Definitions
- the invention relates to a conveyor for conveying of fuel from a fuel tank to one Internal combustion engine of a motor vehicle with a feed pump and with one connected to the feed pump Flow line and with one arranged in the flow line Fuel filter.
- Such conveyors are used in today's motor vehicles frequently used and are known from practice (e.g. DE 19716979).
- the fuel filter to reduce one Escape of fuel into the environment within the Fuel tank arranged.
- the fuel filter must therefore have a service opening in the fuel tank be opened. Through the service opening and the seal escapes from the fuel tank however, a large amount of fuel in the area.
- the invention is based on the problem of a conveyor of the type mentioned in such a way that a promotion of fuel after adding the Fuel filter reliably secured with dirt and that there is an escape of fuel into the environment largely prevented.
- the supply line is one that leads past the fuel filter Has bypass line and that means for sealing the bypass line in the basic state and release the bypass line after a specified period of use or Consumption stage of the fuel filter are provided.
- the fuel bypassed the fuel filter can be according to another advantageous development simply filter the invention when in the bypass line a second fuel filter is arranged.
- the number of sealing points on the outside of the fuel tank can be advantageous according to another Keep further development of the invention particularly low, if the bypass line and that through the fuel filter leading area of the flow line inside the fuel tank are merged.
- the outside of the fuel tank another Position the fuel filter if the bypass line and the area of the supply line leading through the fuel filter one connection on the outside of each Have fuel tank and if the bypass line has a blind closure.
- the means for closing and releasing the bypass line are designed according to another advantageous Further development of the invention is structurally particularly simple, if they have a changeover valve arranged in the supply line exhibit.
- the changeover valve can be operated manually, for example if there is no fuel supply.
- the control of the means for locking and releasing the bypass line requires a particularly low one construction effort if the means to close and Release the bypass line from the pressure upstream of the fuel filter are controllable.
- the changeover valve is designed according to another advantageous further development of the invention is particularly constructive easy if it's a longitudinally slidable Has closing body.
- the switching valve can be controlled manually, for example or electrically controlled.
- the control of the changeover valve however requires according to another advantageous development of the invention a particularly little effort if the movement of the closing body in Dependence of the pressure of the feed pump is controllable.
- the switching valve can be advantageous according to another Development of the invention with particularly little Control construction effort electrically or manually, if the changeover valve has a rotatable closing body.
- Figure 1 shows an upper portion of a fuel tank 1 with a conveyor 2.
- the conveyor 2 has a feed pump 3 for conveying Fuel into an internal combustion engine, not shown leading flow line 4.
- the lead pipe 4 penetrates one inserted into an assembly opening 5 Flange 6.
- Inside the flow line 4 is a fuel filter 7 is arranged.
- the fuel filter 7 is parallel to one to one on the outside of the Flange 6 located blind closure 8 guided bypass line 9 arranged.
- FIG. 2 shows a conveyor 11, in which in the around the first fuel filter 7 bypass line 9 a second fuel filter 12 is arranged. Seen in the flow direction after the fuel filters 7, 12 is a switching valve 13 which is optional one or the other fuel filter 7, 12 with the area outside the fuel tank the flow line 4 connects. This can help clogging the first fuel filter 7, the switching valve 13 can be controlled so that the second Fuel filter 12 is flowed through with fuel.
- a switching valve 13 Seen in the flow direction after the fuel filters 7, 12 is a switching valve 13 which is optional one or the other fuel filter 7, 12 with the area outside the fuel tank the flow line 4 connects. This can help clogging the first fuel filter 7, the switching valve 13 can be controlled so that the second Fuel filter 12 is flowed through with fuel.
- Figure 3 shows a conveyor 14 in which a changeover valve 15 seen in the flow direction before Fuel filter 7 is arranged.
- the Switching valve can optionally fuel over the Fuel filter 7 or through the bypass line 16 through direct a second fuel filter 17.
- the second fuel filter 17 can initially be omitted and this only after switching the switching valve 15 in the outside of the fuel tank 1 Mount the area of the flow line 4.
- the conveyor 14 can also Provide multiple changeover valves, not shown, and two or more bypass lines with or without arranged therein Have fuel filters.
- FIG. 4 shows a changeover valve 18 as it is in the conveying devices 11, 14 used according to Figures 2 and 3 can be.
- the switching valve 18 has one with the feed pump 3 shown in FIGS. 2 and 3 connected port 19, one to the first fuel filter 7 leading connector 20 and a connector 21 for the bypass line 9, 16.
- a closing body 22 is longitudinally movable arranged, which is the terminal 21 of the bypass line 9, 16 can either lock or release.
- the closing body 22 has an external thread 23 and is in an internal thread 24 of the connection 19 of the feed pump 3 screwed in. Through an opening 25 is a slot 26 of the closing body 22 for attaching a not shown Turning tool accessible.
- Figure 5 shows a changeover valve 27 as it is in the conveyor 14 from Figure 3 can be used.
- the connection can be made 21 of the bypass line 16 from a longitudinally movable Release or close the closing body 28.
- the pressure in the connection increases 19 of the feed pump 3.
- the closing body 28 will then by the pressure of the feed pump 3 against the Force of the spring 29 moves until the terminal 21 of the bypass line 16 is released.
- FIG. 6 shows a changeover valve 31 as it is in the conveying devices 11, 14 from Figures 2 and 3 used can be.
- this changeover valve 31 is the Connection 19 for the feed pump 3 arranged centrally. From this connection 19 lead with the first fuel filter 7 connected connector 20 and connector 21 the bypass line 9, 16 away.
- a rotatable Closing body 32 allows connection 19 of the feed pump 3 optionally with the other two connections 20, 21 connect.
- the control of the closing body 32 can either electrical or manual.
