Zwei Ausführungsbeispiele der Erfindung sind in der Zeichnung dargestellt und in der nachfolgenden Beschreibung näher erläutert. Es zeigen Figur 1 ausschnittsweise eine Kraftstoffördereinrichtung, Figur 2 in vergrößerter Darstellung ein auf einem Stutzen angeordnetes, als Kraftstoffleitung dienendes Rohr der Kraftstoffördereinrichtung gemäß einem ersten Ausführungbeispiel, Figur 3 den Stutzen mit auf diesem angeordnetem abgetrenntem Rohr und befestigter neuer Kraftstoffleitung und Figur 4 das Rohr gemäß einem zweiten Ausführungsbeispiel.Two embodiments of the invention are in the Drawing shown and in the description below explained in more detail. 1 shows a section of a Fuel delivery device, Figure 2 in enlarged Representation of a arranged on a neck as Fuel pipe serving the Fuel delivery device according to a first Design example, Figure 3 with the nozzle on this arranged separated pipe and fastened new Fuel line and Figure 4 shows the pipe according to a second Embodiment.
Eine in Figur 1 vereinfacht dargestellte
Kraftstoffördereinrichtung für Kraftfahrzeuge weist ein
Kraftstofförderaggregat 10 auf, das Kraftstoff aus einem
Vorratsbehälter 12 zur Brennkraftmaschine 14 des
Kraftfahrzeugs fördert. Das Kraftstofförderaggregat 10 ist
über eine Kraftstoffleitung 16 mit der Brennkraftmaschine 14
verbunden, die an einem Stutzen 20 des
Kraftstofförderaggregats 10 befestigt ist. Zur
Kraftstoffördereinrichtung kann außerdem beispielweise auch
ein Rücklauf von der Brennkraftmaschine 14 in den
Vorratsbehälter 12 gehören, durch den überschüssiger, von
der Brennkraftmaschine nicht verbrauchter Kraftstoff in den
Vorratsbehälter 12 zurückgeführt wird und der ebenfalls eine
Kraftstoffleitung 22 umfaßt, die an einem Stutzen 24 an der
Brennkraftmaschine 14 und/oder am Vorratsbehälter 12
befestigt ist. Zur Kraftstoffördereinrichtung kann außerdem
ein Flansch 26 gehören, durch den eine Öffnung 28 im
Vorratsbehälter 12 verschließbar ist und der Stutzen 30
aufweist, auf denen innerhalb und außerhalb des
Vorratsbehälters 12 angeordnete Abschnitte der
Kraftstoffleitungen 16 und/oder 22 befestigt sind. Zur
Kraftstoffördereinrichtung können außerdem weitere Bauteile
gehören, an denen ebenfalls an einem Stutzen eine
Kraftstoffleitung befestigt ist.One shown in simplified form in FIG
Fuel delivery device for motor vehicles has
Nachfolgend wird beispielhaft die Ausbildung der am Stutzen
20 des Kraftstofförderaggregats 10 befestigten
Kraftstoffleitung 16 beschrieben, die in gleicher Weise für
alle weiteren Kraftstoffleitungen der
Kraftstoffördereinrichtung anwendbar ist. Die
Kraftstoffleitung 16 ist als Rohr ausgebildet und kann aus
steifem Kunststoff bestehen. Das Rohr 16 kann zumindest
abschnittsweise wellenförmig in Form eines sogenannten
Wellrohrs ausgebildet sein, so daß es in seinem Verlauf
flexibel an die jeweiligen Einbauverhältnisse angepaßt
werden kann. Der Stutzen 20 weist an seinem Außenumfang
wenigstens einen Kragen 34 auf; vorzugsweise sind mehrere in
Längsrichtung zueinander vesetzte Kragen 34 vorgesehen. Die
Kragen 34 sind an ihren zum freien Ende des Stutzens 20
weisenden Seiten angeschrägt, um ein leichtes Aufschieben
des Rohrs 16 zu ermöglichen, und mit ihren
gegenüberliegenden Seiten etwa senkrecht zur
Längserstreckung des Stutzens 20 angeordnet. Der Stutzen 20
weist somit eine tannenbaumähnliche Form auf, dessen Spitze
zum freien Ende des Stutzens 20 weist. Zu seiner Befestigung
am Stutzen 20 kann das Rohr 16 in seinem Endbereich erwärmt
werden, so daß es sich erweitert und auf den Stutzen 20 über
die Kragen 34 geschoben werden kann. Bei der Abkühlung
schrumpft das Rohr 16 wieder, wobei die Kragen 34 sich in
dieses einkrallen und somit das Rohr 16 auf dem Stutzen 20
halten, so daß dieses nicht mehr abgezogen werden kann.
Alternativ kann das Rohr 16 auch ohne Erwärmung montiert
werden, wobei dessen Ende unter entsprechender
Kraftaufwendung auf den Stutzen 20 aufgeschoben wird. Im
maximalen Pressungsbereich setzt sich das Kunststoffmaterial
des Rohrs 16, so daß sich dieses auf dem Tannenbaumprofil
des Stutzens 20 verkrallt und somit das Rohr 16 gegen
Abziehen sichert.The following is an example of the training of the
Das Rohr 16 weist bei einem in den Figuren 2 und 3
dargestellten ersten Ausführungsbeispiel nahe dem Stutzen 20
in einem über den Stutzen 20 hinausragenden Bereich an
seinem Außenumfang einen nach außen ragenden Anlagewulst 36
auf. Der Anlagewulst 36 kann vorteilhafterweise durch einen
Wellenabschnitt des Rohrs 16 gebildet sein, von denen
mehrere aneinandergereiht wie vorstehend beschrieben einen
Abschnitt des Rohrs 16 in Form eines Wellrohrs bilden, das
flexibel verbiegbar ist. Wenn ein Ausbau des Rohrs 16 oder
des Kraftstofförderaggregats 10 erforderlich ist, so kann
das Rohr 16 so abgetrennt werden, daß von diesem wie in
Figur 3 dargestellt ein Reststück 16a mit dem Anlagewulst 36
auf dem Stutzen 20 verbleibt. Das Reststück 16a des Rohrs 16
bildet dann einen neuen Stutzen, auf dem eine neue
Kraftstoffleitung 23 in Form eines flexiblen Schlauchs
befestigbar ist. Vorzugsweise wird das Rohr 16 direkt nach
dem Anlagewulst 36 abgetrennt, so daß das freie Ende des
verbleibenden Reststücks 16a sich etwa konisch verjüngt,
wodurch das nachfolgende Aufschieben des Schlauchs 23
erleichtert ist. Da der Anlagewulst 36 über den Stutzen 20
hinausragt ist sichergestellt, daß beim Abtrennen des Rohrs
16 der Stutzen 20 nicht teilweise mit abgetrennt wird. Der
Anlagewulst 36 verhindert ein Abrutschen des Schlauchs 23,
der gegebenenfalls zusätzlich auf dem auf dem Stutzen 20
angeordneten Reststück 16a mittels einer Schlauchklemme 38
gesichert werden kann. Das auf dem Stutzen 20 verbleibende
Reststück 16a des Rohrs 16 ist außerhalb des Anlagewulstes
36 an seinem Außenumfang glatt ausgebildet, das heißt, daß
die Kragen 34 nicht durch dieses hindurchdrücken, so daß die
Verbindung des Schlauchs 23 mit dem neuen Stutzen
dauerhaltbar ist.The
In Figur 4 ist das Rohr 16 gemäß einem zweiten
Ausführungsbeispiel dargestellt, bei dem der Anlagewulst 36
auf dem auf dem Stutzen 20 angeordneten Bereich des Rohrs 16
angeordnet ist. Das Rohr 16 kann dabei in seinem über den
Stutzen 20 hinausragenden Bereich eine Markierung 40
aufweisen, beispielsweise in Form einer Einkerbung, an der
das Abtrennen des Rohrs 16 erfolgen sollte, ohne daß ein
Teil des Stutzens 20 mit abgetrennt wird. Der Anlagewulst 36
kann dabei etwa auf derselben Höhe enden wie der Stutzen 20
oder bereits auf dem Stutzen 20 enden, so daß auch ein
glatter Abschnitt des Reststücks 16a des Rohrs 16 nach
dessen Abtrennen auf dem Stutzen 20 verbleibt.In Figure 4, the
