Description

Die Erfindung betrifft die Anordnung eines Kraftstofftanks und zugeordneter Aggregate, wie Kraftstoffpumpe, Kraftstoff­ filter, Tankentlüftung, Drucksensor, Füllstandsgeber u. dgl., insbesondere in Kraftfahrzeugen.The invention relates to the arrangement of a fuel tank and associated units, such as fuel pump, fuel filter, tank ventilation, pressure sensor, level sensor u. the like, especially in motor vehicles.

Bei bisherigen Kraftfahrzeugen ist die Anordnung des Kraftstofftanks sowie zugehöriger Aggregate des Kraft­ stoffsystems vergleichsweise aufwendig, weil die Aggre­ gate überwiegend entfernt vom Tank und je nach Fahrzeug­ typ an unterschiedlichen Stellen des Fahrzeuges angeordnet werden müssen, je nach dem zur Verfügung stehenden Raum im jeweiligen Fahrzeug.In previous motor vehicles, the arrangement of the Fuel tanks and related aggregates of the force system is comparatively complex because the aggregate gate mostly away from the tank and depending on the vehicle arranged at different locations on the vehicle depending on the space available in the respective vehicle.

Darüber hinaus muß auch der Kraftstofftank an das jeweilige System angepaßt sein, wobei je nach Anordnung entsprechender Systemteile auch unterschiedliche Anschlüsse bzw. Anschluß­ konfigurationen am Tank vorhanden sein müssen.In addition, the fuel tank must also be connected to the respective System to be adapted, depending on the arrangement appropriate System parts also different connections or connection configurations must be available on the tank.

Aufgabe der Erfindung ist es nun, den Montageaufwand bei einer Anordnung der eingangs angegebenen Art wesentlich zu vermindern.The object of the invention is now to the assembly effort an arrangement of the type specified essential to diminish.

Diese Aufgabe wird erfindungsgemäß gelöst durch einen im Tank angeordneten, eine zugeordnete Tanköffnung abschließen­ den Modul, welcher zumindest einen Teil der Aggregate um­ faßt, insbesondere solche Aggregate, die nach außen führende Leitungen oder Anschlüsse benötigen, wobei diese Leitungen oder Anschlüsse am Modul angeordnet bzw. angeschlossen sind.This object is achieved by an im Arranged tank, complete an assigned tank opening  the module, which is at least a part of the aggregates summarizes, especially those aggregates that lead to the outside Lines or connectors need these lines or connections are arranged or connected to the module.

Die Erfindung beruht auf dem allgemeinen Gedanken, den Innen­ raum des Kraftstofftanks zur Unterbringung wesentlicher Teile des Kraftstoffsystems auszunutzen und dazu die zugehörigen Systemteile zu einem vormontierbaren und weitestgehend stan­ dardisierbaren Modul zusammenzufassen. Da der Kraftstofftank in einem Kraftfahrzeug typischerweise an kollisionsgeschütz­ ten Orten untergebracht ist, wird bei der Erfindung zwangs­ läufig auch eine entsprechend geschützte Unterbringung der zugeordneten Kraftstoffsystemteile gewährleistet. Die auf­ grund der Erfindung theoretisch in Kauf zu nehmende Ver­ minderung der maximalen vom Tank aufnehmbaren Kraftstoffmenge kann in der Praxis vernachlässigt werden, weil das vom Modul gegebenenfalls verdrängte Kraftstoffvolumen sehr gering ist.The invention is based on the general idea, the inside space of the fuel tank to accommodate essential parts of the fuel system and the associated System parts to a pre-assembled and largely stan summarize the customizable module. Because the fuel tank in a motor vehicle typically on collision protection Th places is housed in the invention is compulsory a correspondingly protected accommodation of the assigned fuel system parts guaranteed. The on due to the invention theoretically to be accepted Ver reduction in the maximum amount of fuel that can be taken up by the tank can be neglected in practice because of the module possibly displaced fuel volume is very small.

Ein besonderer Vorzug der Erfindung liegt in deutlich ver­ minderten Montagekosten, da der Modul und dementsprechend wesentliche Teile des Kraftstoffsystems komplett vorgefer­ tigt werden können. Darüber hinaus wird die Wartung verein­ facht.A particular advantage of the invention lies in ver reduced assembly costs because of the module and accordingly essential parts of the fuel system completely prefabricated can be done. In addition, maintenance is combined fold.

Im übrigen wird hinsichtlich bevorzugter Merkmale der Er­ findung auf die Ansprüche sowie die nachfolgende Beschreibung einer besonders bevorzugten Ausführungsform verwiesen, die anhand der Zeichnung erläutert wird.Incidentally, the Er Find on the claims and the description below referred to a particularly preferred embodiment, the is explained with reference to the drawing.

Fig. 3 eine Draufsicht auf die Oberseite des Moduls ent­ sprechend dem Pfeil III in Fig. 1. Fig. 3 is a plan view of the top of the module accordingly to the arrow III in FIG. 1.

Ein in Fig. 1 nur teilweise sichtbarer Kraftstofftank 1 besitzt neben einem in der Zeichnung nicht dargestellten Einfüllstutzen an seiner Oberseite eine größere Öffnung, die vertikal oberhalb des tiefsten Bereiches der Tankunter­ seite angeordnet ist, vorzugsweise an der Oberseite eines domartigen Bereiches 1′ der Tankoberseite.A in Fig. 1 only partially visible fuel tank 1 has in addition to a filler neck, not shown in the drawing, at its top a larger opening, which is arranged vertically above the deepest area of the tank bottom side, preferably at the top of a dome-like area 1 'of the tank top.

Unterhalb dieser Öffnung ist im Tank 1 an der Tankunterseite ein Schlingertopf 2 angeordnet, welcher vorzugsweise als Kunststoffteil ausgebildet und nach oben offen ist. Der Schlingertopf 2 besitzt mehrere vertikale Wände 3, die einen zentralen Bereich 4 spiralig umschließen, so daß einerseits durch die zwischen den Wänden 3 verbleibenden spiraligen Kanäle Kraftstoff in den zentralen Bereich 4 nachfließen kann und andererseits eine schnelle Entleerung des zentralen Bereiches 4 bei Schwallbewegungen des Kraft­ stoffes verhindert wird.Below this opening, a swirl pot 2 is arranged in the tank 1 on the underside of the tank, which is preferably designed as a plastic part and is open at the top. The swirl pot 2 has a plurality of vertical walls 3 , which spirally enclose a central region 4 , so that fuel can flow into the central region 4 through the spiral channels remaining between the walls 3 and, on the other hand, rapid emptying of the central region 4 in the event of surge movements of the force is prevented.

In der oberseitigen Öffnung des Tanks 1 im Bereich 1′ ist ein sich vertikal bis in den zentralen Bereich 4 des Schlin­ gertopfes 2 erstreckender Modul 5 angeordnet, welcher in Einbaulage die genannte Öffnung dicht verschließt. Dabei können die miteinander zusammenwirkenden Teile der Öffnung und des Moduls 5 nach Art eines Bajonettverschlusses ausge­ bildet sein. Vorzugsweise sind die Öffnung und der Modul 5 so ausgebildet, daß eine Montage des Moduls 5 nur in einer richtigen Lage möglich ist. In the top opening of the tank 1 in the area 1 'a vertically extending into the central area 4 of the Schlin gertopfes 2 module 5 is arranged, which tightly closes said opening in the installed position. The interacting parts of the opening and the module 5 can be formed out in the manner of a bayonet catch. The opening and the module 5 are preferably designed such that the module 5 can only be installed in a correct position.

Der Modul 5 besitzt ein im wesentlichen säulenartiges, rohrförmiges Gehäuse 6 mit einem größeren Fenster in der Gehäuseumfangswand. Im unteren Teil des Gehäuses 6 ist eine Kraftstoffpumpe 7 mit nach unten aus dem Gehäuse 6 heraus­ ragenden Sauganschluß 8 und einem an die Druckseite der Pumpe 7 angeschlossenen, mit der Pumpe kombinierten Druck­ regler 9 angeordnet, über den die Kraftstoffpumpe 7 mit dem Eingang eines Kraftstoffilters 10 verbunden ist, welcher seinerseits im oberen Bereich des Gehäuses 6 untergebracht ist. Vom Kraftstoffilter 10 führt eine Kraftstoffleitung 11 durch einen als Teil des Gehäuses 6 ausgebildetes, die Tanköffnung verschließendes Deckelteil 12 nach außen.The module 5 has an essentially columnar, tubular housing 6 with a larger window in the housing peripheral wall. In the lower part of the housing 6 , a fuel pump 7 is arranged with a suction port 8 projecting downward from the housing 6 and a pressure regulator 9 connected to the pressure side of the pump 7 , combined with the pump, via which the fuel pump 7 with the input of a fuel filter 10 is connected, which in turn is housed in the upper region of the housing 6 . A fuel line 11 leads from the fuel filter 10 through a cover part 12 , which is formed as part of the housing 6 and closes the tank opening.

Am Deckelteil 12 sind von außen zugängliche elektrische Anschlüsse 13 angeordnet, die über nicht dargestellte elektrische Leitungen mit dem Elektroantrieb der Kraft­ stoffpumpe 7 bzw. mit Signalanschlüssen eines im Gehäuse 6 angeordneten Füllstandsgebers 14 des Kraftstofftanks 1 verbunden sind.On the cover part 12 , externally accessible electrical connections 13 are arranged, which are connected via electrical lines (not shown) to the electric drive of the fuel pump 7 or to signal connections of a level sensor 14 arranged in the housing 6 of the fuel tank 1 .

Im übrigen sind am Deckelteil 12 noch eine Entlüftungs­ anordnung 15 sowie vorzugsweise auch ein Drucksensor 16 angeordnet, mit dem gegebenenfalls die Dichtigkeit des Tanksystems überprüft werden kann, indem dasselbe unter einen gewissen Überdruck gesetzt wird.Otherwise, a venting arrangement 15 and preferably also a pressure sensor 16 are arranged on the cover part 12 , with which the tightness of the tank system can be checked if necessary, by placing the same under a certain excess pressure.

Oberhalb des Deckelteiles 12 kann auf der Tankaußenseite noch eine Schutzabdeckung 17 angeordnet sein.A protective cover 17 can also be arranged above the cover part 12 on the outside of the tank.

Abweichend von der dargestellten Ausführungsform kann der Schlingertopf 2 gegebenenfalls auch am Gehäuse 6 des Moduls 5 angeordnet bzw. mit dem Gehäuse 6 einstückig verbunden sein.Deviating from the illustrated embodiment, the swirl pot 2 can optionally also be arranged on the housing 6 of the module 5 or connected to the housing 6 in one piece.

Der dargestellte Modul 5 kann in praktisch identischer Form für beliebige Kraftstofftanks 1 verwendet werden. Im wesentlichen muß lediglich die vertikale Länge des Gehäuses 6 an den jeweiligen Tank 1 angepaßt sein, um zu gewährleisten, daß der Sauganschluß 8 der Kraftstoff­ pumpe 7 möglichst weit unten im Tank 1 angeordnet ist.The module 5 shown can be used in virtually identical form for any fuel tanks 1 . In essence, only the vertical length of the housing 6 must be adapted to the respective tank 1 to ensure that the suction port 8 of the fuel pump 7 is arranged as far down in the tank 1 .

Soweit erforderlich, kann im Modul 5 - beispielsweise integriert in den Kraftstoffilter 10 - eine Kraftstoff­ heizung vorgesehen sein, die elektrisch mit den An­ schlüssen 13 verbunden sein kann.If necessary, a fuel heater can be provided in the module 5 - for example integrated in the fuel filter 10 - which can be electrically connected to the connections 13 .

Üblicherweise fördert die Kraftstoffpumpe 7 mehr Kraft­ stoff, als vom Fahrzeugmotor benötigt wird. Der über­ schüssige geförderte Kraftstoff kann direkt auf der Druckseite der Pumpe 7, beispielsweise aus einem ent­ sprechenden Auslaß des Druckreglers 9, in den Schlinger­ topf 2 zurückgeführt werden. Damit erübrigt sich eine gesonderte, zwischen Motor und Tank 1 anzuordnende Rück­ laufleitung. Im übrigen wird bei dieser Bauart auch eine grundsätzlich unerwünschte Aufheizung des überschüssigen Kraftstoffes durch den Motor vermieden.Usually, the fuel pump 7 promotes more fuel than is required by the vehicle engine. The excess fuel delivered can be returned directly on the pressure side of the pump 7 , for example from a corresponding outlet of the pressure regulator 9 , in the Schlinger pot 2 . This eliminates the need for a separate return line to be arranged between the engine and tank 1 . In addition, a basically undesirable heating of the excess fuel by the engine is avoided with this type of construction.
