Description
Stand der TechnikState of the art
Die Erfindung geht aus von einer Vorrichtung zum Fördern von Kraftstoff nach der Gattung des Hauptanspruchs.The The invention is based on a device for conveying fuel after the Genus of the main claim.
Es ist schon eine Vorrichtung bekannt mit einem in einem Kraftstofftank anordnenbaren Speicherbehälter und einer in den Speicherbehälter hineinreichenden Saugleitung einer Standheizung. Die Saugleitung ragt mit einer vorbestimmten Länge in den Speicherbehälter hinein, wobei ein vorbestimmter Abstand zwischen dem Ende der Saugleitung und einem Boden des Speicherbehälters verbleibt, so dass die Standheizung den Speicherbehälter nicht vollständig entleeren kann. Der vorbestimmte Abstand zwischen dem Ende der Saugleitung und dem Boden des Speicherbehälters entspricht einem vorbestimmten Restvolumen im Speicherbehälter, das von der Standheizung nicht verbraucht werden kann. Dieses Restvolumen schwankt innerhalb relativ großer Toleranzen, da die Länge der Saugleitung bei der Herstellung variiert, die Lage der Saugleitung bei der Montage Toleranzen unterworfen ist und sich die Länge der Saugleitung durch Quellung im Kraftstoff verändert.It already a device is known with a in a fuel tank disposable storage container and one reaching into the storage container Suction line of a parking heater. The suction line protrudes with a predetermined Length in the storage tank in, with a predetermined distance between the end of the suction line and a bottom of the storage container remains so that the heater does not the storage tank Completely can empty. The predetermined distance between the end of the suction line and the bottom of the storage container corresponds to a predetermined residual volume in the storage container, the from the heater can not be consumed. This residual volume varies within relatively large Tolerances, as the length the suction line varies during manufacture, the position of the suction line at the assembly is subject to tolerances and the length of the Suction line changed by swelling in the fuel.
In dem Speicherbehälter entstehen durch das Umpumpen des Kraftstoffs große Turbulenzen, so dass der in dem Speicherbehälter befindliche Kraftstoff viele Gasblasen aufweist. Wenn die Gasblasen in die Saugleitung der Standheizung gelangen, kommt es zu einer ungünstigen Verbrennung, die zu verstärkten Geräuschen und zu einer Rauchentwicklung führt. Um dies zu vermeiden ist am Eingang der Saugleitung ein Filter angeordnet, das die Gasblasen abweist. Dieser Filter ist jedoch vergleichsweise aufwendig zu montieren.In the storage container caused by the pumping of the fuel large turbulences, so that the in the storage container Fuel has many gas bubbles. When the gas bubbles get into the suction line of the auxiliary heater, it comes to a unfavorable Combustion that intensified sounds and leads to smoke. In order to avoid this, a filter is arranged at the inlet of the suction line, that repels the gas bubbles. This filter is however comparatively consuming to assemble.
Vorteile der ErfindungAdvantages of the invention
Die erfindungsgemäße Vorrichtung mit den kennzeichnenden Merkmalen des Hauptanspruchs hat demgegenüber den Vorteil, dass der Filter am Eingang der Saugleitung eingespart werden kann, indem der Speicherbehälter ein separates Reservoir aufweist, in das die Saugleitung der Standheizung hineinragt. Der in dem separaten Reservoir befindliche Kraftstoff ist strömungsberuhigt, so dass dort keine oder nur wenige Gasblasen vorliegen. Durch den Entfall des Filters wird die Montage der Vorrichtung deutlich vereinfacht und kostengünstiger. Das von der Standheizung nicht verbrauchbare Restvolumen im Speicherbehälter ist innerhalb sehr enger Toleranzen einhaltbar, da sich die Lage und Länge der Saugleitung im separaten Reservoir nur sehr geringfügig auf das Restvolumen auswirken.The inventive device with the characterizing features of the main claim has the Advantage that the filter at the inlet of the suction line can be saved can by removing the storage tank a separate reservoir, in which the suction line of the auxiliary heater protrudes. The fuel in the separate reservoir is calm, so that there are no or only a few gas bubbles. By the omission the filter assembly of the device is significantly simplified and cheaper. The non-consumable by the heater residual volume in the storage tank is within very tight tolerable, as the situation and Length of Suction line in the separate reservoir only very slightly affect the residual volume.
Durch die in den Unteransprüchen aufgeführten Maßnahmen sind vorteilhafte Weiterbildungen und Verbesserungen der im Hauptanspruch angegebenen Vorrichtung möglich.By in the subclaims listed activities are advantageous developments and improvements in the main claim specified device possible.
Besonders vorteilhaft ist, wenn das separate Reservoir ein Teilvolumen des Speicherbehälters ist, da auf diese Weise zwei Teilvolumina gebildet sind, wobei das eine Teilvolumen ab einem vorbestimmten Füllstand nahezu vollständig gegenüber dem anderen getrennt ist.Especially is advantageous if the separate reservoir is a partial volume of storage container is because in this way two partial volumes are formed, the a partial volume from a predetermined level almost completely opposite to the other is separate.
Weiterhin vorteilhaft ist, wenn das separate Reservoir an einem Boden des Speicherbehälters angeordnet ist, da es auf diese Weise bereits bei geringen Füllständen im Speicherbehälter mit Kraftstoff wiederbefüllt wird.Farther is advantageous if the separate reservoir at a bottom of the Storage container arranged is because it is already at low levels in this way storage container refilled with fuel becomes.
Außerdem vorteilhaft ist, wenn das separate Reservoir am Umfang des Speicherbehälters und damit an dessen Rand angeordnet ist, da dort die Turbulenzen am geringsten sind.In addition, advantageous is when the separate reservoir on the perimeter of the storage tank and so that is arranged at the edge, since there the turbulence on are lowest.
Sehr vorteilhaft ist es, wenn das separate Reservoir nach oben hin offen ausgeführt ist, da es auf diese Weise über den Speicherbehälter wiederbefüllbar ist Auch vorteilhaft ist, dass das separate Reservoir mittels einer Trennwand von dem übrigem Volumen des Speicherbehälters getrennt ist, da dies eine sehr einfache und kostengünstige Ausführungsform ist. Die Höhe der Trennwand stellt das von der Standheizung nicht verbrauchbare Restvolumen sehr genau ein. Die Trennwand ist einstückig mit dem Speicherbehälter verbunden, so dass das separate Reservoir einstückig am Speicherbehälter ausgebildet ist. Das separate Reservoir kann aber auch als separates Teil ausgeführt sein und fest mit dem Speicherbehälter verbunden werden.Very It is advantageous if the separate reservoir is open at the top accomplished is because it's over that way the storage tank refillable It is also advantageous that the separate reservoir by means of a Partition wall of the remaining volume of the storage container is disconnected, as this is a very simple and inexpensive embodiment is. The height the partition provides that of the auxiliary heater not consumable Residual volume very accurately. The partition is in one piece with the storage container connected, so that the separate reservoir integrally formed on the storage container is. The separate reservoir can also be designed as a separate part and stuck with the storage tank get connected.
Desweiteren vorteilhaft ist, wenn die Höhe der Trennwand geringer ist als die Höhe des Speicherbehälters, da der Standheizung auf diese Weise auch Kraftstoff aus dem übrigen Speicherbehälter zur Verfügung steht, jedoch nur bis zu einem der Höhe der Trennwand entsprechenden Füllstand. Außerdem wird das separate Reservoir auf diese Weise bereits bei geringer Füllhöhe im Speicherbehälter wiederbefüllt.Furthermore is advantageous if the height of Partition is less than the height the storage container, since the heater in this way also fuel from the rest of the storage tank to disposal is, but only up to one of the height of the partition corresponding Level. In addition, will the separate reservoir refilled in this way even at low level in the storage tank.
