Definitions
- the invention is based on a fuel line for fuel delivery devices of motor vehicles according to the preamble of claim 1.
- Such a fuel line is known from DE 42 24 981 AI.
- Components of the fuel delivery device are connected to one another or to the internal combustion engine of the motor vehicle through the fuel line.
- the fuel line can be fastened to the components of the fuel delivery device or the internal combustion engine on a connection piece.
- Fuel lines can generally be designed as a flexible hose or as a tube. Pipes are less expensive than fuel-resistant hoses, but they have the disadvantage that either expensive connection means are required to attach them to the connecting piece, or their direct attachment and solution to the connecting piece is only possible with special assembly or disassembly devices, so that a Removal of components of the fuel delivery device or the fuel line is not possible in a simple manner.
- the configuration of the fuel line according to the invention with the features according to claim 1 has the advantage that it is prepared to enable simple removal of components of the fuel delivery device or the fuel line.
- a new fuel line for example in the form of a flexible hose, can be attached to the new nozzle which can be produced in a simple manner.
- FIG. 1 shows a detail of a fuel delivery device
- FIG. 2 shows an enlarged view of a pipe of the fuel delivery device according to a first exemplary embodiment that is arranged on a connecting piece and serves as a fuel line
- FIG. 3 shows the connecting piece with a separate pipe arranged thereon and a new fuel line attached and a second embodiment.
- a fuel delivery device for motor vehicles shown in simplified form in FIG. 1, has a fuel delivery unit 10 which delivers fuel from a storage container 12 to the internal combustion engine 14 of the motor vehicle.
- the fuel delivery unit 10 is connected via a fuel line 16 to the internal combustion engine 14, which is fastened to a connecting piece 20 of the fuel delivery unit 10.
- the fuel delivery device may also include, for example, a return flow from the internal combustion engine 14 into the storage container 12, through which excess fuel not used by the internal combustion engine is returned to the storage container 12 and which likewise comprises a fuel line 22, which is connected to a connection piece 24 on the internal combustion engine 14 and / or is attached to the storage container 12.
- the fuel delivery device may also include a flange 26, through which an opening 28 in the storage container 12 can be closed and which has the connection piece 30, on which sections of the fuel lines 16 and / or 22 arranged inside and outside the storage container 12 are fastened.
- the fuel delivery device can also include other components to which a fuel line is also attached to a connecting piece.
- Fuel line 16 described, the same for all other fuel lines
- Fuel delivery device is applicable.
- Fuel line 16 is designed as a tube and can consist of rigid plastic.
- the tube 16 can be wave-shaped at least in sections in the form of a so-called
- Corrugated tube to be formed so that it is in its course can be flexibly adapted to the respective installation conditions.
- the nozzle 20 has at least one collar 34 on its outer circumference; preferably a plurality of collars 34 offset in the longitudinal direction are provided.
- the collars 34 are chamfered on their sides facing the free end of the socket 20 in order to enable the tube 16 to be easily pushed on, and are arranged with their opposite sides approximately perpendicular to the longitudinal extension of the socket 20.
- the nozzle 20 thus has a fir tree-like shape, the tip of which faces the free end of the nozzle 20.
- the tube 16 can be heated in its end region so that it can be expanded and pushed onto the connector 20 over the collar 34.
- the tube 16 shrinks again, the collar 34 clawing into it and thus holding the tube 16 on the nozzle 20 so that it can no longer be removed.
- the tube 16 can also be installed without heating, the end of which is pushed onto the connector 20 with the appropriate application of force. In the maximum pressure range, the plastic material of the tube 16 settles, so that it clings to the fir tree profile of the connector 20 and thus secures the tube 16 against being pulled off.
- the tube 16 has an outwardly projecting abutment bead 36 on its outer circumference near the connector 20 in a region projecting beyond the connector 20.
- the abutment bead 36 can advantageously be formed by a shaft section of the tube 16, of which a plurality of strings, as described above, form a section of the tube 16 in the form of a corrugated tube that can be flexibly bent. If removal of the pipe 16 or the fuel delivery unit 10 is required, it can the tube 16 are separated so that, as shown in FIG. 3, a remaining piece 16a with the abutment bead 36 remains on the connector 20.
- the remaining piece 16a of the tube 16 then forms a new connection piece, on which a new fuel line 23 in the form of a flexible hose can be fastened.
- the tube 16 is preferably cut off immediately after the contact bead 36, so that the free end of the remaining remnant piece 16a tapers approximately conically, which facilitates the subsequent pushing on of the hose 23. Since the contact bead 36 protrudes beyond the connector 20, it is ensured that the connector 20 is not partially removed when the tube 16 is cut off.
- the contact bead 36 prevents the hose 23 from slipping, which can optionally be additionally secured on the rest piece 16a arranged on the connector 20 by means of a hose clamp 38.
- the remaining piece 16a of the pipe 16 on the socket 20 is smoothly formed on the outer circumference outside the contact bead 36, that is to say that the collar 34 does not press through it, so that the connection of the hose 23 to the new socket is durable.
- FIG. 4 shows the tube 16 according to a second exemplary embodiment, in which the contact bead 36 is arranged on the area of the tube 16 arranged on the connector 20.
- the pipe 16 can have a marking 40 in its area protruding beyond the connection piece 20, for example in the form of a notch at which the pipe 16 should be cut off without part of the connection piece 20 also being cut off.
- the abutment bead 36 may end at approximately the same height as the socket 20 or may already end on the socket 20, so that even a smooth section of the remaining piece 16a of the tube 16 remains on the socket 20 after it has been separated.
