Abstract
Es sind schon Vorrichtungen zum Fördern von Kraftstoff bekannt, mit einem Förderaggregat, das Kraftstoff druckerhöht über eine Druckleitung an eine Brennkraftmaschine liefert, wobei in der Druckleitung ein Rückschlagventil und ein Filter vorgesehen ist und von der Druckleitung stromab des Filters eine Druckentlastungsleitung mit einem Druckentlastungsventil abzweigt. Nachteilig ist, dass der Öffnungsdruck des Druckentlastungsventils über dem vom Förderaggregat aufgebauten maximalen Systemdruck liegen muss, da das Förderaggregat ansonsten im Betrieb den elektronisch geregelten Systemdruck nicht aufbauen könnte. Hierdurch wird die Druckleitung einschließlich des Filters im Abstellfall mit dem hohen Öffnungsdruck über einen längeren Zeitraum druckbelastet, so dass die Druckleitung, insbesondere der Filter, dementsprechend druckfest auszulegen ist. Die erfindungsgemäße Vorrichtung wird dahingehend verbessert, dass die Regelung des Förderaggregates unabhängig von der Einstellung des Druckentlastungsventils ist. Erfindungsgemäß ist vorgesehen, dass der Öffnungsdruck des Druckentlastungsventils (23) unter dem vom Förderaggregat (1) aufgebauten maximalen Systemdruck liegt und in der Druckentlastungsleitung (22) eine Drossel (24) vorgesehen ist.There are already known devices for conveying fuel, with a delivery unit, the pressure increases fuel via a pressure line to an internal combustion engine, wherein in the pressure line, a check valve and a filter is provided and branches off from the pressure line downstream of the filter, a pressure relief line with a pressure relief valve. The disadvantage is that the opening pressure of the pressure relief valve must be above the maximum system pressure built up by the delivery unit, since otherwise the delivery unit could not build up the electronically controlled system pressure during operation. As a result, the pressure line including the filter is pressure-loaded in Abstellfall with the high opening pressure over a longer period of time, so that the pressure line, in particular the filter is to be designed accordingly flameproof. The device according to the invention is improved to the effect that the control of the delivery unit is independent of the setting of the pressure relief valve. According to the invention, it is provided that the opening pressure of the pressure relief valve (23) is below the maximum system pressure built up by the delivery unit (1) and a throttle (24) is provided in the pressure relief line (22).
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 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 der Öffnungsdruck des Druckentlastungsventils unter dem vom Förderaggregat aufgebauten Systemdruck liegen kann, indem in der Druckentlastungsleitung eine Drossel vorgesehen ist. Nach dem Abstellen des Förderaggregates sinkt der Druck in der Druckleitung unter den Systemdruck auf den Öffnungsdruck des Druckentlastungsventils ab. Dies hat den Vorteil, dass die Druckbelastung der Druckleitung innerhalb und außerhalb des Vorratsbehälters reduziert wird, so dass sich durch die geringeren Druckanforderungen geringere Herstellungskosten ergeben. Die Drossel verringert die über das Druckbegrenzungsventil abströmende Verlustmenge, so dass die Regelung des Förderaggregates unabhängig von der Einstellung des Druckentlastungsventils ist.The inventive device with the characterizing features of the main claim has the Advantage that the opening pressure of the pressure relief valve under the system pressure built up by the delivery unit can lie by providing a throttle in the pressure relief line is. After switching off the delivery unit the pressure in the pressure line drops below the system pressure to the opening pressure of the pressure relief valve. This has the advantage that the pressure load the pressure line inside and outside of the reservoir reduced becomes, so that by the smaller pressure requirements lower Cost of production result. The throttle reduces the over the Pressure relief valve outflowing Loss amount, so that the control of the delivery unit regardless of the setting of the pressure relief valve is.
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 Drossel stromauf des Druckentlastungsventils angeordnet ist, da auf diese Weise die mechanische Belastung des Druckbegrenzungsventils reduziert wird.Especially is advantageous if the throttle upstream of the pressure relief valve is arranged, as in this way the mechanical load of the pressure relief valve is reduced.
