Description

Die Erfindung betrifft eine Entlüftungseinrichtung für einen Kraftstoffbehälter eines Kraftfahrzeugs nach dem Oberbegriff des Hauptanspruchs.The The invention relates to a venting device for one Fuel tank of a motor vehicle according to the preamble of the main claim.

Es ist bereits bekannt, einen Kraftfahrzeugkraftstofftank mit einer Entlüftungseinrichtung zu versehen, die aus einer großdurchmeßrigen Betankungsentlüftungsleitung und eine kleindurchmeßrigen Betriebsentlüftungsleitung besteht. Dabei sind Betankungs- und Betriebsentlüftungsleitung über ein gemeinsames Mehrwegventil zu einem Kraftstoffdampfauffangbehälter geführt. Das Mehrwegventil wird durch Einführen einer Zapfpistole in den Einfüllstutzen von einer Betriebsstellung, in welcher die Betriebsentlüftungsleitung geöffnet und die Betankungsentlüftungsleitung geschlossen ist, in eine Betankungsstellung, in welcher die Betankungsentlüftungsleitung geöffnet und die Betriebsentlüftungsleitung geschlossen ist, umgeschaltet.It is already known, a motor vehicle fuel tank with a vent provided from a large-capacity refueling vent line and a small diameter Operating vent line consists. In this case, refueling and operating vent line are via a common Multi-way valve led to a fuel vapor recovery tank. The multi-way valve is by introducing a fuel nozzle in the filler neck from an operating position in which the operating vent line open and the refueling vent line is closed, in a refueling position, in which the refueling vent line open and the service vent line closed, switched.

Die EP 0 882 617 A2 beschreibt unter anderem eine solche Entlüftungseinrichtung, bei der das Mehnnregventil in der Verbindung zwischen Kraftstofftank und Aktivkohlebehälter eingebaut ist.The EP 0 882 617 A2 describes inter alia such a venting device, in which the Mehnnregventil is installed in the connection between the fuel tank and the activated carbon container.

Diese Entlüftungseinrichtung hat den Nachteil, dass das Mehrwegventil auf der sogenannten nassen Seite der Entlüftungseinrichtung liegt. Es muss sorgfältigst abgedichtet werden um niedrige Permeation und geringe Leckage zu gewährleisten. Dasselbe gilt für die Betätigungseinrichtung des Mehrwegventils über die Zapfpistole. Die Entlüftungseinrichtung besteht daher aus vielen Teilen und ist nicht einfach aufgebaut.These vent has the disadvantage that the multi-way valve on the so-called wet Side of the venting device lies. It has to be done carefully be sealed to low permeation and low leakage too guarantee. The same thing applies to the actuating device of the returnable valve over the fuel nozzle. The venting device therefore consists of many parts and is not simple.

Deshalb ist es Aufgabe der Erfindung, eine Entlüftungseinrichtung bereitzustellen, die bei gleicher Wirkung einfacher aufgebaut und daher preiswerter herzustellen ist.Therefore It is an object of the invention to provide a venting device, the simpler structure with the same effect and therefore cheaper is to produce.

Die Aufgabe wird mit den Merkmalen des Anspruchs 1 gelöst. Weitere Ausgestaltungen der Erfindung ergeben sich aus den Unteransprüchen.The The object is achieved with the features of claim 1. Further Embodiments of the invention will become apparent from the dependent claims.

Nach der Erfindung ist eine Entlüftungseinrichtung für einen Kraftstoffbehälter eines Kraftfahrzeugs mit einer in den freien Endabschnitt des Einfüllstutzens mündenden Betankungsentlüftungsleitung und einer über einen Kraftstoffdampfauffangbehälter geführten Betriebsentlüftungsleitung und mit einer Ventileinrichtung, die wenigstens die Betriebsentlüftungsleitung geschlossen hält, wenn die Betankungsentlüftungsleitung geöffnet ist, dadurch gekennzeichnet, dass die Ventileinrichtung an der Frischluftseite des Kraftstoffdampfauffangbehälters angeschlossen ist und dort die zum Kraftstoffdampfauffangbehälter 5 führende Betriebsentlüftungsleitung 6 geschlossen hält, wenn die Betankungsentlüftungsleitung geöffnet ist.According to the invention, a venting device for a fuel tank of a motor vehicle is provided with a refueling vent line opening into the free end section of the filler neck and an operating vent line guided via a fuel vapor collecting container and with valve means keeping at least the operating vent line closed when the refueling vent line is open the valve device is connected to the fresh air side of the fuel vapor collecting container and there to the fuel vapor collecting container 5 leading operating ventilation line 6 keeps closed when the refueling vent line is open.

Das hat den Vorteil, dass die Ventileinrichtung auf der sogenannten trockenen Seite der Entlüftungseinrichtung liegt. Sie kann dadurch einfach aufgebaut sein, da keine Maßnahmen zur Verhinderung von Permeation oder Leckage getätigt werden müssen.The has the advantage that the valve device on the so-called dry side of the venting device lies. It can therefore be simple, because no action must be made to prevent permeation or leakage.

Weitere vorteilhafte Ausführungen der Erfindung sehen vor, dass die Ventileinrichtung durch Öffnen des Tankdeckels oder der Tankdeckelverkleidung oder durch Einführen der Tank-Zapfpistole in den Einfüllstutzen zur Sperrung der Betriebsentlüftungsleitung betätigt wird. Dabei kann die Betätigung mechanisch erfolgen, insbesondere über einen Bowdenzug durch Öffnen des Tankdeckels oder der Tankdeckelverkleidung oder durch Einführen der Tank-Zapfpistole in den Einfüllstutzen.Further advantageous embodiments of the invention provide that the valve device by opening the Tank cap or the fuel cap cover or by inserting the Tank fuel nozzle in the filler neck to block the operating vent line actuated becomes. The operation can be mechanical take place, in particular via a Bowden cable by opening the fuel filler cap or fuel cap cover or by inserting the fuel nozzle in the filler neck.

Vorteilhafterweise kann die Ventileinrichtung dadurch an irgendeiner günstigen Stelle platziert werden. Die Bowdenzugbetätigung ermöglicht dies.advantageously, The valve device can thereby at any convenient Place to be placed. The Bowden cable operation allows this.

Ein bevorzugtes Ausführungsbeispiel der Erfindung beschreibt die nachfolgende Beschreibung mit der zugehörigen Zeichnung. Die einzige Figur zeigt eine schematische Skizze einer erfindungsgemäßen Entlüftungseinrichtung für einen Kraftstoffbehälter.One preferred embodiment The invention describes the following description with the accompanying drawings. The single FIGURE shows a schematic sketch of a venting device according to the invention for one Fuel tank.

Ein Kraftstoffbehälter 1 eines nicht gezeichneten Kraftfahrzeugs ist mit einer in den freien Endabschnitt 2 des Einfüllstutzens 3 mündenden Betankungsentlüftungsleitung 4 bestückt. Außerdem ist der Kraftstoffbehälter 1 mit einer über einen Kraftstoffdampfauffangbehälter 5 geführten Betriebsentlüftungsleitung 6 und einer Ventileinrichtung 7 bestückt. Diese hält wenigstens die Betriebsentlüftungsleitung 6 geschlossen, wenn die Betankungsentlüftungsleitung 4 geöffnet ist.A fuel tank 1 a non-illustrated motor vehicle is with a in the free end portion 2 of the filler neck 3 opening refueling vent line 4 stocked. In addition, the fuel tank 1 with a via a fuel vapor collecting container 5 guided operating ventilation line 6 and a valve device 7 stocked. This holds at least the operating vent line 6 closed when the refueling vent line 4 is open.

Die Ventileinrichtung 7 ist an der Frischluftseite 8 des Kraftstoffdampfauffangbehälters 5 angeschlossen und hält dort die zum Kraftstoffdampfauffangbehälter 5 führende Betriebsentlüftungsleitung 6 geschlossen, wenn die Betankungsentlüftungsleitung 4 geöffnet ist.The valve device 7 is on the fresh air side 8th of the fuel vapor collecting container 5 connected and holds there to the fuel vapor collecting container 5 leading operating ventilation line 6 closed when the refueling vent line 4 is open.

Dabei wird die Ventileinrichtung 7 durch Öffnen einer Tankdeckelverkleidung 10 zur Sperrung der zum Kraftstoffdampfauffangbehälter 5 hin führenden Betriebsentlüftungsleitung 6 betätigt. Genauso ist es möglich, die Ventileinrichtung 7 durch Öffnen eines nicht gezeichneten Tankdeckels oder durch Einführen einer nicht gezeichneten Tank-Zapfpistole in den Einfüllstutzen zu betätigen. Dazu ist die Ventileinrichtung 7 über einen Bowdenzug 11 mit der Tankdeckelverkleidung 10 verbunden.In this case, the valve device 7 by opening a gas cap cover 10 for blocking the fuel vapor collecting container 5 leading operational ventilation line 6 actuated. It is equally possible to use the valve device 7 by opening a not shown tank cap or by inserting a non-illustrated tank fuel nozzle to press into the filler neck. This is the valve device 7 over a Bowden cable 11 with the fuel tank cover 10 connected.
