
Bei Verbrennungsmotoren wirkt sich ein hohes Verdichtungsverhältnis positiv auf den Wirkungsgrad des Verbrennungsmotors aus. Unter Verdichtungsverhältnis wird im Allgemeinen das Verhältnis des gesamten Zylinderraumes vor der Verdichtung zum verbliebenen Zylinderraum nach der Verdichtung verstanden. Bei Verbrennungsmotoren mit Fremdzündung, insbesondere Ottomotoren, die ein festes Verdichtungsverhältnis aufweisen, darf das Verdichtungsverhältnis jedoch nur so hoch gewählt werden, dass bei Volllastbetrieb ein so genanntes ”Klopfen” des Verbrennungsmotors vermieden wird. Jedoch könnte für den weitaus häufiger auftretenden Teillastbereich des Verbrennungsmotors, also bei geringer Zylinderfüllung, das Verdichtungsverhältnis mit höheren Werten gewählt werden, ohne dass ein ”Klopfen” auftreten würde. Der wichtige Teillastbereich eines Verbrennungsmotors kann verbessert werden, wenn das Verdichtungsverhältnis variabel einstellbar ist. Zur Verstellung des Verdichtungsverhältnisses sind verschiedene Systeme beschrieben.In internal combustion engines, a high compression ratio has a positive effect on the efficiency of the internal combustion engine. Under compression ratio is generally understood the ratio of the entire cylinder space before compression to the remaining cylinder space after compression. In internal combustion engines with spark ignition, in particular gasoline engines, which have a fixed compression ratio, the compression ratio, however, may only be selected so high that so-called "knocking" of the internal combustion engine is avoided during full-load operation. However, for the much more frequently occurring partial load range of the internal combustion engine, ie with low cylinder filling, the compression ratio with higher values could be selected without "knocking" occurring. The important part load range of an internal combustion engine can be improved if the compression ratio is variably adjustable. Various systems are described for adjusting the compression ratio.
Die
Somit liegt der vorliegenden Erfindung die Aufgabe zugrunde, ein verbessertes Umschaltventil zu schaffen, welches die oben genannten Nachteile beseitigt.Thus, the present invention has for its object to provide an improved changeover valve, which eliminates the disadvantages mentioned above.
Diese Aufgabe wird erfindungsgemäß durch ein Umschaltventil mit den Merkmalen des Patentanspruchs 1 und/oder durch einen Verbrennungsmotor mit den Merkmalen des Patentanspruchs 7 gelöst.This object is achieved by a switching valve with the features of
Demgemäß sind vorgesehen:
Ein Umschaltventil, insbesondere zum Steuern eines Fluidstroms, wobei das Umschaltventil wahlweise in eine erste und eine zweite Schaltstellung verlagerbar ist, wodurch jeweils ein erster Arbeitsraum bzw. ein zweiter Arbeitsraum mit einem Volumen in Fluidverbindung bringbar ist.Accordingly, it is provided:
A switching valve, in particular for controlling a fluid flow, wherein the switching valve is selectively displaceable in a first and a second switching position, whereby in each case a first working space or a second working space can be brought into fluid communication with a volume.
Ein Verbrennungsmotor, welcher ein einstellbares Verdichtungsverhältnis aufweist, mit: einem derartigen Umschaltventil; und einer Pleuelstangenanordnung mit einer in einem Pleuellagerauge und/oder einem Hublagerauge angeordneten hydraulisch verstellbaren Exzentereinrichtung zur Verstellung einer effektiven Pleuelstangenlänge, wobei ein Verstellweg der Exzentereinrichtung mittels des Umschaltventils steuerbar ist.An internal combustion engine having an adjustable compression ratio, comprising: such a switching valve; and a connecting rod assembly with a arranged in a connecting rod eye and / or a Hublagerauge hydraulically adjustable eccentric means for adjusting an effective connecting rod length, wherein an adjustment of the eccentric means of the switching valve is controllable.
Die Grundidee der vorliegenden Erfindung besteht darin, ein Umschaltventil vorzusehen, welches wahlweise in eine erste und eine zweite Schaltstellung verlagerbar ist, wodurch jeweils ein erster Arbeitsraum bzw. ein zweiter Arbeitsraum mit einem Volumen in Fluidverbindung bringbar ist.The basic idea of the present invention is to provide a switching valve which can be displaced optionally into a first and a second switching position, whereby a respective first working space or a second working space can be brought into fluid communication with a volume.
In den Unteransprüchen finden sich vorteilhafte Ausgestaltungen und Verbesserungen des im Patentanspruch 1 angegebenen Umschaltventils bzw. des im Patentanspruch 7 angegebenen Verbrennungsmotors.In the dependent claims are advantageous refinements and improvements of the specified in
Gemäß einer bevorzugten Weiterbildung weist das Umschaltventil eine Fluidnut zur Herstellung der Fluidverbindung des ersten bzw. zweiten Arbeitsraums mit dem Volumen auf. Dies ermöglicht vorteilhaft eine einfache Herstellung des Umschaltventils und gleichzeitig ein einfaches Umschalten von der ersten Schaltstellung in die zweite Schaltstellung.According to a preferred development, the switching valve has a fluid groove for establishing the fluid connection of the first or second working space with the volume. This advantageously allows a simple production of the changeover valve and at the same time a simple switching from the first switching position to the second switching position.
Gemäß einem weiteren bevorzugten Ausführungsbeispiel ist eine Verlagerung des Umschaltventils in die jeweilige Schaltstellung durch einen Betätigungsdruck bzw. Schaltdruck auf das Umschaltventil auslösbar, wodurch ein definiertes und kontrolliertes Verlagern möglich ist. Die Begriffe „Betätigungsdruck” und „Schaltdruck” sollen gleichbedeutend verwendet werden.According to a further preferred embodiment, a displacement of the switching valve in the respective switching position by an actuating pressure or switching pressure on the switching valve can be triggered, whereby a defined and controlled displacement is possible. The terms "operating pressure" and "switching pressure" are to be used synonymously.
Gemäß einer weiteren bevorzugten Ausführungsform ist der Betätigungsdruck durch einen Fluiddruck aufbringbar. Hierdurch ist das Verlagern des Umschaltventils in einfach kontrollierbarer Weise ausführbar.According to a further preferred embodiment, the actuation pressure can be applied by a fluid pressure. As a result, the displacement of the switching valve in an easily controllable manner executable.
Gemäß einer weiteren bevorzugten Weiterbildung ist zum Verlagern des Umschaltventils in die erste und die zweite Schaltstellung jeweils ein bestimmter Fluiddruck aufbringbar. Dies ermöglicht ein zuverlässiges und sicheres Umschalten von der ersten in die zweite Schaltstellung und umgekehrt, wodurch sich die Zuverlässigkeit des Umschaltventils erhöht, da das Umschalten von einem bestimmten vorbestimmbaren und steuerbaren Druckwert abhängt. According to a further preferred development, in each case a specific fluid pressure can be applied for displacing the switching valve into the first and the second switching position. This allows a reliable and safe switching from the first to the second switching position and vice versa, whereby the reliability of the switching valve increases, since the switching depends on a certain predeterminable and controllable pressure value.
Gemäß einem weiteren bevorzugten Ausführungsbeispiel ist das Umschaltventil mittels einer mit dem Umschaltventil gekoppelten Federeinrichtung derart ausgebildet, dass ein Betätigen des Umschaltventils erst bei einem Betätigungsdruck oberhalb eines vorbestimmten Druck-Schwellenwertes erfolgt. Dies verhindert zuverlässig ein ungewolltes Schalten des Umschaltventils, wodurch dessen Zuverlässigkeit erhöht wird.According to a further preferred embodiment, the switching valve is formed by means of a spring device coupled to the switching valve such that actuation of the switching valve takes place only at an actuating pressure above a predetermined pressure threshold value. This reliably prevents accidental switching of the switching valve, thereby increasing its reliability.
Gemäß einer weiteren bevorzugten Weiterbildung ist das Umschaltventil in die Pleuelstangenanordnung, insbesondere in einen Bereich des Hublagerauges, integriert, wodurch das Umschaltventil nur geringen Bauraum einnimmt. Hierdurch wird der Einsatzbereich des Umschaltventils vorteilhaft erweitert.According to a further preferred development, the changeover valve is integrated in the connecting rod arrangement, in particular in a region of the lifting bearing eye, whereby the changeover valve takes up only small installation space. As a result, the range of application of the changeover valve is advantageously extended.
Gemäß einer bevorzugten Ausführungsform ist der Betätigungsdruck durch einen Motoröldruck aufbringbar, wobei der Verbrennungsmotor Mittel, beispielsweise eine regelbare Ölpumpe oder einen Druckspeicher oder eine Zusatzölpumpe, zum dauerhaften Erhöhen des Motoröldrucks aufweist. Dies ermöglicht vorteilhaft eine Integration des Umschaltventils in vorhandene Motorölsysteme, wodurch der Einsatzbereich des Umschaltventils erweitert wird.According to a preferred embodiment, the actuation pressure can be applied by an engine oil pressure, the combustion engine having means, for example a controllable oil pump or a pressure accumulator or an additional oil pump, for permanently increasing the engine oil pressure. This advantageously makes it possible to integrate the changeover valve into existing engine oil systems, thereby widening the range of use of the changeover valve.
