Abstract
Description
Die vorliegende Erfindung betrifft eine Kraftstoffleitung gemäß dem Oberbegriff des Anspruchs 1.The The present invention relates to a fuel line according to the Preamble of claim 1.
In vielen technischen Bauteilen gibt es hydraulische Leitungen mit Wellrohranteilen, die sich aus sogenannten Wellentälern und Wellenbergen zusammensetzen. Im Betrieb werden die Leitungen dynamisch auf Druck belastet. Dadurch können sich die Wellrohranteile längen, weil die Wellenkontur „gerade gezogen” wird und nicht mehr formstabil ist. Hierdurch können technische Schwierigkeiten entstehen.In Many technical components are equipped with hydraulic lines Corrugated pipe components, which are made of so-called wave troughs and make wave mountains. In operation, the lines dynamically loaded on pressure. This allows the corrugated pipe components lengths, because the wave contour is "pulled straight" and is no longer dimensionally stable. This can be technical Difficulties arise.
Zur Zugentlastung wird im inneren der Wellrohrleitung eine Zugentlastung eingebracht, so dass die Leitungen formstabil bleiben und sich nicht längen können.to Strain relief is a strain relief inside the corrugated pipe introduced, so that the lines remain dimensionally stable and not can length.

Auch im Bereich der Kraftstoffleitungen kommen Wellrohrleitungen zum Einsatz. Gelängte Wellrohrleitungen können jedoch zu akustischen Funktionsstörungen führen.Also Corrugated pipes are used in the area of fuel lines Commitment. However, long corrugated pipes can lead to acoustic malfunctions.
Aufgabe der vorliegenden Erfindung ist es demnach, eine Kraftstoffleitung vorzuschlagen, die zumindest abschnittsweise als Wellrohrleitung ausgebildet ist, bei der jedoch keine unbeabsichtigte Längung auftreten kann.task Accordingly, it is the object of the present invention to provide a fuel line to propose, at least in sections, as a corrugated pipe is formed, but in which no unintentional elongation can occur.
Erfindungsgemäße wird diese Aufgabe dadurch gelöst, dass die Wellrohrleitung zumindest abschnittsweise mit einer Zugentlastung ausgestattet ist. Durch die Zugentlastung können bei bestehendem Design höheren Betriebsinnendrücke ohne zusätzliche Betriebslängung oder Design/Materialänderungen (zur Kostenreduzierung) bei gleicher Betriebslängung vorgenommen werden.invention This object is achieved in that the corrugated pipe at least partially equipped with a strain relief. Due to the strain relief can be higher with existing design Internal operating pressures without additional operating elongation or design / material changes (to reduce costs) be made at the same operating length.
Weitere vorteilhafte Ausgestaltungen der vorgeschlagenen Kraftstoffleitung ergeben sich aus den Merkmalen der Unteransprüche.Further advantageous embodiments of the proposed fuel line emerge from the features of the subclaims.
Weitere Merkmale und Vorteile der vorliegenden Erfindung werden deutlich anhand der nachfolgenden Beschreibung bevorzugter Ausführungsbeispiele unter Bezugnahme auf die beiliegenden Abbildungen.

Das

Dadurch
ist das Wellrohr
Wird das Fluidum, insbesondere der Kraftstoff, unter hohem Druck durch eine Kraftstoffleitung gemäß dem Stand der Technik geleitet, längt sich der Wellrohranteil. Der gewellte Bereich längt sich aufgrund der geringeren Wanddicke und unterschiedlicher Druckbeanspruchung. Wird der plastische Bereich des Leitungsmaterials dabei überschritten, ist die Längung dauerhaft. Dies kann zu erheblichen technischen Problemen führen, wie Leitungsanlage, Leitungsklappern oder Verhakung mit anderen Bauteilen.Becomes the fluid, in particular the fuel, under high pressure a fuel line according to the prior art passed, the corrugated pipe portion lengthens. The wavy area Lengthens due to the smaller wall thickness and different Compression. Will the plastic area of the pipe material exceeded, the elongation is permanent. This can lead to significant technical problems such as conduction, rattling or entanglement with others Components.
