Description
Die vorliegende Erfindung geht von einem Ventil zum Steuern eines Fluids, insbesondere zum Steuern eines Gases, gemäß der im Oberbegriff des Patentanspruchs 1 näher definierten Art aus.The present invention relates to a valve for controlling a fluid, in particular for controlling a gas, according to the preamble of the claim 1 closer defined type.
Ein derartiges Ventil ist aus der Praxis bekannt und beispielsweise als Gassteuerventil bei einer Brennstoffzelle eines Kraftfahrzeugs oder auch bei einem Gasmotor einsetzbar.One Such valve is known in practice and, for example as a gas control valve in a fuel cell of a motor vehicle or can also be used in a gas engine.
Ein bekanntes Ventil der einleitend genannten Art umfasst ein Ventilgehäuse und eine elektromagnetische Betätigungseinheit, die zur Betätigung eines Magnetankers dient. Der Magnetanker ist in dem Ventilgehäuse, insbesondere in einer Hülse des Ventilgehäuses, an seiner Mantelfläche axial verschiebbar geführt und in einem stirnseitigen Bereich als Ventilschließglied ausgebildet, das mit einem Ventilsitz zusammenwirkt. In Abhängigkeit von der Stellung des Magnetankers ist ein Fluidstrom von einer Zuströmseite zu einer Abströmseite des Ventils steuerbar.One known valve of the aforementioned type comprises a valve housing and an electromagnetic actuator, to operate a Magnet armature serves. The armature is in the valve housing, in particular in a sleeve the valve housing, on its lateral surface guided axially displaceable and formed in a frontal region as a valve closure member, which cooperates with a valve seat. Depending on the position of the Magnetic armature is a fluid flow from an inlet side to a downstream side of the Valve controllable.
Das Ventilschließglied weist in seinem Stirnbereich ein in der Regel aus einem Elastomer gebildetes Dichtelement auf, das zur Erzielung einer hinreichenden Gasdichtheit in Schließstellung des Ventils mit einem Ventilsitz zusammenwirkt und hierzu zur Abströmseite des Ventils führende Zumessbohrungen in einer Ventilsitzplatte abdichtet. Das eingesetzte Elastomer hat ein derartiges Wärmeausdehnungsverhalten, dass sich der Ventilhub bei zunehmender Temperatur verringert, und zwar um etwa 10 μm pro 100°K. Dies liegt darin begründet, dass Bauteile, die sich parallel zur Achse des Magnetankers erstrecken und die insbesondere aus Stahl gebildet sind, einen deutlich geringeren Wärmeausdehnungskoeffizienten als das Elastomer aufweisen. Der sich ändernde Ventilhub führt zu einer Drift der statischen und auch der dynamischen Durchflussmenge an Gas, was nicht wünschenswert ist.The Valve closure member has in his forehead a usually made of an elastomer formed sealing element, which is to achieve a sufficient Gas tightness in the closed position the valve cooperates with a valve seat and to the downstream side of the Valve leading Seals drilled in a valve seat plate seals. The used Elastomer has such a thermal expansion behavior, that the valve lift decreases with increasing temperature, and although by about 10 microns per 100 ° K. This is due to that components that extend parallel to the axis of the armature and which are formed in particular of steel, a much lower CTE as the elastomer. The changing valve lift leads to a Drift of static and dynamic flow of gas, which is not desirable is.
Der Erfindung liegt die Aufgabe zugrunde, ein Ventil zum Steuern eines Fluids zu schaffen, das gegenüber dem oben beschriebenen Stand der Technik mit einer verringerten temperaturbedingten Hubänderung behaftet ist.Of the Invention is based on the object, a valve for controlling a Fluids create that opposite the above-described prior art with a reduced temperature-related stroke change is afflicted.
Vorteile der ErfindungAdvantages of invention
Das erfindungsgemäße Ventil zum Steuern eines Fluids, insbesondere zum Steuern eines Gases, mit den Merkmalen nach dem Oberbegriff des Patentanspruchs 1 und einem Ventilschließglied, das als Dichtplatte ausgeführt ist, die axial verschiebbar in einem Innenraum des Magnetankers geführt ist und die mittels einer Rückstellfeder in Schließrichtung vorgespannt ist, hat den Vorteil, dass durch die so herbeigeführte getrennte Ausführung des Ventilschließglieds und des Magnetankers eine Vergleichmäßigung des Ventilhubs über einen großen Temperaturbereich erreicht werden kann, was gegenüber dem Stand der Technik zu einer besseren Ventillinearität, einer reduzierten Drift der statischen Durchflussmenge und zu einer reduzierten Drift der dynamischen Durchflussmenge führt.The inventive valve for controlling a fluid, in particular for controlling a gas, with the features according to the preamble of patent claim 1 and a valve closure member, this is done as a sealing plate is, which is axially displaceable in an interior of the armature guided is and by means of a return spring in the closing direction is biased, has the advantage that by the thus induced separate execution the valve closure member and the magnet armature a homogenization of the valve lift over a huge Temperature range can be achieved, which is opposite to the State of the art for a better valve linearity, a reduced drift of static flow and at a reduced rate Drift of the dynamic flow rate leads.
Des Weiteren liegt bei dem erfindungsgemäß ausgebildeten Ventil durch die Entkopplung der Magnetankermasse von dem Ventilschließglied im Vergleich zu dem Stand der Technik eine Reduzierung des Anschlagimpulses vor, was wiederum zu einem geringeren Verschleiß im Bereich des Ventilsitzes und zu einer geringeren Geräuschentwicklung führt.Of Further is in the inventively designed valve through the decoupling of the magnetic armature mass of the valve closure member in comparison to the prior art, a reduction of the stop pulse before which in turn leads to less wear in the region of the valve seat and leads to a lower noise level.
Das Ventil nach der Erfindung ist insbesondere zur Massenstromregelung von Gasen wie Wasserstoff und Erdgas geeignet und kann beispielsweise in Verbindung mit einer Brennstoffzelle oder auch bei einem Gasmotor eines Kraftfahrzeugs eingesetzt werden. In letzterem Anwendungsfall mündet das Ventil insbesondere in ein Saugrohr, das zu einem Zylinder des Gasmotors führt.The Valve according to the invention is in particular for mass flow control suitable for gases such as hydrogen and natural gas and can, for example in connection with a fuel cell or even with a gas engine a motor vehicle are used. In the latter application ends In particular, the valve in a suction pipe, which is a cylinder of the Gas engine leads.
Bei einer speziellen Ausführungsform des Ventils nach der Erfindung weist die Dichtplatte zwei Ringflächen auf, von denen eine mit dem Dichtelement zur Anlage an dem Ventilsitz versehen ist und die andere mit einem Hubkompensationselement versehen ist, das mit einem Ringbund des Magnetankers zusammenwirkt. In diesem Fall weist die insbesondere ringförmige Dichtplatte also einen Absatz auf, so dass zwei Ringflächen ausgebildet sind. Das Hubkompensationselement, das mit dem Ringbund des Magnetankers zusammenwirkt, hat zweckmäßigerweise ebenfalls einen größeren Wärmeausdehnungskoeffizienten als der Werkstoff des Ventilgehäuses.at a special embodiment of the valve according to the invention, the sealing plate has two annular surfaces, one of which with the sealing element for engagement with the valve seat is provided and the other provided with a Hubkompensationselement is, which cooperates with a collar of the magnet armature. In this Case, the particular annular sealing plate so a Paragraph on, leaving two ring surfaces are formed. The stroke compensation element connected to the collar of the Magnet armature cooperates, has expediently also one larger thermal expansion coefficient as the material of the valve housing.
Um temperaturbedingte Volumenänderungen des Dichtelementes besonders präzise ausgleichen zu können, ist das Hubkompensationselement vorzugsweise aus dem gleichen Werkstoff wie das Dichtelement, insbesondere aus einem Elastomer gebildet. Der Werkstoff des Hubkompensationselementes und der Werkstoff des Dichtelementes haben damit den gleichen Wärmeausdehnungskoeffizienten.Around temperature-related volume changes the sealing element particularly precise to be able to balance the Hubkompensationselement is preferably made of the same material as the sealing element, in particular made of an elastomer. The material of the Hubkompensationselementes and the material of Sealing element thus have the same thermal expansion coefficient.
Bei gleichen Wärmeausdehnungskoeffizienten der für das Dichtelement und das Hubkompensationselement eingesetzten Werkstoffe ist es zweckmäßig, wenn das Hubkompensationselement die gleiche Dicke wie das Dichtelement hat. Dann ist sichergestellt, dass eine Volumenänderung des Dichtelementes durch eine Volumenänderung des Hubkompensationselementes so kompensiert wird, dass der Ventilhub über einen großen Temperaturbereich konstant bleibt.With the same coefficients of thermal expansion of the materials used for the sealing element and the Hubkompensationselement it is expedient if the Hubkompensationselement the same thickness as the sealing element has. Then it is ensured that a change in volume of the sealing element is compensated by a change in volume of Hubkompensationselementes so that the valve lift over a wide temperature range remains constant.
Bei einer alternativen Ausführungsform des Ventils nach der Erfindung ist die Dichtplatte mit einer ebenen Wirkfläche ausgebildet, das Dichtelement einstückig mit einem Hubkompensationselement ausgebildet, das sich an einem Ringbund des Magnetankers abstützt, und taucht eine an dem Ventilsitz ausgebildete Dichtfläche zumindest in Schließstellung des Magnetankers in dessen Innenraum ein. Diese Ausführungsform zeichnet sich durch ein einfaches Herstellen des Ventilschließgliedes bzw. der Dichtplatte aus.at an alternative embodiment the valve according to the invention is the sealing plate with a flat effective area formed, the sealing element formed integrally with a Hubkompensationselement, which is supported on a collar of the magnet armature, and dives on the Valve seat trained sealing surface at least in the closed position of the armature in the interior of a. This embodiment is characterized by a simple manufacture of the valve closure member or the sealing plate off.
