Abstract
Description
Stand der TechnikState of the art
Die Erfindung geht aus von einer Kraftstoffversorgungseinrichtung nach der Gattung des Hauptanspruchs.The The invention is based on a fuel supply device the genus of the main claim.
Es
ist schon eine Kraftstoffversorgungseinrichtung aus der
Vorteile der ErfindungAdvantages of the invention
Die erfindungsgemäße Kraftstoffversorgungseinrichtung mit den kennzeichnenden Merkmalen des Hauptanspruchs hat demgegenüber den Vorteil, dass die Elektrokraftstoffpumpe aus dem Stand der Technik entfallen und die Membranpumpe allein als Vorförderpumpe arbeiten kann, indem der Hochdruckpumpe ein separates Speichervolumen zum Ausgasen von leichtflüchtigen Kraftstoffbestandteilen vorgeschaltet ist. Das Speichervolumen vermeidet, dass Gasblasen in die Hochdruckpumpe gelangen und deren Kraftstoffstrom deutlich verringert. Die leichtflüchtigen Kraftstoffbestandteile können in dem Speichervolumen ausgasen und werden zurück in den Vorratsbehälter geleitet.The Fuel supply device according to the invention with the characterizing features of the main claim has in contrast the advantage that the electric fuel pump from the prior art omitted and the diaphragm pump alone as Vorförderpumpe can work by giving the high pressure pump a separate storage volume upstream of the outgassing of volatile fuel components is. The storage volume avoids gas bubbles in the high pressure pump reach and significantly reduced their fuel flow. The volatile Fuel components may outgas in the storage volume and are returned to the reservoir.
Durch die in den Unteransprüchen aufgeführten Maßnahmen sind vorteilhafte Weiterbildungen und Verbesserungen der im Hauptanspruch angegebenen Kraftstoffversorgungseinrichtung möglich.By the measures listed in the dependent claims are advantageous developments and improvements in the main claim specified fuel supply possible.
Gemäß einer vorteilhaften Ausführung ist das Speichervolumen als separater Behälter ausgeführt, der an einem Gehäuse der Hochdruckpumpe befestigbar ist.According to one advantageous embodiment, the storage volume is as a separate Container executed on a housing the high pressure pump can be fastened.
Besonders vorteilhaft ist, wenn das Speichervolumen zwei Eingänge und zwei Ausgänge aufweist, von denen der erste Eingang mit der Membranpumpe, der zweite Eingang mit einem Rücklauf der Hochdruckpumpe, der erste Ausgang mit dem Eingang der Hochdruckpumpe und der zweite Ausgang mit dem Kraftstofftank verbunden ist.Especially advantageous if the storage volume has two inputs and two outputs, of which the first input with the diaphragm pump, the second input with a return of the High pressure pump, the first outlet with the input of the high pressure pump and the second output is connected to the fuel tank.
Weiterhin vorteilhaft ist, wenn im Rücklauf der Hochdruckpumpe eine Düse vorgesehen ist, da auf diese Weise eine Verwirbelung des im Speichervolumens befindlichen Kraftstoffs erreicht wird. Dadurch kommt es zu einer Gasblasenbildung, die die Ausgasung der leichtflüchtigen Kraftstoffbestandteile fördert.Farther is advantageous if in the return of the high pressure pump a Nozzle is provided, since in this way a turbulence of the fuel in the storage volume is reached. This leads to a gas bubble formation, the outgassing of promotes volatile fuel components.
Auch vorteilhaft ist, wenn der Füllstand im Speichervolumen durch die Position des zweiten Ausgangs eingestellt ist, da auf diese Weise leichtflüchtige Kraftstoffbestandteile über die freie Flüssigkeitsoberfläche in die oberhalb der Flüssigkeitsoberfläche befindliche Gasschicht verdunsten. Zwischen dem flüssigen Kraftstoffvolumen und dem darüberliegenden Gasvolumen besteht eine Temperaturdifferenz.Also is advantageous if the level in the storage volume is set by the position of the second output, up this way over volatile fuel components the free liquid surface in the above the liquid surface located gas layer evaporate. Between the liquid fuel volume and the overlying gas volume is a temperature difference.
Sehr vorteilhaft ist es, wenn der Füllstand im Speichervolumen durch ein am ersten Eingang ausgebildetes Eingangsventil eingestellt ist. Das Eingangsventil ist durch einen an einem Schwimmkörper angeordneten beweglichen Ventilkörper gebildet, der mit einem Ventilsitz des ersten Eingangs zusammenwirkt und den Füllstand im Speichervolumen steuert. Auf diese Weise wird die ständige Durchströmung und Durchmischung des Speichervolumens mit leichtflüchtigen Kraftstoffanteilen aus dem Vorratsbehälter verhindert.Very It is advantageous if the level in the storage volume set by an input valve formed at the first input is. The input valve is through a on a float arranged movable valve body formed with a valve seat of the first input interacts and the level in the storage volume controls. In this way, the permanent becomes Flow through and mixing of the storage volume with volatile fuel from the reservoir prevented.
Desweiteren vorteilhaft ist, wenn im Speichervolumen ein Heizmittel zum Beheizen des Speichervolumens vorgesehen ist, da auf diese Weise die Verdunstung der leichtflüchtigen Kraftstoffbestandteile gefordert wird. Gemäß einer vorteilhaften Ausführung ist das Heizmittel eine elektrische Heizspule oder eine elektrische Heizwendel.Furthermore is advantageous if a heating means for heating in the storage volume the storage volume is provided, since in this way the evaporation the volatile fuel components is required. According to an advantageous embodiment the heating means is an electric heating coil or an electric heating coil Heating coil.
Darüber hinaus vorteilhaft ist, wenn das Heizmittel derart angeordnet ist, dass das Gasvolumen des Speichervolumens beheizt wird, da eine erhöhte Temperaturdifferenz zwischen Gas- und Flüssigkeitsvolumen die Verdunstung weiter fördert.About that is also advantageous if the heating means is arranged such that the gas volume of the storage volume is heated, as an increased Temperature difference between gas and liquid volume the evaporation further promotes.
