Description

Die Erfindung betrifft eine Brennstoffördereinheit mit Speichertopf für den Einbau in einen Brennstofftank eines Kraftfahrzeuges nach dem Oberbegriff des Patent­ anspruchs 1.The invention relates to a fuel delivery unit with storage pot for installation in a fuel tank of a motor vehicle according to the preamble of the patent claim 1.

Mit einer solchen aus der DE 35 10 890 C2 bekannten Brennstoffördereinheit wird sicher­ gestellt, daß bei teilentleertem Brennstofftank bei Kurven- oder Bergfahrt ausreichend Brennstoff vor der Brennstoffpumpe verbleibt, um einen sicheren Betrieb der Brennkraftmaschine zu gewährleisten.With such a fuel delivery unit known from DE 35 10 890 C2 is safe placed that with partially empty fuel tank when cornering or driving uphill sufficient fuel remains in front of the fuel pump to ensure safe To ensure operation of the internal combustion engine.

Der Brennstoffzulauf zum Speichertopf bzw. zu einer Vorpumpe erfolgt in der Regel über einen Brennstoffilter, der feinmaschig ausgeführt ist und bei Benetzung mit Brennstoff (Oberflächenspannung) eine Rücklaufsperre bewirkt, d. h. der einmal in den Speichertopf gelangte Brennstoff kann durch den Brennstoffilter nicht mehr zurückfließen.The fuel supply to the storage pot or to a backing pump is usually done via a fuel filter, which is finely meshed and with wetting Fuel (surface tension) causes a backstop, d. H. the once in Fuel that has reached the storage tank can no longer pass through the fuel filter flow back.

Obwohl sich diese Ausführungen sehr bewährt haben, tritt in einigen seltenen Fällen ein Ausfall der Brennstofförderung ein, wenn eine Luft- oder Dampfblase unter dem Brennstoffilter auftritt. Hierdurch wird offensichtlich der Brennstoffzulauf zur Vorpumpe gestört.Although these designs have proven very successful, they occur in a few rare cases a failure to deliver fuel if there is an air or vapor bubble below the Fuel filter occurs. This obviously turns the fuel supply to Backing pump faulty.

Hiervon ausgehend stellt sich die Erfindungsaufgabe, Maßnahmen aufzufinden, mit denen ein ungestörter Brennstoffzulauf erreicht wird.Proceeding from this, the task of the invention to find measures also arises where an undisturbed fuel supply is achieved.

Diese Aufgabe ist bei einer gattungsgemäßen Einheit dadurch gelöst worden, daß der unter dem Ansaugstutzen der Brennstoffpumpe befindliche Filterbereich undurchlässig ausgeführt ist, und daß der sich an den undurchlässigen Filterbereich anschließende Filterbereich von innen nach außen nach oben hin ansteigend aus­ geführt ist.This object has been achieved in a generic unit in that the filter area located under the intake port of the fuel pump is impermeable, and that the attached to the impermeable filter area  subsequent filter area increasing from the inside outwards is led.

Ein Ausführungsbeispiel der Erfindung ist in der Zeichnung dargestellt und wird nachfolgend beschrieben.An embodiment of the invention is shown in the drawing and will described below.

Diese zeigt einen Schnitt durch eine Brennstoffördereinheit 1 mit Speichertopf 2 und einer Brennstoffpumpe 3, deren Ansaugstutzen 4 in eine Vorkammer 5 hineinragt, die über ein Brennstoffilter 6 mit dem Brennstofftank 7 verbunden ist und mit Ab­ stützfüßen 8 gegen den Tankboden 9 gedrückt ist, so daß von allen Seiten Brenn­ stoff zufließen kann.This shows a section through a fuel delivery unit 1 with storage pot 2 and a fuel pump 3 , the intake manifold 4 protrudes into a prechamber 5 , which is connected via a fuel filter 6 to the fuel tank 7 and with support feet 8 pressed against the tank bottom 9 , so that fuel can flow in from all sides.

Erfindungsgemäß weist das Brennstoffilter 6 nun die Merkmale auf, daß der unter dem Ansaugstutzen 4 der Brennstoffpumpe 3 befindliche Filterbereich 10 undurch­ lässig ausgeführt ist, und daß der sich an den undurchlässigen Filterbereich 10 anschließende Filterbereich 11 von innen nach außen nach oben hin ansteigend ausgeführt ist, in der Darstellung ist der ansteigende Filterbereich 11 kegel­ mantelförmig ausgeführt.According to the invention, the fuel filter 6 now has the features that the filter area 10 located under the intake port 4 of the fuel pump 3 is made impermeable, and that the filter area 11 adjoining the impermeable filter area 10 is designed to rise from the inside outwards, in the illustration, the rising filter area 11 is made cone-shaped.

Mit dieser Maßnahme wird erreicht, daß ggf. unter das Brennstoffilter 6 gelangende Luft- oder Gasblasen nicht von der Brennstoffpumpe 3 angesaugt werden und den Ansaugstutzen 4 dabei verschließen können.With this measure it is achieved that any air or gas bubbles that get under the fuel filter 6 are not sucked in by the fuel pump 3 and can close the intake manifold 4 .

Die unter das Brennstoffilter 6 gelangenden Luft- oder Gasblasen steigen an dem kegelmantelförmigen Filterbereich 11 nach oben und werden dabei nach außen geführt, wo sie in bezug auf die Brennstoffansaugung ohne Wirkung bleiben.The air or gas bubbles coming under the fuel filter 6 rise upwards on the conical jacket-shaped filter area 11 and are guided outwards, where they remain ineffective with respect to the fuel intake.

Vorteilhafterweise kann vorgesehen werden, daß sich der undurchlässige Filterbereich 10 am Tankboden 9 abstützt und/oder kegel- oder kalottenförmig ausgeführt ist, wobei das Filtergewebe an Rippen 12 in der Vorkammer 5 abgestützt ist. It can advantageously be provided that the impermeable filter area 10 is supported on the tank bottom 9 and / or is conical or dome-shaped, the filter fabric being supported on ribs 12 in the prechamber 5 .

Mit der Brennstoffördereinheit nach der Erfindung liegt eine leicht zu realisierende Ausführung vor.With the fuel delivery unit according to the invention is an easy to implement Execution before.
