Abstract
Description
Die Erfindung geht aus von einem Zumeßventil für gefrierfähige Medien wie Wasser, Harnstoffwasserlösung und Alkohol-Wasserlösungen nach der Gattung des Hauptanspruchs.The The invention is based on a metering valve for freezable media such as water, urea water solution and Alcohol-water solutions according to the preamble of the main claim.
Bei Brennstoffzellenfahrzeugen, welche mit Wasserstoff oder mit einem Reformersystem betrieben werden, müssen die Brennstoffzellenmembranen mittels Dosierung von deionisiertem Wasser in den Luftpfad befeuchtet werden bzw. das Wasser für den Reformierungsprozeß muß zugemessen werden. Dies wird beim gegenwärtigen Stand der Technik aufgrund der Anforderungen für die Gefrierfestigkeit solcher Dosierventile mittels nicht kraftfahrzeugtauglicher Funktionsmuster oder über sehr kostenintensive und daher nicht serienreife Laborventile realisiert. Auch sind diese Dosierventile nur bedingt gefrierfest mit der Folge von Beschädigungen durch das gefrierende Medium und dadurch bedingte Ausfälle des Dosierventils oder des Feindosierverhaltens.at Fuel cell vehicles, which with hydrogen or with a Be operated reformer system, the fuel cell membranes moistened by dosing of deionized water in the air path or the water for the Reforming process must be measured become. This will be at the present State of the art due to the requirements for the freezing resistance of such Dosing valves by means of non-motor vehicle functional function patterns or over very cost-intensive and therefore not series-ready laboratory valves realized. Also, these metering valves are only partially freezing with the result of damage by the freezing medium and consequent failures of the Metering valve or the Feindosierverhaltens.

Vorteile der ErfindungAdvantages of invention
Das erfindungsgemäße Zumeßventil mit den kennzeichnenden Merkmalen des Hauptanspruchs hat demgegenüber den Vorteil, daß im Bereich der Ventilhülse und/oder einer das Zumeßventil verlängernden Verlängerungshülse zumindest eine Ausnehmung ausgebildet ist, in welcher zumindest eine komprimierbare Dichtung angeordnet ist. Die komprimierbare Dichtung kann der Ausdehnung der gefrierenden Flüssigkeit ausweichen.The metering valve according to the invention with the characterizing features of the main claim has the Advantage that in Area of the valve sleeve and / or a metering valve lengthening Extension sleeve at least a recess is formed, in which at least one compressible Seal is arranged. The compressible seal can expand the freezing liquid dodge.
Durch die in den Unteransprüchen aufgeführten Maßnahmen sind vorteilhafte Weiterentwicklungen des im Hauptanspruch angegebenen Zumeßventils möglich.By in the subclaims listed activities are advantageous developments of the specified in the main claim metering valve possible.
Vorteilhafterweise ist die zumindest eine Dichtung in Form eines O-Rings ausgeführt, welcher ein offenes Ringprofil oder ein geschlossenes Profil aufweisen kann. Die Dichtung ist dabei beispielsweise aus Moosgummi oder einem Elastomer hergestellt.advantageously, is the at least one seal executed in the form of an O-ring, which a may have open ring profile or a closed profile. The seal is for example made of sponge rubber or an elastomer produced.
Von Vorteil ist außerdem, daß die Ausnehmung einen entsprechenden eckigen oder rundlichen Querschnitt aufweisen kann.From Another advantage is that the Recess a corresponding square or round cross-section can have.
Die Ausnehmung dient als Ausgleichsvolumen für die Ausdehnung der das Zumeßventil durchströmenden Flüssigkeit in der Gefrierphase und als Aufnahme für die Dichtung.The Recess serves as a compensating volume for the expansion of the metering valve flowing through liquid in the freezing phase and as a receptacle for the seal.
