Anschlussconnection

Die Erfindung betrifft einen Anschluss für eine zu einer Brennkraftmaschine eines Kraftfahrzeuges führenden Vorlaufleitung an einer Kraftstoff aus einem Kraftstoffbehälter fördernden Förderpumpe mit einer mit der Förderpumpe verbundenen Aufnahme und mit einem mit der Aufnahme formschlüssig verbindbaren, eine Abwinklung aufweisenden Anschlussstutzen.The invention relates to a connection for a flow line leading to an internal combustion engine of a motor vehicle on a feed pump delivering fuel from a fuel tank with a receptacle connected to the feed pump and with a connection piece which has a bend and can be connected to the receptacle in a form-fitting manner.

Solche Anschlüsse werden in der Regel zur Verbindung der innerhalb eines Kraftstoffbehälters angeordneten Förderpumpe mit einem innerhalb des Kraftstoffbehälters verlaufenden Teilstück der Vorlaufleitung eingesetzt und sind aus der Praxis bekannt. Der Anschlussstutzen weist dabei einen umlaufenden Vorsprung auf. Ein Rastmittel hintergreift den Vorsprung und hält diesen an der Aufnahme.Such connections are generally used to connect the feed pump arranged inside a fuel tank to a section of the feed line running inside the fuel tank and are known from practice. The connecting piece has a circumferential projection. A locking means engages behind the projection and holds it on the receptacle.

Nachteilig bei dem bekannten Anschluss ist, dass Bewegungen der die an dem Anschlussstutzen angeschlossenen, in der Regel flexibel gestalteten Vorlaufleitung zu Undichtigkeiten des Anschlusses führen können.A disadvantage of the known connection is that movements of the supply line, which is generally flexible in design and which is connected to the connecting piece, can lead to leaks in the connection.

Der Erfindung liegt das Problem zugrunde, einen Anschluss der eingangs genannten Art so zu gestalten, dass er besonders zuverlässige Dichtheit aufweist.The invention is based on the problem of designing a connection of the type mentioned at the outset in such a way that it has particularly reliable tightness.

Dieses Problem wird erfindungsgemäß dadurch gelöst, dass der Anschlussstutzen in verschiedenen Winkelstellungen in der Aufnahme drehfest arretierbar ist.This problem is solved according to the invention in that the connecting piece can be locked in a rotationally fixed manner in the receptacle in different angular positions.

Durch diese Gestaltung ist der Anschlussstutzen zuverlässig mit der Aufnahme verbunden. Bewegungen der an dem An- schlussstutzen angeschlossenen Vorlaufleitung werden dank der Erfindung abgestützt und können daher nach der Montage des Anschlussstutzens in der Aufnahme nicht mehr zu Undichtigkeiten führen. Der erfindungsgemäße Anschluss hat daher eine besonders zuverlässige und während der Betriebsdauer der Förderpumpe dauerhafte Dichtheit .With this design, the connecting piece is reliably connected to the receptacle. Movements of the on the The connecting pipe connected to the supply pipe is supported thanks to the invention and can therefore no longer lead to leaks in the receptacle after installation of the connecting pipe. The connection according to the invention therefore has a particularly reliable tightness that is permanent during the operating life of the feed pump.

Die drehfeste Arretierung des Anschlussstutzens gestaltet sich gemäß einer vorteilhaften Weiterbildung der Erfindung konstruktiv besonders einfach, wenn der Anschlussstutzen einen formschlüssig mit der Aufnahme verbindbaren Mehrkant hat .According to an advantageous development of the invention, the non-rotatable locking of the connection piece is structurally particularly simple if the connection piece has a polygon that can be positively connected to the receptacle.

Die Versorgung einer zur Förderung von Kraftstoff innerhalb des Kraftstoffbehälters vorgesehenen Saugstrahlpumpe mit Kraftstoff als Treibmittel erfordert gemäß einer anderen vorteilhaften Weiterbildung der Erfindung einen besonders geringen baulichen Aufwand, wenn der Stutzen zwei Abgänge aufweist. Mit dem zweiten Abgang lässt sich beispielsweise eine Saugstrahlpumpe zur Förderung von Kraftstoff innerhalb des Kraf stoffbehälters antreiben.According to another advantageous development of the invention, the supply of a suction jet pump provided for the delivery of fuel within the fuel tank with fuel as a propellant requires a particularly low construction effort if the connecting piece has two outlets. With the second outlet, for example, a suction jet pump can be driven to deliver fuel within the fuel tank.

Der erfindungsgemäße Anschluss erfordert besonders wenige zu montierende Bauteile, wenn ein die Aufnahme aufweisender Gehäusedeckel der Fδrderpumpe einen Rasthaken zur Halterung des Anschlussstutzens hat.The connection according to the invention requires particularly few components to be assembled if a housing cover of the feed pump which has the receptacle has a latching hook for holding the connection piece.

Der Anschlussstutzen lässt sich gemäß einer anderen vorteilhaften Weiterbildung der Erfindung besonders einfach in der Aufnahme montieren und demontieren, wenn ein Rast- mittel lösbar mit der Aufnahme und dem Anschlussstutzen verbunden ist. Diese Gestaltung ermöglicht zudem einen einfachen Anschluss eines Prüfadapters an der Förderpumpe vor der Montage der Vorlaufleitung.According to another advantageous development of the invention, the connecting piece can be mounted and dismantled particularly easily in the receptacle if a locking means is detachably connected to the receptacle and the connecting piece. This design also enables a test adapter to be easily connected to the feed pump before the flow line is installed.

Der Anschlussstutzen gestaltet sich gemäß einer anderen vorteilhaften Weiterbildung der Erfindung konstruktiv be- sonders einfach, wenn ein in die Aufnahme eindringender Zapfen des Anschlussstutzens eine Rastausnehmung hat und wenn der Rasthaken oder das Rastmittel in die Rastausnehmung eindringt. Es ist aber auch denkbar, Rasthaken oder Rastmittel am Anschlussstutzen anzuordnen, die ihrerseits in Rastausnehmungen eindringen, die sich an der Förderpumpe befinden. Diese Rastausnehmungen können sowohl als umlaufende Nut oder als einzelne Ausnehmungen ausgebildet sein. Die Verwendung von einzelnen Ausnehmungen hat gegenüber einer umlaufenden Nut den Vorteil, dass die zu verbindenden Teile gleichzeitig zueinander drehfest arretiert werden.According to another advantageous development of the invention, the connecting piece is structurally particularly simple if a pin of the connecting piece penetrating into the receptacle has a latching recess and if the latching hook or the latching means penetrates into the latching recess. However, it is also conceivable to arrange latching hooks or latching means on the connecting piece, which in turn penetrate into latching recesses which are located on the feed pump. These locking recesses can be designed as a circumferential groove or as individual recesses. The use of individual recesses has the advantage over a circumferential groove that the parts to be connected are simultaneously locked in a rotationally fixed manner.

Eine Biegebeanspruchung des Rastmittels lässt sich gemäß einer anderen vorteilhaften Weiterbildung der Erfindung einfach vermeiden, wenn die Aufnahme in ihrem den Zapfen umschließenden Bereich eine Rastausnehmung hat und wenn das Rastmittel die Aufnahme im Bereich der Rastausnehmung durchdringt und in die Rastausnehmung des Zapfens eindringt .According to another advantageous development of the invention, bending stress of the latching means can be easily avoided if the receptacle has a latching recess in its area surrounding the pin and if the latching means penetrates the receptacle in the area of the latching recess and penetrates into the latching recess of the pin.

Die Montage des erfindungsgemäßen Anschlusses gestaltet sich besonders einfach, wenn das Rastmittel bügeiförmig gestaltet ist.The assembly of the connection according to the invention is particularly simple if the locking means is designed in the shape of a bow.

Ein Kippen des Anschlussstutzens gegenüber der Aufnahme lässt sich gemäß einer anderen vorteilhaften Weiterbildung der Erfindung einfach vermeiden, wenn die Aufnahme zwei einander gegenüberliegend angeordnete Rastausnehmungen hat .According to another advantageous development of the invention, tilting of the connecting piece relative to the receptacle can be avoided simply if the receptacle has two latching recesses arranged opposite one another.

Der erfindungsgemäße Anschluss lässt sich besonders kostengünstig fertigen, wenn das Rastmittel aus Kunststoff im Spritzgussverfahren gefertigt ist. 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 connection according to the invention can be manufactured particularly inexpensively if the locking means is made of plastic by injection molding. The invention permits numerous embodiments. To further clarify its basic principle, two of them are shown in the drawing and are described below. This shows in

Figur 1 zeigt eine Förderpumpe eines Kraftfahrzeuges mit einem Gehäuse 1 und mit einem Gehäusedeckel 2. Der Gehäusedeckel 2 trägt einen Anschluss 3 mit einer daran angeschlossenen Vorlaufleitung 4. Die Vorlaufleitung 4 ist in der Zeichnung geschnitten dargestellt und führt beispielsweise zu einem nicht dargestellten Flansch eines Kraftstoffbehälters des Kraftfahrzeuges. Die Förderpumpe saugt über einen dem Gehäusedeckel 2 gegenüberliegend angeordneten Ansaugstutzen 5 Kraftstoff an und fördert diesen zu dem Anschluss 3. Der Anschluss 3 hat einen Anschlussstutzen 7, welcher in der im Gehäusedeckel 2 angeordneten Aufnahme 6 befestigt ist. Der Anschlussstutzen 7 ist winklig gestaltet und ragt mit einem Zapfen 8 in die Aufnahme 6 hinein. Im Bereich des Zapfens 8 ist der Anschlussstutzen 7 mittels eines lösbaren Rastmittels 9 formschlüssig mit der Aufnahme 6 verbunden.FIG. 1 shows a feed pump of a motor vehicle with a housing 1 and with a housing cover 2. The housing cover 2 has a connection 3 with a flow line 4 connected to it. The flow line 4 is shown in section in the drawing and leads, for example, to a flange, not shown, of a fuel tank of the motor vehicle. The feed pump sucks fuel through a suction port 5 arranged opposite the housing cover 2 and conveys this to the connection 3. The connection 3 has a connection connection 7 which is fastened in the receptacle 6 arranged in the housing cover 2. The connecting piece 7 is angular and projects into the receptacle 6 with a pin 8. In the area of the pin 8, the connecting piece 7 is positively connected to the receptacle 6 by means of a releasable locking means 9.

Figur 2 zeigt den Anschluss 3 aus Figur 1 vergrößert in einem Längsschnitt entlang der Linie II - II. Der Zapfen 8 hat einen Mehrkant 10, mit dem er in die entsprechend gestaltete Aufnahme 6 eingesetzt ist. Der Zapfen 8 und damit der in Figur 1 dargestellte Anschlussstutzen 7 lässt sich hierdurch in verschiedenen WinkelStellungen gegenüber der Aufnahme 6 drehfest arretieren. Die Aufnahme 6 hat hier einen wie den Mehrkant 10 des Zapfens 8 gestalteten Innenmehrkant 11. Selbstverständlich kann die Aufnahme 6 auch eine feine Rasterung aufweisen, mit der sie die Kanten des Mehrkantes 10 des Zapfens 8 seitlich umgreift. Das Rastmittel 9 stützt sich mit einem Vorsprung 12 an der Außenseite der Aufnahme 6 ab.Figure 2 shows the connection 3 of Figure 1 enlarged in a longitudinal section along the line II - II. The pin 8 has a polygon 10 with which it is inserted into the correspondingly designed receptacle 6. The pin 8 and thus the connection piece 7 shown in FIG. 1 can thereby be locked in a rotationally fixed manner in different angular positions relative to the receptacle 6. The receptacle 6 here has an inner polygon 11 designed like the polygon 10 of the pin 8. Of course, the receptacle 6 can also have a fine grid with which it laterally engages around the edges of the polygon 10 of the pin 8. The locking means 9 is supported with a projection 12 on the outside of the receptacle 6.

Figur 3 zeigt durch den Anschluss 3 aus Figur 1 in einer vergrößerten Schnittdarstellung entlang der Linie III - III. Der Zapfen 8 des Anschlussstutzens 7 hat eine Nut 13 zur Aufnahme eines O-Rings 14. Der O-Ring 14 ist gegen die Wandung der Aufnahme 6 vorgespannt und dichtet den Zapfen 8 ab. Weiterhin zeigt Figur 3, dass die Aufnahme 6 zwei einander gegenüberstehende Rastausnehmungen 15a, 15b aufweist. Der Zapfen 8 hat eine als umlaufende Nut ausgebildete Rastausnehmung 16. Das Rastmittel 9 weist in die Rastausnehmungen 15a, 15b, 16 eingreifende Rastarme 17a, 17b auf.Figure 3 shows through the connection 3 of Figure 1 in an enlarged sectional view along the line III - III. The pin 8 of the connecting piece 7 has a groove 13 for receiving an O-ring 14. The O-ring 14 is biased against the wall of the receptacle 6 and seals the pin 8. FIG. 3 further shows that the receptacle 6 has two opposing locking recesses 15a, 15b. The pin 8 has a locking recess 16 designed as a circumferential groove. The locking means 9 has locking arms 17a, 17b which engage in the locking recesses 15a, 15b, 16.

Figur 4 zeigt einen Anschluss 18 im Längsschnitt. Dieser Anschluss 18 unterscheidet sich von dem aus Figur 3 vor allem dadurch, dass an dem Gehäusedeckel 2 im Bereich der Aufnahme 6 ein Rasthaken 19 angeordnet ist. Ein Zapfen 20 des Anschlussstutzens 22 hat eine als umlaufende Nut ausgebildete Rastausnehmung 21. Der Rasthaken 19 dringt im dargestellten montierten Zustand des Anschlusses 18 in die Rastausnehmung 21 ein und hält den Anschlussstutzen 21 in seiner Lage. Weiterhin hat der Anschlussstutzen 21 zwei Abgänge 23, 24, von denen einer zum Anschluss der in Figur 1 dargestellten Vorlaufleitung 4 dient . An dem anderem Abgang 23, 24 lässt sich beispielsweise eine nicht dargestellte, zum Fördern von Kraftstoff innerhalb des Kraftstoffbehälters vorgesehene Saugstrahlpumpe anschließen. Figure 4 shows a connection 18 in longitudinal section. This connection 18 differs from that from FIG. 3 primarily in that a latching hook 19 is arranged on the housing cover 2 in the region of the receptacle 6. A pin 20 of the connecting piece 22 has a latching recess 21 designed as a circumferential groove. The latching hook 19 penetrates into the latching recess 21 in the illustrated assembled state of the connector 18 and holds the connecting socket 21 in its position. Furthermore, the connecting piece 21 has two outlets 23, 24, one of which is used to connect the flow line 4 shown in FIG. 1. For example, one cannot be connected to the other outlet 23, 24 Connect the suction jet pump shown to deliver fuel within the fuel tank.
