Abstract
Description
Die Erfindung betrifft ein Thermostatventil für eine Kühlanlage eines Verbrennungsmotors mit einem in einer Mischkammer anzuordnenden thermostatischen Arbeitselement, das als Antriebselement für ein zwischen der Mischkammer und einem Anschluss von einem Kühlmittelkühler anzuordnenden Hauptventilelement und für zwei Kurzschlussventilelemente dient, die vor der Mischkammer anzuordnen sind und die derart relativ zu einem Ventilsitz angeordnet sind, dass bei einer Ausfahrbewegung des thermostatischen Arbeitselementes das zunächst geschlossene Kurzschlussventilelement öffnet und das andere aufgrund einer Schiebereinheit bei weiterer Ausfahrbewegung wieder schließt.The The invention relates to a thermostatic valve for a cooling system of an internal combustion engine with a thermostatic working element to be arranged in a mixing chamber, as the driving element for a main valve element to be disposed between the mixing chamber and a port of a coolant radiator and for serves two short-circuit valve elements, which are to be arranged in front of the mixing chamber and which are arranged relative to a valve seat such that in an extension movement of the thermostatic working element the first closed short-circuit valve element opens and the other due a slide unit closes again on further extension movement.
Ein
bekanntes Thermostatventil der eingangs genannten Art (
Der Erfindung liegt die Aufgabe zugrunde, das Thermostatventil der eingangs genannten Art konstruktiv zu vereinfachen und darüber hinaus die Funktionssicherheit zu erhöhen.Of the Invention is based on the object, the thermostatic valve of the beginning constructively simplify this type and beyond to increase the functional reliability.
Diese Aufgabe wird dadurch gelöst, dass ein gemeinsames Kurzschlussventilelement vorgesehen ist, das einen als Kurzschlussventilschieber dienenden Abschnitt und einen in Ausfahrrichtung des thermostatischen Arbeitselementes vorgeschalteten Kurzschlussventilteller aufweist, zwischen denen ein gemeinsamer Ventilsitz vorgesehen ist, und dass in dem gemeinsamen Ventilsitz ein zur Mischkammer hin öffnendes Überdruckventil vorgesehen ist.These Task is solved by in that a common short-circuit valve element is provided, which a serving as a short-circuit valve spool portion and a in the extension direction of the thermostatic working element upstream short-circuit valve plate between which a common valve seat is provided, and that in the common valve seat opening to the mixing chamber over pressure relief valve is provided.
Mittels des gemeinsamen Kurzschlussventilelementes lässt sich die Zahl der Bauteile reduzieren. Da eines der Ventilelemente als Kurzschlussventilschieber ausgebildet ist, kann auf eine Feder verzichtet werden. Außerdem wird sichergestellt, dass dann, wenn in kaltem Zustand die Motordrehzahl erhöht wird, keine thermischen und/oder mechanischen Beschädigungen an dem Verbrennungsmotor oder zugehörigen Komponenten auftreten. Hierfür ist das Überdruckventil vorgesehen, das bei einem erhöhten Druck die Durchströmung des Kühlmittels von dem Motoraustritt zum Motoreintritt freigibt.through the common short-circuit valve element can be the number of components to reduce. As one of the valve elements as a short-circuit valve spool is formed, can be dispensed with a spring. In addition, will ensured that when in cold condition the engine speed is increased, no thermal and / or mechanical damage to the internal combustion engine or associated Components occur. Therefor is the pressure relief valve provided that at an elevated pressure the flow of the coolant from the engine exit to the engine entrance releases.
In Ausgestaltung der Erfindung wird vorgesehen, dass der gemeinsame Ventilsitz von einem ringförmigen Bauteil gebildet wird, das einen dichtend in einen Motorblock oder Zylinderkopf einsetzbaren Abschnitt und einen nach innen ragenden Ringsteg aufweist, dessen innerer Rand als Ventilsitz für den Kurzschlussventilschieber und als Ventilsitz für den Kurzschlussventilteller dient. Dadurch wird es möglich, das Thermostat ventil als eine vorgefertigte Baueinheit auszubilden, die als solche in einen Verbrennungsmotor eingebaut werden kann, ohne dass an dem Verbrennungsmotor Bearbeitungen, insbesondere für das Kurzschlussventil, beispielsweise für eine Auflagefläche einer Feder, vorgesehen werden müssen.In Embodiment of the invention is provided that the common Valve seat of an annular Component is formed, which sealingly into an engine block or Cylinder head insertable section and an inwardly projecting annular web whose inner edge serves as a valve seat for the short-circuit valve spool and as a valve seat for serves the short-circuit valve disk. This will make it possible Form thermostatic valve as a prefabricated unit, which can be installed as such in an internal combustion engine, without machining operations on the internal combustion engine, in particular for the short-circuit valve, for example for a bearing surface a spring, must be provided.
In weiterer Ausgestaltung der Erfindung wird vorgesehen, dass der Ringsteg des Bauteils mit Durchbrechungen versehen ist, die auf der Seite der Mischkammer mit einem Überdruckventilring abgedeckt sind, der mit einer Überdruckventilfeder belastet ist.In Further embodiment of the invention it is provided that the annular web the component is provided with openings on the side the mixing chamber with a pressure relief valve ring are covered with a pressure relief spring is charged.
In weiterer Ausgestaltung der Erfindung wird vorgesehen, dass die Überdruckventilfeder an dem gemeinsamen Kurzschlussventilelement abgestützt ist. Dadurch ist es möglich, der Überdruckventilfeder eine zusätzliche Funktion zu geben, nämlich die Funktion einer ergänzenden Rückstellfeder, die benötigt wird, wenn ein Leerweg zwischen dem thermostatischen Arbeitselement und dem Hauptventilelement vorgesehen ist.In Further embodiment of the invention it is provided that the pressure relief spring is supported on the common short-circuit valve element. This makes it possible the pressure relief spring a additional To give function, namely the function of a supplementary Return spring which needed when there is a free path between the thermostatic working element and the main valve element is provided.
