Description
Die Erfindung betrifft einen Kraftstoffbehälter für ein Kraftfahrzeug mit einer eine Betankungsentlüftung und eine Betriebsentlüftung aufweisenden Entlüftungseinrichtung, mit einer Entlüftungsleitung der Betankungsentlüftung und mit einer bis in vorgesehene Bereiche des Kraftstoffbehälters geführten Entlüftungsleitung der Betriebsentlüftung, wobei die Betankungsentlüftung und die Betriebsentlüftung über eine Leitung mit einem Aktivkohlefilter verbunden sind.The The invention relates to a fuel tank for a motor vehicle with a a refueling vent and an operating vent having venting device, with a vent line of the refueling vent and with a guided into intended areas of the fuel tank vent line the operating ventilation, the refueling vent and the operating ventilation via a Line are connected to an activated carbon filter.
Solche Kraftstoffbehälter werden in heutigen Kraftfahrzeugen häufig eingesetzt und sind aus der Praxis bekannt. Die Betriebsentlüftung ermöglicht ein Entweichen von Kraftstoffdämpfen im Betrieb des Kraftfahrzeuges und ein Nachströmen von Luft bei einem Verbrauch des Kraftstoffs. Die Betankungsentlüftung leitet von dem eingefüllten Kraftstoff verdrängte Luft aus dem Kraftstoffbehälter durch den Aktivkohlefilter. Der Aktivkohlefilter hat eine Verbindung mit der Umgebung zur Ermöglichung eines Druckausgleichs. Bei dem bekannten Kraftstoffbehälter werden die Betriebsentlüftung und die Betankungsentlüftung aufwändig an dem Kraftstoffbehälter montiert.Such Fuel tank are commonly used in today's vehicles and are out known practice. The operating vent allows escape of fuel vapors in the Operation of the motor vehicle and a backflow of air at a consumption of the fuel. The refueling vent leads from the filled fuel displaced Air from the fuel tank through the activated carbon filter. The activated carbon filter has a connection with the environment to make it possible a pressure equalization. In the known fuel tank the operating ventilation and the refueling vent costly mounted on the fuel tank.
Der Erfindung liegt das Problem zugrunde, einen Kraftstoffbehälter mit einer Entlüftungseinrichtung so zu gestalten, dass der Kraftstoffbehälter mit der Entlüftungseinrichtung besonders einfach zu montieren und zu fertigen ist.Of the Invention is based on the problem, a fuel tank with a venting device to be designed so that the fuel tank with the venting device particularly easy to assemble and manufacture.
Dieses Problem wird erfindungsgemäß dadurch gelöst, dass die Betankungsentlüftung und die Betriebsentlüftung einen gemeinsamen Behälter aufweisen und dass der Behälter jeweils eine Kammer für die Betankungsentlüftung und die Betriebsentlüftung hat.This Problem is inventively characterized solved, that the refueling vent and the operating vent a common container have and that the container one chamber each for the refueling vent and the operating vent Has.
Durch diese Gestaltung lassen sich die wesentlichen Bauteile der Betriebsentlüftung und der Betankungsentlüftung zu einer baulichen Einheit vormontieren und in den erfindungsgemäßen Kraftstoffbehälter einsetzen. Der gemeinsame, die Kammern aufweisende Behälter lässt sich zudem besonders einfach fertigen. Die Trennung des Behälters in die beiden Kammern ermöglicht eine zuverlässige Führung der Kraftstoffdämpfe über den Aktivkohlefilter. Die Kammern sind vorzugsweise vollständig voneinander getrennt.By This design can be the essential components of the operation ventilation and the refueling vent preassembled to a structural unit and insert into the fuel tank according to the invention. The common container having the chambers is also particularly easy finished. The separation of the container in the two chambers allowed a reliable one guide the fuel vapors over the Activated carbon filter. The chambers are preferably completely separate from each other separated.
Der bauliche Aufwand für die Entlüftungseinrichtung lässt sich besonders gering halten, wenn die Betankungsentlüftung und die Betriebsentlüftung jeweils ein Ventil aufweisen und wenn die Ventile an der zu dem Aktivkohlefilter führenden Leitung angeschlossen sind. Die Ventile verhindern hierdurch, dass flüssiger Kraftstoff bis zu dem Aktivkohlefilter vordringt und diesen schädigt.Of the constructional effort for the venting device let yourself keep it low if the refueling vent and the exhaust vent respectively have a valve and if the valves on the to the activated carbon filter leading Line are connected. The valves thereby prevent that liquid Fuel penetrates to the activated carbon filter and this damages.
Die Steuerung der Betankungsentlüftung gestaltet sich gemäß einer anderen vorteilhaften Weiterbildung der Erfindung konstruktiv besonders einfach, wenn zumindest eines der Ventile als Schwimmerventil ausgebildet ist.The Control of refueling ventilation designed according to a other advantageous development of the invention constructive particularly easy if at least one of the valves designed as a float valve is.
Die Steuerung der Betriebsentlüftung gestaltet sich gemäß einer anderen vorteilhaften Weiterbildung der Erfindung konstruktiv besonders einfach, wenn das Ventil der Betriebsentlüftung als die zu dem Aktivkohlefilter führende Leitung unterhalb eines vorgesehenen Drucks im Kraftstoffbehälter verschließendes Druckhalteventil ausgebildet ist.The Control of the operating ventilation designed according to a other advantageous development of the invention constructive particularly easy, if the valve of the operating vent than that to the activated carbon filter premier Line below a pressure provided in the fuel tank closing pressure retaining valve is trained.
Eine Entleerung der Kammern der Entlüftungseinrichtung gestaltet sich besonders einfach, wenn die Betankungsentlüftung und die Betriebsentlüftung jeweils eine Saugstrahlpumpe aufweisen und wenn Ansaugöffnungen der Saugstrahlpumpen mit jeweils einer Kammer der Betankungsentlüftung und der Betriebsentlüftung verbunden sind. Vorzugsweise werden die Saugstrahlpumpen von einer innerhalb des Kraftstoffbehälters an geordneten Kraftstoffpumpe mit Kraftstoff als Treibmittel versorgt. Durch diese Gestaltung sind die Kammern der Entlüftungseinrichtung im Betrieb des Kraftfahrzeuges ständig leer. Daher vermögen die als Schwimmerventile ausgebildeten Ventile die Leitungen zu dem Aktivkohlefilter auch bei einem Überschlag des Kraftfahrzeuges zu verschließen. Die Ventile der Entlüftungseinrichtung dienen daher auch als so genannte Roll-Over-Ventile.A Emptying the chambers of the venting device turns out to be particularly easy when the refueling vent and the operating ventilation each have a suction jet pump and if suction the suction jet pumps, each with a chamber of the refueling vent and the operational venting are connected. Preferably, the Saugstrahlpumpen of a inside the fuel tank supplied to parent fuel pump with fuel as a propellant. By this design, the chambers of the venting device in operation of the motor vehicle constantly empty. Therefore you can designed as float valves valves to the lines the activated carbon filter also in a rollover of the motor vehicle close. Valves of a ventilation device therefore also serve as so-called roll-over valves.
Ein Entweichen von Kraftstoffdämpfen aus dem Kraftstoffbehälter lässt sich besonders gering halten, wenn der Behälter innerhalb des Kraftstoffbehälters angeordnet ist. Durch diese Gestaltung wird die Anzahl der Dichtstellen des Kraftstoffbehälters besonders gering gehalten.One Escape of fuel vapors from the fuel tank let yourself keep particularly low when the container is placed inside the fuel tank is. By this design, the number of sealing points of the Fuel tank especially kept low.
Eine besonders genaue Begrenzung der dem Kraftstoffbehälter zuführbaren Menge an Kraftstoff wird sichergestellt, wenn die Entlüftungsleitung der Betankungsentlüftung bis zu einem vorgesehenen Abschaltpunkt des Kraftstoffbehälters geführt ist und wenn der Behälter unterhalb des Abschaltpunktes angeordnet ist. Damit wird bei Erreichen des Abschaltpunktes die Entlüftung des Kraftstoffbehälters verschlossen. Anschließend kann keine Luft mehr aus dem Kraftstoffbehälter entweichen und damit kein Kraftstoff nachgefüllt werden. Der Abschaltpunkt wird dank der Erfindung von dem freien Ende der Entlüftungsleitung der Betankungsentlüftung festgelegt.A particularly accurate limitation of the fuel tank can be fed Amount of fuel is ensured when the vent line of the refueling vent is guided to a scheduled shutdown of the fuel tank and if the container is arranged below the cut-off point. This will be achieved when the shut-off point the vent closed the fuel tank. Subsequently no air can escape from the fuel tank and thus no Refilled fuel become. The shutdown is thanks to the invention of the free End of the vent line the refueling vent established.
