Abstract
Description
Die Erfindung geht aus von einer Vorrichtung nach der Gattung des Hauptanspruchs.The The invention is based on a device according to the preamble of the main claim.
Es
ist schon eine Vorrichtung zum Fördern von
Kraftstoff aus einem Vorratsbehälter
zu einer Brennkraftmaschine aus der
In der nicht vorveröffentlichten deutschen Patentanmeldung 103 03 390 ist bereits eine Vorrichtung zum Fördern von Kraftstoff vorgeschlagen worden, bei der ein Vorfilter der Düse in einer Treibleitung separat vorgeschaltet ist. Die separate Montage von Vorfilter und Düse in der Treibleitung ist jedoch aufwendig und teuer.In the not previously published German patent application 103 03 390 is already a device to promote been proposed by fuel, in which a pre-filter of the nozzle in one Trebleitung is connected separately upstream. The separate assembly of Pre-filter and nozzle in the Trebleitung is however complicated and expensive.
Vorteile der ErfindungAdvantages of invention
Die erfindungsgemäße Vorrichtung mit den kennzeichnenden Merkmalen des Hauptanspruchs hat demgegenüber den Vorteil, daß auf einfache Art und Weise die Herstellungskosten verringert werden, indem die Düse einteilig mit dem Vorfilter verbunden ist.The inventive device with the characterizing features of the main claim has the Advantage that on simple way the manufacturing costs are reduced by the nozzle is integrally connected to the pre-filter.
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 die Düse mit dem Vorfilter in einem Düsenabschnitt der Treibleitung eingepreßt, eingeclipst, eingeschweißt oder eingeklebt ist, da dies eine besonders günstige Montagelösung ist.Especially is advantageous if the nozzle with the pre-filter in a nozzle section the Trebleitung pressed, clipped, welded or glued, as this is a very convenient mounting solution.
Weiterhin vorteilhaft ist, wenn die Düse mit dem Vorfilter mittels Spritzguß und aus Kunststoff hergestellt ist, da sich die Düse auf diese Weise besonders kostengünstig herstellen läßt.Farther is advantageous if the nozzle with the pre-filter by injection molding and made of plastic is because of the nozzle can be made particularly inexpensive in this way.
Sehr vorteilhaft ist es, wenn der Vorfilter eine Maschenweite von 0,5 Millimetern aufweist, da in der Treibleitung vorhandene Verunreinigungen auf diese Weise besonders effektiv herausgefiltert werden können.Very It is advantageous if the pre-filter has a mesh size of 0.5 Millimeters, as present in the Trebleitung impurities can be filtered out particularly effectively in this way.
In einer vorteilhaften Ausgestaltung ist die Düse deckelförmig mit einem Zylinderabschnitt und einem Bodenabschnitt ausgebildet, wobei der Bodenabschnitt eine Düsenöffnung aufweist. Der Vorfilter ist ringförmig an der der Düsenöffnung abgewandten Stirnseite des Zylinderabschnitts angeordnet, da die Düse und der Vorfilter auf diese Weise besonders einfach mittels Spritzguß herstellbar sind.In According to an advantageous embodiment, the nozzle is lid-shaped with a cylinder section and a bottom portion, wherein the bottom portion a Has nozzle opening. The pre-filter is ring-shaped facing away from the nozzle opening End face of the cylinder portion arranged because the nozzle and the Pre-filter in this way particularly easy to produce by injection molding are.
Darüber hinaus vorteilhaft ist, wenn eine dem Zylinderabschnitt abgewandte Stirnseite des Vorfilters an einer Kanalwandung der Treibleitung dichtend anliegt, da auf diese Weise gewährleistet ist, daß der gesamte Kraftstoff der Treibleitung den Vorfilter der Düse durchströmt.Furthermore is advantageous if a side facing away from the cylinder portion end face of the prefilter sealingly abuts against a duct wall of the treble line, as guaranteed in this way is that the Entire fuel of the Trebleitung flows through the pre-filter of the nozzle.
In einer weiteren vorteilhaften Ausgestaltung ist die Treibleitung in einem Düsenabschnitt abgewinkelt gegenüber der Treibleitung stromauf der Düse und dem Vorfilter und bildet dadurch einen Anschlag, bis zu dem die Düse mit dem integrierten Vorfilter bei der Montage einschiebbar ist.In a further advantageous embodiment is the treble line in a nozzle section angled opposite the treble line upstream of the nozzle and the pre-filter and thereby forms a stop, to which the Nozzle with the integrated prefilter during assembly is inserted.
Vorteilhafter Weise hat die Düse eine Düsenöffnung mit einem Durchmesser von 0,6 bis 2,5 Millimetern.Favorable Way has the nozzle a nozzle opening with a diameter of 0.6 to 2.5 millimeters.
