Abstract
Description
Die Erfindung betrifft ein temperaturabhängig schaltbares Druckregelventil, insbesondere zur Verwendung in einem Kühlmittelkanal einer Kolbenkühlung einer Brennkraftmaschine, umfassend ein Ventilgehäuse mit einem Einlass, einem Auslass und einem sich zwischen Einlass und Auslass erstreckenden Strömungskanal, einen Sperrkörper zum Öffnen und Schließen des Strömungskanals sowie ein Federelement zur Beaufschlagung des Sperrkörpers in Schließrichtung.The The invention relates to a temperature-dependent switchable pressure control valve, in particular for use in a coolant channel of a Piston cooling of an internal combustion engine, comprising a valve housing with one inlet, one outlet and one between inlet and outlet extending flow channel, a blocking body for opening and closing the flow channel and a spring element for acting on the locking body in the closing direction.

Eine
Weiterentwicklung dieser Kolbenkühlung ist mit der
Aufgabe der Erfindung ist es daher, ein eingangs genanntes Druckregelventil bereit zu stellen, das einerseits eine temperaturabhängig Schaltung und andererseits zugleich eine druckabhängige Regelung ermöglicht.task The invention is therefore an initially mentioned pressure control valve to provide, on the one hand, a temperature-dependent Circuit and on the other hand at the same time a pressure-dependent Regulation possible.
Die Lösung der Aufgabe erfolgt mit einem Druckregelventil mit den Merkmalen des Anspruchs 1, wobei erfindungsgemäß ein mit dem Sperrkörper zusammenwirkendes temperaturabhängig schaltbares Verriegelungselement vorgesehen ist. Dadurch wird eine temperaturabhängige Schaltung zwischen eines Öffnungs- und einer Schließstellung und außerdem in der Öffnungsstellung eine druckabgängige Regelung des Strömungsmittels erreicht. Bei Verwendung in einem Kühlmittelkanal einer Kolbenkühlung einer Brennkraftmaschine wird so insbesondere auch bei hohen Brennkraftmaschinendrehzahlen eine ausreichende Kühlung der Kolben gewährleistet.The Solution of the task is done with a pressure control valve the features of claim 1, wherein according to the invention a with the locking body cooperating temperature dependent switchable locking element is provided. This will be a temperature-dependent circuit between an opening and a closed position and also in the open position a pressure-dependent regulation of the fluid reached. When used in a coolant channel a Piston cooling of an internal combustion engine is so in particular at high engine speeds sufficient cooling the piston ensured.
Besonders zu bevorzugende Ausführungsbeispiele und Weiterbildungen sind Gegenstand der Unteransprüche.Especially preferred embodiments and developments are the subject of the dependent claims.
Vorzugsweise ist der Sperrkörper mittels des Verriegelungselements unterhalb einer vorgegebenen Temperatur des wenigstens einen Verriegelungselements in seiner Schließstellung verriegelbar, sodass unterhalb dieser Temperatur unabhängig vom anliegenden Strömungsmitteldruck der Strömungskanal des Druckregelventils geschlossen ist. Dadurch wird bei Verwendung in einem Kühlmittelkanal einer Kolbenkühlung einer Brennkraftmaschine bei kalter Brennkraftmaschine eine unnötige Kolbenkühlung unterbunden und es baut sich der für Lagerstellen der Brennkraftmaschine erforderliche Schmiermitteldruck schneller auf. Ein stark verringerter Verschleiß und damit eine erhöhte Lebensdauer der Brennkraftmaschine können auf diese Weise erreicht werden.Preferably the locking body is below by means of the locking element a predetermined temperature of the at least one locking element Lockable in its closed position, so below this temperature regardless of the applied fluid pressure the flow channel of the pressure regulating valve is closed. Thereby when used in a coolant channel of a piston cooling an internal combustion engine with a cold internal combustion engine an unnecessary Piston cooling prevented and it builds up for Bearing locations of the engine required lubricant pressure faster. A greatly reduced wear and therefore an increased life of the internal combustion engine can be achieved in this way.
Einer besonders vorteilhaften Ausführung der Erfindung zufolge ist bei Überschreiten einer vorgegebenen Temperatur des wenigstens einen Verriegelungselements der Sperrkörper zur Bewegung zwischen seiner Schließstellung und seiner Öffnungsstellung freigebbar, sodass oberhalb dieser Temperatur der Sperrköper abhängig vom anliegenden Strömungsmitteldruck den Strömungskanal des Druckregelventils öffnet oder schließt, wobei der Strömungsmitteldruck gegen das Federelement wirkt, die Regelkurve also im Wesentlichen vom Strömungsmitteldruck und der Kennlinie des Federelements abhängt.one According to particularly advantageous embodiment of the invention is at a predetermined temperature of the at least one locking element of the locking body for movement between its closed position and its open position releasable, so above this temperature, the Sperrköper depending on the applied fluid pressure opens the flow channel of the pressure control valve or closes, wherein the fluid pressure acts against the spring element, so the control curve essentially from the fluid pressure and the characteristic of the spring element depends.
Sehr zweckmäßig ist es, wenn das wenigstens eine Verriegelungselement im Wesentlichen aus einer Formgedächtnislegierung (shape memory alloy, SMA) besteht. Das Verriegelungselement weist dadurch ein besonderes spezifisches Arbeitsvermögen (Verhältnis von geleisteter Arbeit zu Werkstoffvolumen) auf und ist in der Lage, eine sehr hohe Anzahl von Bewegungszyklen ohne nennenswerte Ermüdung durchzuführen. Alternativ kann das wenigstens eine Verriegelungselement im Wesentlichen aus einer Bimetallverbindung bestehen, dies ermöglicht eine besonders kostengünstige Ausführung.Very it is expedient if the at least one locking element essentially of a shape memory alloy (shape memory alloy, SMA). The locking element has characterized a special specific working capacity (ratio from work done to material volume) and is able to a very high number of motion cycles without appreciable fatigue perform. Alternatively, the at least one locking element essentially consist of a bimetallic connection, this allows a particularly cost-effective design.
Bevorzugterweise verriegelt das wenigstens eine Verriegelungselement in Verriegelungsstellung den Sperrkörper formschlüssig, dabei hat es sich als günstig erwiesen, das wenigstens eine Verriegelungselement rasthakenförmig auszugestalten. Auch eine reibschlüssige Verriegelung des Sperrkörpers durch das Verriegelungselement in Verriegelungsstellung wird als vorteilhaft angesehen.preferably, locks the at least one locking element in the locked position the Locking body form-fitting, it has to be cheap proved, the at least one locking element rashakenförmig embody. Also a frictional locking of the Locking body by the locking element in the locked position is considered advantageous.
