Fördereinheitdelivery unit
Gegenstand der Erfindung ist eine Fördereinheit mit einem Schwalltopf, einer in dem Schwalltopf angeordneten Kraft¬ stoffpumpe und einem Pumpenhalter, wobei die Kraftstoffpumpe im Pumpenhalter angeordnet ist und der Pumpenhalter im Schwalltopf befestigt ist. Derartige Fördereinheiten werden zum Fördern von Kraftstoff aus dem Kraftstoffbehälter einesThe invention relates to a conveyor unit with a swirl pot, arranged in the swirl pot fuel pump ¬ and a pump holder, wherein the fuel pump is arranged in the pump holder and the pump holder is mounted in the swirl pot. Such delivery units are used to deliver fuel from the fuel tank of a
Kraftfahrzeugs zu einer Brennkraftmaschine des Kraftfahrzeugs verwendet .Motor vehicle used to an internal combustion engine of the motor vehicle.
Fördereinheiten der eingangs genannten Art sind seit langem bekannter Stand der Technik. Der Pumpenhalter einer Fördereinheit dient dabei einerseits der ortsfesten Anordnung der Kraftstoffpumpe im Schwalltopf, andererseits hat er die Aufgabe von der Kraftstoffpumpe erzeugt Schwingungen zu dämp¬ fen, bzw. deren Übertragung auf den Schwalltopf zu verhin- dern. Auf diese Weise lassen sich ungewollte Geräusche redu¬ zieren. Insbesondere zur Schwingungsdämpfung der Kraftstoffpumpe sind zahlreiche Pumpenhalter bekannt, die eine erste Aufnahme zur Lagerung der Kraftstoffpumpe und eine zweite Aufnahme zur Befestigung des Pumpenhalters am Schwalltopf aufweisen. Die beiden Aufnahmen sind mit einem dazwischenliegenden Dämpfungselement verbunden, welches die Aufgabe hat, die Übertragung der Schwingungen von der ersten Aufnahme zur zweiten Aufnahme zu verhindern. Das Dämpfungselement ist in der Regel ein elastisches Teil, welches seine Elastizität durch die Werkstoffwahl, vorzugsweise Gummi, oder durch seine Gestaltung, vorzugsweise spiral- oder mäanderförmig, erhält. Nachteilig bei diesen Pumpenhaltern ist die relativ komplexe Formgestaltung, so dass deren Herstellung mit erheblich Kosten verbunden ist.Conveyor units of the type mentioned are known for a long time prior art. The pump holder of a conveyor unit serves on the one hand the fixed arrangement of the fuel pump in the surge pot, on the other hand, it has the function of the fuel pump generates vibrations to dämp ¬ fen, or countries whose transfer to the surge chamber to prevent. In this way, unwanted noise can be redu ¬ grace. In particular, for vibration damping of the fuel pump, numerous pump holders are known which have a first receptacle for mounting the fuel pump and a second receptacle for mounting the pump holder on the swirl pot. The two recordings are connected to an intermediate damping element, which has the task of preventing the transmission of the vibrations from the first receptacle to the second receptacle. The damping element is usually an elastic member, which receives its elasticity by the choice of material, preferably rubber, or by its design, preferably helical or meandering. A disadvantage of these pump holders is the relatively complex shape design, so that their production is associated with considerable costs.
Der vorliegenden Erfindung liegt daher die Aufgabe zugrunde, eine Fördereinheit zu schaffen, die einfach aufgebaut und daher kostengünstig ist . Die Fördereinheit soll darüber hin¬ aus für verschiedene Pumpentypen geeignet sein.The present invention is therefore an object of the invention to provide a conveyor unit, which is simple and therefore it is inexpensive. The delivery unit will also be out ¬ suitable for various types of pumps.
Erfindungsgemäß wird die Aufgabe dadurch gelöst, dass der Pumpenhalter mindestens zwei Stäbe aufweist, die im Schwall¬ topf befestigt sind, und dass die Stäbe mit einer Aufnahme für die Kraftstoffpumpe verbunden sind.According to the invention, the object is achieved in that the pump holder has at least two rods which are attached pot in the surge ¬ , and that the rods are connected to a receptacle for the fuel pump.
Die Fördereinheit zeichnet sich mit der Verwendung der Stäbe im Pumpenhalter durch einen sehr einfachen Aufbau aus. Dadurch ist der Pumpenhalter leicht herstellbar, wodurch die Fördereinheit kostengünstiger ist. Darüber hinaus wurde mit der Verwendung von Stäben im Pumpenhalter Elemente gefunden, welche aufgrund ihrer Struktur einerseits eine ausreichende Festigkeit besitzen, um als Befestigungsmittel zu wirken und andererseits eine ausreichende Elastizität aufweisen, um Schwingungen zu dämpfen. Damit werden die von der Kraftstoffpumpe erzeugten Schwingungen wirksam vom Schwalltopf entkoppelt .The delivery unit is characterized by the use of the rods in the pump holder by a very simple structure. As a result, the pump holder is easy to produce, whereby the conveyor unit is cheaper. Moreover, with the use of rods in the pump holder, elements have been found which, on the one hand, due to their structure, on the one hand have sufficient strength to act as fastening means and, on the other hand, have sufficient elasticity to dampen vibrations. Thus, the vibrations generated by the fuel pump are effectively decoupled from the swirl pot.
Eine besonders gute Entkopplung des Schwalltopfes von den Schwingungen der Kraftstoffpumpe wird mit Stäben erreicht, die achsparallel zur axialen Erstreckung der Kraftstoffpumpe angeordnet sind und wobei die Länge der Stäbe zwischen der Aufnahme und dem Boden des Schwalltopfes in etwa der Länge der Kraftstoffpumpe entspricht. In diesen Fällen erstrecken sich die Stäbe vom Boden des Schwalltopfes bis in den Bereich des Anschlussstücks der Kraftstoffpumpe. Durch diese Anord¬ nung besitzen die Stäbe eine große Länge mit der eine beson- ders hohe Elastizität zur Schwingungsdämpfung erreicht wird.A particularly good decoupling of the baffle from the vibrations of the fuel pump is achieved with rods which are arranged axially parallel to the axial extent of the fuel pump and wherein the length of the rods between the receptacle and the bottom of the baffle corresponds approximately to the length of the fuel pump. In these cases, the rods extend from the bottom of the swirl pot into the area of the connection piece of the fuel pump. Through this Anord ¬ planning the bars have a large length of a Particularly high elasticity is achieved for vibration damping.
Bei relativ ruhig laufenden Kraftstoffpumpen, die aufgrund ihres Aufbaus zu weniger Schwingungen neigen, kann die Länge der Stäbe zwischen der Aufnahme und dem Boden des Schwalltop- fes reduziert werden, so dass die Kraftstoffpumpe nicht im Bereich des Anschlussstücks, sondern bezogen auf ihre axiale Erstreckung mittig gelagert wird. Eine besonders einfache Befestigung der Stäbe im Boden des Schwalltopfes wird mittels einer Steckverbindung, insbesonde¬ re über eine Presspassung, erreicht.In relatively quiet running fuel pumps, which tend due to their construction to less vibrations, the length of the rods between the receptacle and the bottom of the Schwalltop- fes can be reduced, so that the fuel pump not in the region of the connector, but in terms of their axial extent in the middle is stored. A particularly simple mounting of the rods in the bottom of the baffle, is achieved by means of a plug connection, insbesonde ¬ re via a press fit.
Eine besonders belastbare Verbindung zwischen den Stäben und dem Schwalltopf wird mit einer Stoffschlüssigen Verbindung, vorzugsweise mittels Schweißen, erreicht.A particularly strong connection between the rods and the swirl pot is achieved with a cohesive connection, preferably by welding.
Eine nachträgliche Montage der Stäbe im Schwalltopf wird ge¬ mäß einer anderen Ausgestaltung dadurch vermieden, dass die Stäbe einteilig am Boden des Schwalltopfes angeformt sind.Subsequent mounting of the rods in the surge pot is ge ¬ Mäss another embodiment avoided in that the rods are formed integrally at the bottom of the baffle.
Die Verbindung der Stäbe mit der Aufnahme erfolgt in einer weiteren Ausgestaltung in besonders einfacher Weise mittels einer Steckverbindung.The connection of the rods with the recording takes place in a further embodiment in a particularly simple manner by means of a plug connection.
Der Pumpenhalter ist dabei mit geringem Aufwand an verschie¬ dene Kraftstoffpumpen, insbesondere Pumpenlängen, anpassbar, wenn der Durchmesser der Stäbe, beginnend am dem Boden desThe pump holder is with little effort to verschie ¬ dene fuel pumps, especially pump lengths, adaptable when the diameter of the rods, starting at the bottom of the
Schwalltopfes abgewandten Ende, stufenweise oder kontinuier¬ lich zunimmt. Durch entsprechend gestaltete Durchmesser der Aufnahme lässt sich so die Aufnahme in gewünschten Höhen zu den Stäben anordnen. Der Vorteil hierbei besteht darin, dass die Stäbe nicht separat an die unterschiedlichen Kraftstoff¬ pumpen angepasst werden müssen. Vielmehr kann eine Stabgröße für alle Varianten Verwendung finden.Schwall pot end facing away, gradually or continuously ¬ increases. By appropriately shaped diameter of the recording can thus arrange the recording at desired heights to the bars. The advantage here is that the rods do not have to be adapted separately to the different fuel ¬ pump. Rather, a bar size can be used for all variants.
Eine Montage der Stäbe mit der Aufnahme lässt sich ebenso durch die einteilige Ausbildung der Stäbe mit der Aufnahme gemäß einer anderen Ausgestaltung vermeiden.An assembly of the rods with the recording can also be avoided by the one-piece design of the rods with the inclusion of another embodiment.
Die Aufnahme besitzt einen sehr einfachen Aufbau, wenn sie in axialer Erstreckung eine geringe Ausdehnung aufweist. Sofern die Stäbe bis in den Bereich des Anschlussstücks der Kraft¬ stoffpumpe ausgebildet sind, wird die Kraftstoffpumpe mit ei¬ ner derartigen Aufnahme im Bereich des Anschlussstücks gela- gert . Aufgrund der Gestaltung der Kraftstoffpumpe kann es je¬ doch erforderlich sein, die Kraftstoffpumpe in der Mitte oder am entgegengesetzten Ende im Bereich der Pumpstufe zu lagern. Um dennoch eine ausreichende Entkopplung des Schwalltopfes von den Schwingungen der Kraftstoffpumpe zu erreichen, hat es sich als vorteilhaft herausgestellt, eine topfförmige Aufnah¬ me und Stäbe ausreichender Länge zu verwenden. Mit dieser Gestaltung kann die Länge der Stäbe unverändert beibehalten werden. Die Anpassung des Pumpenhalters an den Lagerungspunkt der Kraftstoffpumpe in der Aufnahme wird nunmehr über die Länge der topfförmigen Ausgestaltung der Aufnahme erreicht.The recording has a very simple structure, if it has a small extent in the axial extent. Provided that the rods into the region of the connection piece of the force ¬ fuel pump are formed, the fuel pump is Gela with egg ¬ ner such recording in the area of the connection piece gert. Due to the design of the fuel pump can ever ¬ nevertheless be necessary to store the fuel pump in the middle or at the opposite end in the pump stage. In order to still achieve adequate decoupling of the surge chamber from the vibrations of the fuel pump, it has proven to be advantageous to have a cup-shaped Recordin ¬ me and use rods of sufficient length. With this configuration, the length of the bars can be kept unchanged. The adaptation of the pump holder to the storage point of the fuel pump in the receptacle is now achieved over the length of the pot-shaped configuration of the recording.

Die in Figur 1 dargestellte Fördereinheit besteht aus einem Schwalltopf 1 in dem eine Kraftstoffpumpe 2 angeordnet ist. Die Kraftstoffpumpe 2 ist in einem Pumpenhalter 3 gelagert und über diesen mit dem Boden 4 des Schwalltopfes 1 verbunden .The conveying unit shown in Figure 1 consists of a swirl pot 1 in which a fuel pump 2 is arranged. The fuel pump 2 is mounted in a pump holder 3 and connected via this with the bottom 4 of the swirl pot 1.
Der Pumpenhalter 3 besteht aus einer Aufnahme 5 und drei Stä- ben 6. Die Stäbe 6 sind in Ausnehmungen des Bodens 4 einge- presst, wobei sie einen Pumpenvorfilter 8 durchdringen. Die Stäbe 6 erstrecken sich achsparallel zur Kraftstoffpumpe 2 bis in Höhe des Anschlussstückes 7, wo sie mit ihren dem Bo¬ den 4 abgewandten Enden in Ausnehmungen der Aufnahme 5 einge- presst sind. Die Aufnahme 5 des Pumpenhalters 3 ist bezüglich ihrer axialen Erstreckung auf das Anschlussstück 7 der Kraftstoffpumpe 2 beschränkt . In dem in Figur 2 geschnitten dargestellten Schwalltopf 1 ist eine Kraftstoffpumpe 2 angeordnet. Die Kraftstoffpumpe 2 ist in der Aufnahme 5 eines Pumpenhalters 3 gelagert, wobei die Aufnahme 5 topfförmig ausgebildet ist, so dass sie nahezu die gesamte Kraftstoffpumpe 2 aufnimmt. Das obere Ende 9 der Auf¬ nahme 5 erstreckt sich bis in den Bereich des Anschlussstücks 7 der Kraftstoffpumpe 2. An dem oberen Ende 9 sind Verbin¬ dungsstellen 10 angeformt, in die die drei Stäbe 6 einge- presst sind. Mit ihrem anderen Ende sind die Stäbe 6 mit dem Boden 4 des Schwalltopfes 1 verbunden. Unterhalb der Aufnahme 5 ist ein Pumpenvorfilter 8 angeordnet, den die Stäbe 6 durchdringen. Die Stäbe 6 verlaufen somit achsparallel zur Kraftstoffpumpe 2. Aufgrund dessen dass die Stäbe 6 bis in den Bereich des Anschlussstücks 7 der Kraftstoffpumpe 2 ge¬ führt sind, besitzen sie mit ihrer Länge eine ausreichende Elastizität, um Schwingungen der Kraftstoffpumpe 2 wirksam gegenüber dem Schwalltopf 1 zu entkoppeln.The pump holder 3 consists of a receptacle 5 and three bars 6. The bars 6 are pressed into recesses in the bottom 4, wherein they penetrate a pump prefilter 8. The rods 6 extend axially parallel to the fuel pump 2 up to the height of the connecting piece 7, where they are pressed with their the Bo ¬ den 4 opposite ends in recesses of the receptacle 5. The receptacle 5 of the pump holder 3 is limited with respect to its axial extent to the connecting piece 7 of the fuel pump 2. In the swirl pot 1 shown cut in Figure 2, a fuel pump 2 is arranged. The fuel pump 2 is mounted in the receptacle 5 of a pump holder 3, wherein the receptacle 5 is cup-shaped, so that it receives almost the entire fuel pump 2. The upper end 9 of the up ¬ receiving 5 extends into the region of the connecting piece 7 of the fuel pump 2. At the upper end 9 connec ¬ tion points 10 are formed, in which the three rods 6 are pressed. With their other end, the rods 6 are connected to the bottom 4 of the swirl pot 1. Below the receptacle 5, a pump pre-filter 8 is arranged, penetrate the rods 6. The rods 6 extend thus axially parallel to the fuel pump 2. Because of this, that the bars 6 into the region of the connection piece 7 of the fuel pump 2 ge ¬ leads, they have with their length sufficient elasticity to oscillations of the fuel pump 2 effective against the swirl pot 1 to decouple.
Der in Figur 3 gezeigte Stab 6 eines Pumpenhalters 3 weist mehrere Bereiche 11 unterschiedlichen Durchmessers auf, wobei die Durchmesser der Bereiche 11 von oben nach unten stufenartig ansteigen. Die Übergänge zwischen zwei Bereichen 11 bilden Raststellen 12, in denen die Verbindungsstellen 10 gela- gert werden können. Durch entsprechende Ausbildung der Verbindungsstellen kann die Aufnahme 5 in verschiedenen Höhen zum Boden 4 des Schwalltopfes 1 angeordnet werden. Ein derart ausgebildeter Stab 6 eines Pumpenhalters 3 kann somit für verschiedene Einsatzmöglichkeiten verwendet werden. The rod 6 of a pump holder 3 shown in FIG. 3 has a plurality of regions 11 of different diameters, wherein the diameters of the regions 11 increase stepwise from top to bottom. The transitions between two regions 11 form latching points 12, in which the connection points 10 can be stored. By appropriate design of the joints, the receptacle 5 can be arranged at different heights to the bottom 4 of the swirl pot 1. Such a trained rod 6 of a pump holder 3 can thus be used for various applications.
