Description
Die vorliegende Erfindung behandelt ein Ventil zum stirnseitigen Abschluss eines in Hubrichtung des Dichtelements liegenden Dichtsitzes, insbesondere ein Regenerierventil für eine Tankentlüftungsanlage bei Kraftfahrzeugen, mit einem Magnetanker und einer Rückstellfeder, wobei das Dichtelement zumindest teilweise von einer Flachfeder geführt ist, die von einem Siebblech umgeben ist.The present invention deals with a valve for the end closure a sealing seat lying in the stroke direction of the sealing element, in particular a regeneration valve for a tank ventilation system in motor vehicles, with a magnetic armature and a return spring, the sealing element at least is partially guided by a flat spring, which is supported by a screen plate is surrounded.
In einer Reihe von Einsatzgebieten werden elektromagnetische Dosierventile eingesetzt, bei denen der Durchsatz in weiten Bereichen durch Variation des Puls-Pause-Verhältnisses der elektrischen Ansteuerung gesteuert werden kann. Hierzu wird der stirnseitig mit Dichtsitzelastomer versehene Magnetanker, der im Betrieb eine oszillierende Bewegung ausführt, mit variablen Zeitanteilen auf die Gegendichtfläche gepresst beziehungsweise je nach Höhe des gewünschten Durchflusses von der Gegendichtfläche abgehoben. Da diese Ventile im Betrieb sehr hohe Taktzahlen erreichen, muß die Lagerung des Magnetankers hohen Lebensdauerforderungen genügen. Die Ventile sollen beständig gegen aggressive Medien sein, in einem großen Temperaturbereich ihre Dosiergenauigkeit beibehalten, möglichst akustisch nicht wahrnehmbar sein und natürlich auch mit möglichst geringen Kosten hergestellt werden können. Überwiegend werden hier Magnetventile eingesetzt, die eine schnelle Bewegung des Dichtelements zulassen, d.h. deren Ansteuerungsfrequenz mindestens 10 Hz beträgt.Electromagnetic metering valves are used in a number of areas used in which the throughput in wide ranges by varying the Pulse-pause ratio of the electrical control can be controlled can. For this purpose, the magnet armature provided on the face with sealing pin elastomer, which performs an oscillating movement in operation, with variable Percentage of time pressed onto the counter-sealing surface or depending on the height of the desired flow rate from the counter-sealing surface. There these valves must reach very high cycle rates during operation, the storage of the magnet armature meet high durability requirements. The valves should be resistant to aggressive media in a wide temperature range maintain their dosing accuracy, if possible acoustically imperceptible be and of course also manufactured at the lowest possible cost can be. Solenoid valves are predominantly used here, one allow fast movement of the sealing element, i.e. their control frequency is at least 10 Hz.
In der DE 42 29 110 C 1 ist eine Tankentlüftungsanlage gezeigt, die für den Kraftstofftank vorgesehen ist und in die ein sogenanntes Regenerierventil eingesetzt ist. Dieses Regenerierventil besitzt ein Dichtelement für den Abschluss des Dichtsitzes, das von einer elektrisch angetriebenen Magnetspule betätigt wird. Diese Art von Regenerierventilen hat sich in der Praxis vielfach bewährt. Für die Ausbildung des Dichtsitzes können jedoch nur Elastomere verwendet werden, die mit dem Magnetanker durch Vulkanisation oder Verkleben fest und dauerhaft verbunden werden können. Da eine Reihe von Elastomeren wegen ihrer Zusammensetzung diese Forderung nicht erfüllen, wird nach Wegen gesucht, diese Elastomere wegen ihrer hohen Beständigkeit gegenüber aggressiven Medien und auch ihrer Dauerhaltbarkeit einsetzen zu können.In DE 42 29 110 C 1 a tank ventilation system is shown, for the Fuel tank is provided and in which a so-called regeneration valve is used. This regeneration valve has a sealing element for the Completion of the sealing seat by an electrically driven solenoid is operated. This type of regeneration valve has been put into practice proven many times. For the formation of the sealing seat, however, can only Elastomers are used with the magnet armature through vulcanization or bonding can be firmly and permanently connected. Since a number of elastomers because of their composition does not meet this requirement ways are sought, these elastomers because of their high Resistance to aggressive media and also their durability to be able to use.
US 4986246 und DE 19534396 zeigen andere Ausführungsformen einer Tankentlüftungsanlage.US 4986246 and DE 19534396 show other embodiments of a Tank ventilation system.
Der Erfindung liegt deshalb die Aufgaben zugrunde, eine Einsatzmöglichkeit für Elastomere bei Regenerierventilen zu finden, unabhängig von ihrer Zusammensetzung und ihrer Eigenschaft bezüglich der Verbindung zum Magnetanker. The invention is therefore based on the objects, an application for elastomers found in regeneration valves, regardless of their Composition and its property with regard to the connection to the Armature.
