Definitions
- the invention relates to a fuel delivery device for Motor vehicles according to the preamble of claim 1.
- Such a fuel delivery device is by EP 0 562 536 A1 is known.
- This fuel delivery device has at least one fuel line designed as a pipe, through the components of the fuel delivery system or connected to the internal combustion engine of the motor vehicle are.
- the fuel line is on the components of the Fuel delivery device or the internal combustion engine on one Attachable nozzle, at least one on its outer circumference Has collar.
- the fuel line is on the nozzle a holding element fixed.
- the fuel delivery device with the features according to claim 1 has the advantage that the Fuel line to allow easy removal of Components of the fuel delivery system or the fuel line is prepared.
- the fuel line needs it not to be pulled off the nozzle and on the easy Way new spigot is a new fuel line, attachable for example in the form of a flexible hose.
- FIG. 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
- Figure 4 shows the pipe according to a second Embodiment.
- Fuel delivery device for motor vehicles has Fuel delivery unit 10, the fuel from a Reservoir 12 to the internal combustion engine 14 des Motor vehicle promotes.
- the fuel delivery unit 10 is via a fuel line 16 to the internal combustion engine 14 connected to a nozzle 20 of the Fuel delivery unit 10 is attached.
- Fuel delivery device can also, for example, also a return from the internal combustion engine 14 in the Reservoir 12 belong, by the excess, of the fuel in the internal combustion engine is not used
- Storage container 12 is returned and also one Fuel line 22 includes, which is connected to a nozzle 24 on the Internal combustion engine 14 and / or on reservoir 12 is attached.
- To the fuel delivery device can also include a flange 26 through which an opening 28 in Storage container 12 is closable and the nozzle 30 on which inside and outside the Reservoir 12 arranged sections of the Fuel lines 16 and / or 22 are attached.
- a flange 26 through which an opening 28 in Storage container 12 is closable and the nozzle 30 on which inside and outside the Reservoir 12 arranged sections of the Fuel lines 16 and / or 22 are attached.
- Fuel delivery device can also other components belong to which also on a nozzle one Fuel line is attached.
- the Fuel line 16 is designed as a tube and can be made of rigid plastic.
- the tube 16 can at least sectionally wavy in the form of a so-called Corrugated tube to be formed so that it is in its course flexibly adapted to the respective installation conditions can be.
- the nozzle 20 has on its outer circumference at least one collar 34; preferably several are in Collars 34 offset in the longitudinal direction are provided.
- the Collars 34 are at their free ends of the neck 20th bevelled sides to be easily pushed open to allow the tube 16, and with their opposite sides approximately perpendicular to Longitudinal extension of the nozzle 20 arranged.
- the nozzle 20 thus has a fir tree-like shape, the top of which points to the free end of the nozzle 20.
- the tube 16 can be heated in its end region be so that it expands and over to the nozzle 20 the collar 34 can be pushed. When cooling the tube 16 shrinks again, with the collar 34 in claw this and thus the pipe 16 on the nozzle 20th hold so that this can no longer be removed.
- the tube 16 can also be mounted without heating be, the end of which under appropriate Force is pushed onto the nozzle 20. in the The maximum pressure range is set by the plastic material of the tube 16 so that this is on the fir tree profile of the connector 20 claws and thus the tube 16 against Pulling off secures.
- the tube 16 has one in FIGS. 2 and 3 illustrated first embodiment near the nozzle 20th in an area projecting beyond the connector 20 its outer circumference an outwardly projecting abutment bead 36 on.
- the contact bead 36 can advantageously by a Shaft section of the tube 16 may be formed, of which several lined up as described above one Form section of the tube 16 in the form of a corrugated tube, the is flexibly bendable. If an expansion of the pipe 16 or of the fuel delivery unit 10 is required, so the tube 16 are separated so that from this as in FIG. 3 shows a remaining piece 16a with the contact bead 36 remains on the nozzle 20.
- the remainder 16a of the tube 16 then forms a new nozzle on which a new one Fuel line 23 in the form of a flexible hose is attachable.
- the pipe 16 is directly after the bead 36 separated so that the free end of the remaining remaining piece 16a tapers approximately conically, whereby the subsequent pushing of the hose 23 is relieved. Since the abutment bead 36 over the nozzle 20th protrudes ensures that when disconnecting the tube 16 of the connector 20 is not partially separated.
- the Contact bead 36 prevents the hose 23 from slipping, which, if necessary, additionally on the on the nozzle 20th arranged residual piece 16a by means of a hose clamp 38 can be secured.
- the remaining on the nozzle 20 Remaining piece 16a of the tube 16 is outside the abutment bead 36 formed smooth on its outer circumference, that is, the collar 34 do not push through this, so that the Connection of hose 23 to the new connector is durable.
- the tube 16 is according to a second Embodiment shown in which the abutment bead 36th on the area of the pipe 16 arranged on the connecting piece 20 is arranged.
- the tube 16 can be in his on the Stub 20 projecting area a mark 40 have, for example in the form of a notch on the the separation of the tube 16 should be done without a Part of the connector 20 is separated with.
- the contact bead 36 can end at approximately the same height as the nozzle 20 or already end on the nozzle 20, so that a smooth portion of the remaining piece 16a of the tube 16 after its separation remains on the nozzle 20.
