Definitions
- the invention relates to a device for conveying Fuel from a storage tank to the internal combustion engine Motor vehicle according to the preamble of claim 1.
- Such a device is known from DE 38 27 572.
- This device has one arranged in the storage tank Container in which a storage space and a suction space are formed are.
- a conveyor unit is located in the container, draws the fuel from the suction chamber and to the internal combustion engine promotes.
- There is a valve in the bottom of the container arranged by the suction chamber in a first position separated from the storage space and connected to the storage tank is. The valve is in this first position, if sufficient in the storage tank in the area of the bottom of the container Fuel is present.
- the suction chamber is separated from the storage tank and connected to the storage space.
- the valve In this second position the valve is located in the storage tank in the area of the There is no fuel at the bottom of the tank could suck in the conveyor.
- the container with the bottom is formed in one piece. The container must go to the Installation conditions of the storage tank with regard to its dimensions, in particular its height, to be precisely adjusted, so that it is not possible to use for different storage tanks different installation conditions to the same container use. Rather, it is necessary in the known device a special container for each storage tank to provide, which leads to high manufacturing costs.
- the device for conveying fuel according to the invention from a storage tank to the internal combustion engine of a motor vehicle has the advantage that the container on easily adapted to different installation conditions can be.
- a strand profile is made by extrusion manufactured and from this the tubular part separated for the container in the required length.
- Figure 1 shows a simplified schematic diagram a device for conveying fuel a storage tank for the internal combustion engine of a motor vehicle
- Figure 2 shows a first embodiment of a in the storage tank arranged container with an arranged in this Conveying unit in spatial representation

- the attachment of the container 14 to the Supports 50 can, for example, by screwing Latched or otherwise flown.
- the length of the tubular part 32 of the container 14 is due to the installation conditions of the storage tank 10 adapted so that the bottom part 34 is arranged near the bottom 24 of the storage tank 10 and the upper end of the tubular part 32 to close to that Closing part 46 reaches.
- the tubular part 32 will of a long extruded profile in the for the installation conditions separated in the storage tank 10 required length.
- the bottom part 34 is used to form the container 14 connected to the tubular part 32, for example pressed in, whereby for sealing between the bottom part 34 and the tubular part 32, a sealing ring 33 are used can.
- the bottom part 34 has a cup-shaped Cylinder 51 on the one hand in the interior of the container 14 protrudes and on the other hand with its pot bottom 52 in Direction to the bottom 24 of the storage tank 10 via the bottom part 34 protrudes.
- Cylinder 51 closes a bowl-shaped receptacle 54 in which the lower end of the roller-shaped housing the conveyor unit 16 supports.
- a damping element 56 be arranged between the shot 54 and the housing of the conveyor unit 16 arranged.
- the conveyor unit 16 has one Intake manifold 58 in the cup-shaped cylinder 51st protrudes, but only so far that a suction space 60 in the Cylinder 51 remains.
- the suction space 60 is one or a plurality of openings 62 connected to the storage space 28. To do this, it must also be stated that between the tubular Part 32 of the container 14 and the conveyor 16 a gap remains free, through the exiting from the return line 26 Get fuel to the bottom part 34 in the container 14 can.
- the pot bottom 52 has one or more openings 64, which open into the fuel filter 22.
- a cup-shaped valve member 66 is arranged in the suction chamber is movable along the wall of the cylinder 51.
- the Valve member 66 is arranged in the suction chamber 60 so that the bowl bottom facing the pot bottom 52 of the cylinder 51 is.
- the bowl bottom of the valve member 66 has an opening 68 on, which is arranged so that it approximately with the opening of the suction nozzle 58 of the delivery unit 16 flees.
- the openings 64 in the pot bottom 52 of the cylinder 51 are arranged so that they are next to the breakthrough 68 remaining remainder of the cup bottom of the valve member 66 are covered when the valve member 66 with its cup bottom rests on the pot base 52.
- the valve member 66 shown in a first position in which it with his Cup bottom on the end face 69 of the suction nozzle 58 of the conveyor unit 16 is present.
- valve member 66 With its cup bottom Pot bottom 52 of the cylinder 51, so that there the openings 64 are closed while the openings 62 are released are.
- the valve member 66 is slightly heavier than the amount of fuel corresponding to its volume.
- the cylinder 51 and the receptacle 54 for the delivery unit 16 can also be separated from the bottom part 34 as an in the container 14 inserted part may be formed.
- the device operates as described below.
- the storage tank 10 is filled with working Pump sucks this from the suction chamber 60 and fuel simultaneously pulls the valve member 66 into its in FIG. 4 First position shown, in which the openings 62nd are closed and the openings 64 are released.
- the pump to be pumped flows Fuel through the fuel filter 22 through the Openings 66 in the pot bottom 52 and the opening 68 in the Napfêt in the suction chamber 60 and is there from the conveyor unit 16 sucked in and conveyed to the internal combustion engine 12.
- the valve member 66 occupies this first position for as long as the delivery unit 16 from the suction chamber 60 fuel can suck the fuel filter 22. During this Time becomes the storage space 28 through the return line 26 fuel flowing back.
