Description
Stand der TechnikState of the art
Die vorliegende Erfindung betrifft ein Proportionalventil zum Steuern eines gasförmigen Mediums, insbesondere Wasserstoff und insbesondere zur Anwendung in Fahrzeugen mit Brennstoffzellenantrieb.The present invention relates to a proportional valve for controlling a gaseous medium, in particular hydrogen and in particular for use in vehicles with fuel cell drive.
Im Fahrzeugbereich spielen neben flüssigen Kraftstoffen in Zukunft auch gasförmige Kraftstoffe eine zunehmende Rolle. Insbesondere bei Fahrzeugen mit Brennstoffzellenantrieb müssen Wasserstoffgasströme gesteuert werden. Die Gasströme werden hierbei nicht mehr diskontinuierlich wie bei der Einspritzung von flüssigem Kraftstoff gesteuert, sondern es werden vorzugsweise Proportionalventile eingesetzt, die in Abhängigkeit von einer gewünschten Antriebsleistung einen Öffnungsquerschnitt des Ventils anpassen. In the vehicle sector, in addition to liquid fuels, gaseous fuels will also play an increasing role in the future. In particular, in vehicles with fuel cell drive hydrogen gas flows must be controlled. The gas flows are no longer controlled discontinuously as in the injection of liquid fuel, but it is preferably proportional valves used, which adjust an opening cross-section of the valve depending on a desired drive power.
Aufgrund der kleinen Molekülgröße von gasförmigem Wasserstoff sind hohe Anforderungen hinsichtlich einer Dichtheit des Proportionalventils zu erfüllen. Hierbei können schon minimale Schrägstellungen eines Schließelements zu unerwünschten Leckagen führen. Aus der
Offenbarung der ErfindungDisclosure of the invention
Das erfindungsgemäße Proportionalventil zum Steuern eines gasförmigen Mediums mit den Merkmalen des Anspruchs 1 weist demgegenüber den Vorteil auf, dass eine weiter verbesserte Dichtheit am Ventilsitz gewährleistet ist. Insbesondere kann eine erhöhte Dichtheit des Proportionalventils in einem Temperaturbereich von –40° bis 0°C, in welchem das Dichtelement temperaturbedingt üblicherweise wenig elastisch ist, erreicht werden. Die verbesserte Dichtheit wird insbesondere durch ein verbessertes Anliegen des Dichtelements an einem Ventilsitz erreicht. Hierzu ist erfindungsgemäß vorgesehen, dass das elastische Dichtelement, welches am Ventilsitz abdichtet, eine Ausnehmung aufweist. Die Ausnehmung definiert am Dichtelement einen Innenwandbereich, welcher im geschlossenen Zustand des Proportionalventils mit Druck aus einem Druckbereich des Proportionalventils beaufschlagt ist. Somit kann erfindungsgemäß zusätzlich zu dem auf das Dichtelement wirkenden Schließdruck, beispielsweise durch eine Schließfeder, ein Schließdruck durch den Druck des zu steuernden, gasförmigen Mediums bereitgestellt werden. Dadurch ist insbesondere eine effektive Abdichtung von gasförmigem Wasserstoff, welcher eine sehr kleine Molekülgröße aufweist, möglich. Das Ventil wird vorzugsweise zur Zuführung von Wasserstoff zu einer Brennstoffzelle verwendet.The proportional valve according to the invention for controlling a gaseous medium with the features of
Die Unteransprüche zeigen bevorzugte Weiterbildungen der Erfindung.The dependent claims show preferred developments of the invention.
Vorzugsweise ist die Ausnehmung im Dichtelement eine Sackloch-Ausnehmung. Hierdurch kann auf einfache Weise am Dichtelement ein Innenwandbereich bereitgestellt werden, auf welchen ein Gasdruck ausgeübt werden kann.Preferably, the recess in the sealing element is a blind hole recess. As a result, an inner wall region, on which a gas pressure can be exerted, can be provided in a simple manner on the sealing element.
Alternativ ist die Ausnehmung im Dichtelement eine Durchgangs-Ausnehmung. Vorzugsweise ist das Dichtelement ringförmig gebildet und weist bevorzugt mittig die Durchgangs-Ausnehmung auf, welche koaxial zu einer Mittelachse des Proportionalventils ausgerichtet ist. Weiter bevorzugt weist hierbei zusätzlich noch das Schließelement eine Sackloch-Ausnehmung auf, wodurch die Durchgangs-Ausnehmung im Dichtelement weiter in das Schließelement geführt wird. Alternatively, the recess in the sealing element is a passage recess. Preferably, the sealing element is annular and preferably has in the middle the through-hole, which is aligned coaxially with a central axis of the proportional valve. In this case, the closing element furthermore preferably has a blind-hole recess, as a result of which the passage recess in the sealing element is guided further into the closing element.
Für einen besonders einfachen Aufbau weist das Proportionalventil als Durchlassöffnung eine einzige zentrale Durchlassöffnung auf. Besonders bevorzugt ist hierbei die Ausnehmung im Dichtelement koaxial zur Durchlassöffnung vorgesehen.For a particularly simple construction, the proportional valve has as passage opening a single central passage opening. In this case, the recess in the sealing element is particularly preferably provided coaxially with the passage opening.
Gemäß einer weiteren bevorzugten Ausgestaltung der Erfindung weist der Ventilsitz eine umlaufend vorstehende Dichtlippe auf, die im Schnitt bogenförmig ausgebildet ist. Hierdurch ergibt sich am Ventilsitz eine Sitzfläche, an die sich das Dichtelement besonders gut anlegen kann und im geschlossenen Zustand eine möglichst große Kontaktfläche zwischen dem Dichtelement und dem Ventilsitz realisiert werden kann. Vorzugsweise beträgt dabei ein Radius der umlaufenden Dichtlippe etwa 0,1 mm. Ferner kann hierdurch eine besonders gute unterstützende Wirkung des Gasdrucks bei der Abdichtung erreicht werden.According to a further preferred embodiment of the invention, the valve seat on a circumferentially projecting sealing lip, which is arc-shaped in section. This results in the valve seat, a seat to which the sealing element can invest particularly well and when closed the largest possible contact surface between the sealing element and the valve seat can be realized. Preferably, a radius of the circumferential sealing lip is about 0.1 mm. Furthermore, a particularly good supporting effect of the gas pressure in the sealing can be achieved thereby.
Alternativ kann der Ventilsitz auch einen abgerundeten Übergang zur Durchlassöffnung aufweisen.Alternatively, the valve seat may also have a rounded transition to the passage opening.
Vorzugsweise liegt ein Verhältnis eines Innendurchmessers der Ausnehmung des Dichtelements zu einem Durchmesser der zentralen Durchgangsöffnung in einem Bereich von 0,40 bis 0,80 und beträgt besonders bevorzugt ungefähr 0,60. Preferably, a ratio of an inner diameter of the recess of the sealing member to a diameter of the central through hole is in a range of 0.40 to 0.80, and more preferably about 0.60.
Weiter bevorzugt beträgt im unbelasteten Zustand ein Verhältnis einer Tiefe der Ausnehmung am Dichtelement zu einer Dicke des Dichtelements jeweils in Axialrichtung des Proportionalventils mindestens 2:5, vorzugsweise 4:5. More preferably, in the unloaded state, a ratio of a depth of the recess on the sealing element to a thickness of the sealing element in each case in the axial direction of the proportional valve at least 2: 5, preferably 4: 5.
Die Erfindung betrifft ferner eine Brennstoffzellenanordnung mit einer Brennstoffzelle und mit einem erfindungsgemäßen Proportionalventil zur Steuerung von gasförmigem Wasserstoff.The invention further relates to a fuel cell arrangement with a fuel cell and with a proportional valve according to the invention for controlling gaseous hydrogen.

Somit unterstützt erfindungsgemäß bei geschlossenem Proportionalventil der Druck des gasförmigen Mediums die Abdichtung am Ventilsitz
Weiterhin wird der erfindungsgemäße Effekt mit zunehmendem Druck des gasförmigen Mediums verstärkt, da mit zunehmendem Druck aufgrund der erhöhten Gasdichte auch die Anforderungen an die Dichteigenschaften des Proportionalventils zunehmen. Daher ist der erfindungsgemäße Effekt besonders vorteilhaft. Furthermore, the effect according to the invention is enhanced with increasing pressure of the gaseous medium, since with increasing pressure due to the increased gas density, the requirements for the sealing properties of the proportional valve also increase. Therefore, the effect of the invention is particularly advantageous.
