Definitions
- the invention is based on a fastening arrangement of a fuel line on a nozzle according to the preamble of claim 1.
- the fuel line is attached to a connection piece of a component of a fuel delivery device.
- Fuel lines can be designed as pipes made of plastic or as flexible hoses, pipes being less expensive than hoses.
- the connecting piece When using pipes, the connecting piece usually has a plurality of collars spaced from one another in the direction of its longitudinal axis and projecting from the outer circumference thereof and is designed in the manner of a fir tree profile.
- the pipe can be fastened on the connecting piece by pushing it in the direction of its longitudinal axis, the pulling of the pipe being prevented by the claws in the pipe and at the same time achieving a seal shall be.
- the socket can be opened even before the
- Fuel line can be arranged on this and expands elastically when pushed on, so that at the
- the socket is fixed in a simple manner in the direction of the longitudinal axis of the nozzle.
- FIG. 1 shows a nozzle and a fuel line to be fastened thereon
- FIG Fuel line in a cross section along line II-II in Figure 1 and Figure 3, the nozzle with the fuel line arranged thereon.
- FIGS. 1-10 A fastening arrangement of a fuel line on a nozzle shown in FIGS.
- Fuel delivery device can be provided, through which fuel is delivered from a storage tank to the internal combustion engine of a motor vehicle.
- the nozzle 10 can be arranged, for example, on a delivery unit 11 (not shown in more detail) or on any other components of the fuel delivery device.
- the connector 10 can consist of metal or preferably of fuel-resistant plastic.
- the connecting piece 10 has a plurality of collars 14 spaced apart from one another in the direction of its longitudinal axis 12 and projecting outward from its outer circumference.
- the collars 14 each have a bevel 16 towards the free end of the connector 10 and a shoulder 18 arranged approximately perpendicular to the longitudinal axis 12 on their opposite sides.
- the connector 10 thus has a so-called fir tree profile on its outer circumference. It can be provided that the collar 14a arranged closest to the free end of the connection piece 10 projects less from the outer circumference of the connection piece 10.
- the collar 14a is of less sharp-edged design, that is to say its shoulder 18a is beveled away from the free end of the connector 10 and / or the transition between the bevel 16a and the shoulder 18a is rounded.
- the nozzle 10 is chamfered at its free end to its longitudinal axis 12.
- the fuel line 20 is designed as a rigid tube made of fuel-resistant plastic.
- the pipe 20 can be designed in sections as a so-called corrugated pipe, in order to be able to adapt it flexibly in its course to the respective installation conditions.
- a bushing 22, which can be elastically expanded, is arranged on the end region of the tube 20 that can be pushed onto the socket 10.
- the elastic expandability of the bushing 22 can be achieved, for example, by means of a longitudinal slot 24 or by using a sufficiently elastically deformable material for the bushing 22, which can then be designed as a completely closed ring.
- the bushing 22 is thin-walled, that is to say that its thickness in the radial direction to the longitudinal axis 12 is smaller in relation to its width in the direction of the longitudinal axis 12.
- the socket 22 can consist of metal or plastic, in particular the socket 10 and the socket 22 can be made of the same plastic.
- the bushing 22 is fixed on the tube 20 in the direction of the longitudinal axis 12, that is to say cannot be displaced thereon.
- the tube 20 can have two elevations 26 which protrude outward from its outer circumference and are spaced apart in the direction of the longitudinal axis 12 approximately according to the width of the bushing 22.
- the bushing 22 can be slid from the end of the tube 22 over one of the elevations 26 with an elastic widening and is then arranged between the elevations 26 and fixed in the direction of the longitudinal axis 12.
- the tube 20 When the tube 20 is fastened on the nozzle 10, it is pushed onto the nozzle 10 in the direction of the longitudinal axis 12.
- the tube 20 is expanded and the collar 14 claw under plastic deformation of the tube 20 in its inner circumference.
- the socket 22 is at Sliding on the nozzle 10 extends elastically and is arranged in the end position of the tube 20 in the region of the collar 14a.
- the prestressed bushing 22 exerts a pressure on the tube 20 in the region of the collar 14a and thus achieves a secure seal, even if the tube 20 widens after being heated up considerably. If the connector 10 and the bushing 22 are made of the same plastic, they expand approximately the same amount when heated, so that essentially the same pressure remains as in the unheated state.
- the dimensions of the socket 22 are such that the tolerances and out-of-roundness of the connector 10 and the tube 20 are compensated for.
- the pull-off strength of the tube 20 is achieved by means of the further collars 14 clawing in the tube 20.
