Abstract
Description
Die Erfindung betrifft eine Kraftstofffördereinheit mit einer zur Förderung von Kraftstoff aus einem Ansaugbereich in einen Druckbereich vorgesehenen Kraftstoffpumpe und mit einem Entlüftungsventil zur Abdichtung des Druckbereichs oder Verbindung des Druckbereichs mit der Umgebung.The The invention relates to a fuel delivery unit with a delivery of fuel from a suction area into a pressure area provided fuel pump and with a vent valve for sealing the pressure area or connecting the pressure area with the environment.
Solche
Kraftstofffördereinheiten
werden in heutigen Kraftfahrzeugen häufig eingesetzt und sind aus
der Praxis bekannt (
Der Elektromotor wird meist von dem geförderten Kraftstoff durchströmt.The The delivered fuel usually flows through the electric motor.
Nachteilig bei der bekannten Kraftstofffördereinheit ist, dass bei nahezu leerem Schwalltopf nach einem langen Stillstand der Kraftstoffpumpe Luft über das Entlüftungsventil in das Gehäuse eindringen kann. Diese Luft muss zunächst bei einem Start der Kraftstoffpumpe über das Entlüftungsventil von dem geförderten Kraftstoff wieder verdrängt werden. Dies führt zu einer zeitlichen Verzögerung beim Druckaufbau sowie zu einer Vermischung von Luft und Kraftstoff.adversely in the known fuel delivery unit is that with a nearly empty surge pot after a long standstill the fuel pump air over that vent valve in the housing can penetrate. This air must first pass through the fuel pump when it starts vent valve from the funded Fuel displaced again become. this leads to at a time lag when building up pressure and mixing air and fuel.
Der Erfindung liegt das Problem zugrunde, ein Eindringen von Luft in das Gehäuse der Kraftstofffördereinheit zu vermeiden.The Invention is based on the problem of air entering the housing the fuel delivery unit to avoid.
Dieses Problem wird erfindungsgemäß dadurch gelöst, dass das der Umgebung zugewandte Ende des Entlüftungsventils mit einem im montierten Zustand der Kraftstofffördereinheit ständig mit Kraftstoff gefüllten Bereich verbunden ist.This According to the invention, this creates a problem solved, that the end of the vent valve facing the environment with an in assembled state of the fuel delivery unit Fuel-filled Area is connected.
Durch diese Gestaltung kann keine Luft über das Entlüftungsventil in das Gehäuse der erfindungsgemäßen Kraftstofffördereinheit eindringen. Deshalb ist das Gehäuse auch nach einem langen Stillstand der Kraftstoffpumpe mit Kraftstoff gefüllt und muss beim Start der Kraftstoffpumpe nicht entlüftet werden. Die bei der Erstbefüllung im Gehäuse vorhandene Luft und bei durch Ausgasen des Kraftstoffs erzeugte Gasblasen können ungehindert über das Entlüftungsventil aus dem Gehäuse abgeführt werden.By this design cannot allow air through the vent valve in the housing the fuel delivery unit according to the invention penetration. That is why the housing even after the fuel pump has been idle for a long time filled and does not need to be bled when the fuel pump starts. The at the first filling in the housing existing air and gas bubbles generated by outgassing the fuel can unhindered over the vent valve out of the housing dissipated become.
Die erfindungsgemäße Kraftstofffördereinheit gestaltet sich konstruktiv besonders einfach, wenn an dem umgebungsseitigen Bereich des Entlüftungsventils eine Leitung angeschlossen ist und wenn die Leitung bis nahe des Ansaugbereichs geführt ist. Hierdurch befindet sich das freie Ende der Leitung auch bei nahezu leerem Schwalltopf jederzeit innerhalb des Kraftstoffs.The Fuel delivery unit according to the invention is structurally particularly simple if on the environmental side Breather valve area a line is connected and if the line is close to the Suction area led is. As a result, the free end of the line is also at almost empty surge pot inside the fuel at all times.
Die Leitung kann beispielsweise einen besonders großen Querschnitt aufweisen und bei der Erstbefüllung abzuführende Luft speichern. Das Eindringen von in der Leitung befindlicher Luft in das Gehäuse der erfindungsgemäßen Kraftstofffördereinheit lässt sich jedoch weitgehend vermeiden, wenn die Leitung ein im Verhältnis zum Volumen des Druckbereichs besonders kleines Volumen aufweist.The For example, the line can have a particularly large cross section and at the first filling dissipated Save air. The penetration of air in the line in the housing the fuel delivery unit according to the invention can however largely avoid if the line is in relation to the Volume of the printing area has a particularly small volume.
Zur weiteren Verringerung des Speichervolumens der Leitung trägt es gemäß einer anderen vorteilhaften Weiterbildung der Erfindung bei, wenn die Leitung eine nahe des Entlüftungsventils zu dem Ansaugbereich geführte Abwinklung aufweist. Durch diese Gestaltung hat die Leitung eine besonders geringe Länge.to according to a further reduction in the storage volume of the line other advantageous development of the invention when the line one near the vent valve led to the suction area Bends. Due to this design, the management has one particularly short length.
Eine Behinderung des Entweichens von Luft aus dem Gehäuse der erfindungsgemäßen Kraftstofffördereinheit über das Entlüftungsventil und die Leitung lässt sich einfach vermeiden, wenn das freie Ende der Leitung im in einen Schwalltopf montierten Zustand der Kraftstofffördereinheit einen vorgesehenen Abstand vom Boden des Schwalltopfes aufweist.A Obstruction of the escape of air from the housing of the fuel delivery unit according to the invention vent valve and the line leaves just avoid yourself if the free end of the line is in one Swirl pot mounted state of the fuel delivery unit provided Distance from the bottom of the baffle.
Die Erfindung lässt zahlreiche Ausführungsformen zu. Zur weiteren Verdeutlichung ihres Grundprinzips ist eine davon in der Zeichnung dargestellt und wird nachfolgend beschrieben.The Invention leaves numerous embodiments to. One of them is to clarify its basic principle shown in the drawing and is described below.
