Abstract
Description
Stand der TechnikState of the art
Die Erfindung geht aus von einer Vorrichtung zum Fördern von Kraftstoff nach der Gattung des Hauptanspruchs.The invention relates to a device for conveying fuel according to the preamble of the main claim.
Es ist schon eine Vorrichtung zum Fördern von Kraftstoff aus der
Vorteile der ErfindungAdvantages of the invention
Die erfindungsgemäße Vorrichtung mit den kennzeichnenden Merkmalen des Hauptanspruchs hat demgegenüber den Vorteil, dass mit einer einzigen Saugstrahlpumpe Kraftstoff sowohl aus der unmittelbaren Umgebung des Speicherbehälters als auch aus von dem Speicherbehälter entfernten Bereichen des Kraftstofftanks angesaugt werden kann. Dies wird erfindungsgemäß erreicht, indem stromauf der Ansaugöffnung eine Anschlusskammer vorgesehen ist, die zumindest zwei Ansaugeingänge aufweist. Einer der Ansaugeingänge saugt Kraftstoff aus der unmittelbaren Umgebung des Speicherbehälters und der andere Ansaugeingang über einen Ansaugschlauch aus von dem Speicherbehälter entfernten Bereichen des Kraftstofftanks an.The device according to the invention with the characterizing features of the main claim has the advantage that with a single ejector fuel can be sucked both from the immediate vicinity of the storage container as well as from remote from the storage tank areas of the fuel tank. This is inventively achieved by upstream of the suction port, a connection chamber is provided which has at least two Ansaugeingänge. One of the suction inlets draws fuel from the immediate vicinity of the storage tank and the other suction inlet via a suction hose from areas of the fuel tank remote from the storage tank.
Durch die in den Unteransprüchen aufgeführten Maßnahmen sind vorteilhafte Weiterbildungen und Verbesserungen der im Hauptanspruch angegebenen Vorrichtung möglich.The measures listed in the dependent claims advantageous refinements and improvements of the main claim device are possible.
Besonders vorteilhaft ist, wenn die Ansaugöffnung für die Saugstrahlpumpe an einem Topfboden des Speicherbehälters angeordnet ist und die Anschlusskammer durch den Topfboden des Speicherbehälters, einen beabstandet zum Topfboden angeordneten Kammerboden und eine zwischen dem Topfboden und dem Kammerboden angeordnete Kammerwand gebildet ist. Die Anschlusskammer wird auf diese Weise unterhalb des Topfbodens des Speicherbehälters vorgesehen.It is particularly advantageous if the suction opening for the suction jet pump is arranged on a pot bottom of the storage container and the connection chamber is formed by the pot bottom of the storage container, a chamber base arranged at a distance from the bottom of the pot and a chamber wall arranged between the bottom of the pot and the bottom of the chamber. The connection chamber is provided in this way below the pot bottom of the storage container.
Weiterhin vorteilhaft ist, wenn der Kammerboden und die Kammerwand an einem separaten Kammergehäuse ausgebildet sind, das an dem Topfboden des Speicherbehälters angeordnet ist, da der Speicherbehälter auf diese Weise unverändert bleiben und die Anschlusskammer abhängig vom Kundenprojekt jeweils einfach an den Speicherbehälter angefügt wird oder nicht. Somit ist eine kostengünstige Modularlösung erreicht.It is also advantageous if the chamber bottom and the chamber wall are formed on a separate chamber housing, which is arranged on the pot bottom of the storage container, since the storage container remain unchanged in this way and the connection chamber depending on the customer project is simply added to the storage tank or not. Thus, a cost-effective modular solution is achieved.
Sehr vorteilhaft ist es, wenn an dem einen Ansaugeingang der Anschlusskammer ein Ansaugschlauch vorgesehen ist, über den Kraftstoff aus vom Speicherbehälter entfernten Bereichen eines Kraftstofftanks ansaugbar ist, da auf diese Weise der von der Saugstrahlpumpe erzeugte Unterdruck auch zum Ansaugen von Kraftstoff aus von dem Speicherbehälter entfernten Bereichen des Kraftstofftanks genutzt wird.It is very advantageous if a suction hose is provided at the one suction inlet of the connecting chamber, via which fuel can be sucked from areas of a fuel tank remote from the storage tank, since in this way the negative pressure generated by the suction jet pump is also removed from the storage tank for drawing in fuel Areas of the fuel tank is used.
Auch vorteilhaft ist, wenn das Verhältnis des Querschnitts des einen Ansaugeingangs zum Querschnitt des anderen Ansaugeingangs zwischen 0,5 und 2 liegt. Auf diese Weise sind die Querschnitte der Ansaugeingänge im Verhältnis zueinander so gewählt, dass ein gleichzeitiges Ansaugen von Kraftstoff über beide Ansaugeingänge gewährleistet ist.It is also advantageous if the ratio of the cross section of one suction inlet to the cross section of the other suction inlet is between 0.5 and 2. In this way, the cross-sections of the suction in relation to each other are chosen so that a simultaneous suction of fuel over both Ansaugeingänge is ensured.
Desweiteren vorteilhaft ist, wenn in der Ansaugöffnung ein Rückschlagventil vorgesehen ist, da auf diese Weise ein unbeabsichtigtes Leerlaufen des Speicherbehälters verhindert wird.Furthermore, it is advantageous if a check valve is provided in the intake opening, as in this way unintentional emptying of the storage container is prevented.
Darüber hinaus vorteilhaft ist, wenn der aus der unmittelbaren Umgebung des Speicherbehälters ansaugende Ansaugeingang ein Rückschlagventil aufweist, da auf diese Weise die Ansaugfunktion der Saugstrahlpumpe bei niedrigem Füllstand im Tank nicht beeinflusst wird.Moreover, it is advantageous if the suction inlet sucking in from the immediate vicinity of the storage container has a check valve, since in this way the suction function of the suction jet pump is not influenced at low filling level in the tank.
