Abstract
Description
Die Erfindung betrifft eine Kraftstofffördereinheit für ein Kraftfahrzeug mit einer zur Anordnung in einem Kraftstoffbehälter vorgesehenen, eine Kraftstoffpumpe aufweisenden Baugruppe und mit einem zum Verschließen einer Öffnung des Kraftstoffbehälters vorgesehenen, mit der Baugruppe der Kraftstoffpumpe verbundenen Flansch, mit einem in einer von der Kraftstoffpumpe durch den Flansch geführten Vorlaufleitung und mit einem in der Vorlaufleitung angeordneten Druckregler.The invention relates to a fuel delivery unit for a Motor vehicle with a device intended for arrangement in a fuel tank, a fuel pump assembly and with one for closing an opening of the Fuel tank provided, connected to the assembly of the fuel pump Flange, with one in one by the fuel pump through the flange led flow line and with a pressure regulator arranged in the flow line.
Solche Kraftstofffördereinheiten werden in heutigen Kraftfahrzeugen häufig eingesetzt und sind aus der Praxis bekannt. Hierbei wird der Druckregler meist als vormontierte Einheit in dem Flansch eingesetzt. Nachteilig bei der bekannten Kraftstofffördereinheit ist, dass die vormontierte Einheit des Druckreglers und der Flansch hierdurch besonders aufwändig zu fertigen sind. Zudem entstehen im Druckregler und damit unmittelbar an der Wandung des Kraftstoffbehälters Strömungs- und Schaltgeräusche, die außerhalb des Kraftstoffbehälters sehr störend sind.Such fuel delivery units are often used in today's motor vehicles and are off known in practice. Here the pressure regulator is mostly pre-assembled Unit inserted in the flange. A disadvantage of the known Fuel delivery unit is that the pre-assembled unit of the pressure regulator and the flange this makes it particularly complex are to be manufactured. In addition, arise in the pressure regulator and thus immediately on the wall of the fuel tank flow and switching noises, the outside the fuel tank very annoying are.
Man könnte daran denken, den Druckregler außerhalb des Flansches in der Vorlaufleitung anzuordnen. Hierdurch erhöht sich jedoch der Aufwand für die Montage des Druckreglers.You could remember the pressure regulator outside the flange in the flow line. This increases however the effort for that Installation of the pressure regulator.
Der Erfindung liegt das Problem zugrunde, eine Kraftstofffördereinheit der eingangs genannten Art so zu gestalten, dass sie besonders kostengünstig zu fertigen und zu montieren ist.The invention is based on the problem, a Fuel delivery unit of the type mentioned at the outset so that they are particularly cost-effective manufacture and assemble.
Dieses Problem wird erfindungsgemäß dadurch gelöst, dass zumindest ein Teilbereich eines Gehäuse des Druckreglers einstückig mit einem Bauteil der Baugruppe der Kraftstoffpumpe gefertigt ist.This problem is solved according to the invention solved, that at least a portion of a housing of the pressure regulator with a component of the assembly of the fuel pump is manufactured.
Durch diese Gestaltung kann auf die Fertigung eines Teils des Gehäuses des Druckreglers verzichtet werden, da dieses von dem unterhalb des Flansches des Bauteils der Baugruppe gebildet ist. Dies führt zu einer Verringerung der Anzahl von Bauteilen der erfindungsgemäßen Kraftstofffördereinheit. Der Flansch der erfindungsgemäßen Kraftstofffördereinheit lässt sich zudem als konstruktiv einfaches Bauteil besonders kostengünstig fertigen. Da die unterhalb des Flansches angeordneten Bauteile der Baugruppe meist ohnehin kompliziert aufgebaut sind, führt die Anordnung des Druckreglers an diesem Bauteil nur zu einer unwesentlichen Erhöhung des Fertigungsaufwandes. Demgegenüber wird eine zusätzliche Maschinenbelegung als auch ein zusätzliches Werkzeug für den ansonsten separaten Druckregler eingespart. Daher lässt sich die erfindungsgemäße Kraftstofffördereinheit besonders kostengünstig fertigen und montieren. Ein weiterer Vorteil dieser Gestaltung besteht darin, dass Strömungs- und Schaltgeräusche des Druckreglers innerhalb des Kraftstoffbehälters entstehen und deshalb nur gedämpft nach außen vordringen können.Through this design, the Manufacturing part of the housing of the pressure regulator can be dispensed with, since this is from below the flange of the component of the assembly is formed. This leads to a Reduction in the number of components of the fuel delivery unit according to the invention. The Flange of the fuel delivery unit according to the invention let yourself also manufacture as a structurally simple component at particularly low cost. Since the components of the assembly arranged below the flange are usually complex anyway, the arrangement of the pressure regulator leads on this component only to an insignificant increase in production costs. In contrast, will be an additional Machine assignment as well as an additional tool for the otherwise separate pressure regulator saved. Therefore, the fuel delivery unit according to the invention can particularly inexpensive manufacture and assemble. Another advantage of this design is in that flow and switching noises of the pressure regulator within the fuel tank and therefore just steamed outward can penetrate.
Häufig ist innerhalb des Schwalltopfes ein Ringfilter der Kraftstoffpumpe angeordnet. Bei solchen Kraftstofffördereinheiten lässt sich der Druckregler mit besonders geringem Aufwand montieren, wenn das Bauteil der Baugruppe der Kraftstoffpumpe zumindest ein Teil eines Gehäuses eines in dem Schwalltopf angeordneten Filters ist.Frequently is a ring filter of the fuel pump inside the surge pot arranged. With such fuel delivery units assemble the pressure regulator with very little effort if that Component of the assembly of the fuel pump at least part of a housing of a filter arranged in the surge pot.
Die Fertigung der erfindungsgemäßen Kraftstofffördereinheit gestaltet sich besonders einfach, wenn das Bauteil der Baugruppe der Kraftstoffpumpe eine Abdeckung der Kraftstoffpumpe oder eine Abdeckung eines Schwalltopfes ist.The manufacture of the fuel delivery unit according to the invention is particularly easy if the component of the assembly the fuel pump a cover of the fuel pump or a Cover of a baffle is.
Zur weiteren Erhöhung der Integrationsdichte der Bauteile der erfindungsgemäßen Kraftstofffördereinheit trägt es bei, wenn das Bauteil der Baugruppe der Kraftstoffpumpe eine Aufnahme für ein Bauteil, insbesondere für einen Ventilsitz des Druckreglers hat.To further increase the integration density of the components of the fuel delivery unit according to the invention wear it at if the component of the fuel pump assembly is a receptacle for a component, especially for has a valve seat of the pressure regulator.
Das den Druckregler aufnehmende Bauteil lässt sich gemäß einer anderen vorteilhaften Weiterbildung der Erfindung besonders kostengünstig in einer axial entformbaren Form fertigen, wenn die Aufnahme parallel zu einem Anschlussstutzen der Vorlaufleitung ausgerichtet ist.The component holding the pressure regulator can be according to one other advantageous development of the invention in particularly inexpensive produce an axially demoldable shape when the receptacle is parallel is aligned to a connecting piece of the flow line.
Zur weiteren Vereinfachung der Montage des Druckreglers trägt es gemäß einer anderen vorteilhaften Weiterbildung der Erfindung bei, wenn ein Deckel des Druckreglers mit dem Bauteil der Baugruppe der Kraftstoffpumpe verbunden ist.To further simplify the assembly of the Pressure regulator carries it according to one other advantageous development of the invention when a lid of the pressure regulator with the component of the fuel pump assembly connected is.
Zur weiteren Verringerung der Fertigungskosten der erfindungsgemäßen Kraftstofffördereinheit trägt es bei, wenn eine mit dem Druckregler verbundene Abregelleitung einstückig mit dem Bauteil der Baugruppe der Kraftstoffpumpe gefertigt ist. Die Abregelleitung lässt sich beispielsweise mit einer zu einer Saugstrahlpumpe führenden Treibmittelleitung verbinden.To further reduce manufacturing costs the fuel delivery unit according to the invention wear it at, if a discharge line connected to the pressure regulator is integral with the component of the fuel pump assembly is manufactured. The shutdown line let yourself for example with one leading to a suction jet pump Connect the propellant line.
Der Druckregler ist gemäß einer anderen vorteilhaften Weiterbildung der Erfindung für Wartungsarbeiten oder Einstellungen leicht zugänglich, wenn er von der die Kraftstoffpumpe aufweisenden Baugruppe absteht.The pressure regulator is according to one another advantageous development of the invention for maintenance work or settings easily accessible when it protrudes from the assembly having the fuel pump.
Die Erfindung lässt zahlreiche Ausführungsformen zu. Zur weiteren Verdeutlichung ihres Grundprinzips sind zwei davon in der Zeichnung dargestellt und werden nachfolgend beschrieben. Diese zeigt inThe invention leaves numerous embodiments to. To further clarify its basic principle, two of them are shown in the drawing and are described below. This shows in
