Description
Stand der TechnikState of technology
Die Erfindung betrifft ein Ventilmodul zum Zuführen insbesondere gasförmiger Medien an eine Brennkraftmaschine nach der im Oberbegriff des Patentanspruches 1 näher definierten Art.The The invention relates to a valve module for supplying in particular gaseous media to an internal combustion engine according to the preamble of claim 1 closer defined type.
Aus
der
Im Bereich des Ventilsitzes umfasst das Ventil ein Dichtelement, welches an der Stirnseite des Ventilschließgliedes angeordnet ist und eine oder auch mehrere Dichtlippen aufweist. Das Dichtelement kann ringförmig ausgebildet und an der Stirnseite des Ventilschließgliedes in einer korrespondierenden Ringnut eingebettet sein.in the Area of the valve seat, the valve comprises a sealing element, which is arranged on the front side of the valve closure member and Has one or more sealing lips. The sealing element can annular formed and on the front side of the valve closure member be embedded in a corresponding annular groove.
Derartige bekannte Einspritzventile bzw. Einblasventile, welche zum Einsatz auch oder insbesondere bei gasförmigen Medien vorgesehen sind, sind bezüglich ihres Aufbaus und der Funktion im Wesentlichen von den für flüssige Medien gebräuchlichen Einspritzventilen abgeleitet, womit die spezifischen Anforderungen, die gasförmige Medien an Ventile stellen, gegebenenfalls nicht vollständig erfüllt werden. So sind an einen Gasverbrennungsmotor bzw. an eine Brennstoffzelle üblicherweise weitaus größere Fluidmengen zu fördern als an einen mit Flüssigbrennstoff betriebenen Verbrennungsmotor, weshalb der Ventilquerschnitt und der Ankerhub entsprechend zu dimensionieren sind. Zweckmäßigerweise werden bei gasförmigen Medien stromgeregelte Endstufen zur Öffnung der Ventile verwendet, welche sehr kurze Öffnungszeiten erlauben, jedoch das Ventilschließglied mit einer sehr hohen Geschwindigkeit auf den Ventilsitz auftreffen lassen.such known injection valves or injection valves, which are used also or especially gaseous Media are provided with respect Their construction and function are essentially that of liquid media common injection valves derived, bringing the specific requirements, the gaseous media to valves, may not be fully met. So are to one Gas combustion engine or to a fuel cell usually much larger amounts of fluid to promote as one with liquid fuel operated internal combustion engine, which is why the valve cross section and the armature stroke are to be dimensioned accordingly. Appropriately be at gaseous Media current-controlled output stages used to open the valves, which are very short opening times allow, however, the valve closure member with a very high Speed on the valve seat.
Problematisch ist dabei die hohe Belastung einer Dichteinrichtung zwischen dem Ventilschließglied und dem Ventilsitz, welche neben der Erhöhung der Dichtheit auch der Erhöhung der Lebensdauer des Ventils infolge der Verschleißreduktion an dem Ventilsitz sowie der Geräuschreduzierung dient. Da im Gegensatz zu flüssigkraftstoffbetriebenen Einspritzventilen, die durch die dem flüssigen Kraftstoff innewohnenden Schmiereigenschaften geschmiert werden, das Verschleißverhalten bei gasbetriebenen Ventilen zwischen dem Ventilschließglied und dem Ventilsitz deutlich ungünstiger ist, kommt der Gestaltung des Ventilschließglied-Ventilsitz-Bereiches und der darin vorgesehenen Dichteinrichtung eine besondere Bedeutung zu.Problematic is the high load of a sealing device between the Valve closure member and the valve seat, which in addition to increasing the tightness of the increase the life of the valve due to wear reduction at the valve seat as well as the noise reduction serves. As opposed to liquid fuel powered Injectors that are inherent in the liquid fuel Lubricating properties are lubricated, the wear behavior in gas-operated valves between the valve closing member and the valve seat significantly less favorable is the design of the valve closer valve seat area and the sealing device provided therein a special meaning to.
Es ist Aufgabe der vorliegenden Erfindung, ein Ventil zum Zuführen insbesondere gasförmiger Medien an eine Brennkraftmaschine der eingangs genannten Art zu schaffen, bei welchem die erforderliche Dichtheit über die gesamte Lebensdauer gewährleistet ist und welches durch einfache und kostengünstige Prozesse herstellbar ist.It Object of the present invention, a valve for supplying in particular gaseous media to provide an internal combustion engine of the type mentioned, in which the required tightness over the entire life guaranteed is and which can be produced by simple and inexpensive processes is.
Offenbarung der Erfindungepiphany the invention
Die erfindungsgemäße Lösung sieht vor, dass ein Ventilmodul zum Zuführen insbesondere gasförmiger Medien an eine Brennkraftmaschine, mit einer Ventilhülse, in der ein Ventilanker mit einem Ventilschließglied zur Einstellung eines Fluidstroms zwischen einer Zuströmseite und einer Abströmseite gegenüber einem fest in der Ventilhülse angeordneten Ventilsitzkörper mit einem Ventilsitz axial beweglich geführt ist, derart ausgestaltet ist, dass eine aus wenigstens zwei ringförmig ausgebildeten Dichtwülsten bestehende Dichteinrichtung vorgesehen ist, welche bezüglich der wenigstens einen Durchtrittsöffnung derart angeordnet ist, dass die wenigstens eine Durchtrittsöffnung in Schließstellung des Ventils zwischen den Dichtwülsten liegt.The sees solution according to the invention in that a valve module for supplying in particular gaseous media to an internal combustion engine, with a valve sleeve, in which a valve armature with a valve closure member for adjusting a fluid flow between an inflow side and a downstream side opposite a firmly in the valve sleeve arranged valve seat body is guided axially movable with a valve seat, designed in such a way is that a consisting of at least two annular sealing beads existing Sealing device is provided, which with respect to the at least one Through opening is arranged such that the at least one passage opening in closed position the valve between the sealing beads lies.
