Definitions
- the invention relates to a delivery unit for a motor vehicle provided for fastening in a fuel tank with a delivery pump arranged in a housing and intended for drawing in fuel from a bottom area of a baffle and with a filter arranged upstream of the delivery pump as seen in the direction of flow
- Such conveying units are usually designed with an electric motor as a structural unit and inserted through an opening in the fuel tank.
- the filter has a bag-shaped filter fabric and is mounted on a pipe piece and is arranged close to the bottom of the baffle.
- the pipe piece is one-piece with a side part of the conveying unit
- the filter element has clips for locking with the pipe piece and lies to the side of the conveying unit
- a disadvantage of the known delivery unit is that it is complicated to assemble and has a high space requirement.
- the high space requirement due to the filter element protruding to the side means that the bottom area of the swirl pot must be designed to be very large, so that the delivery unit with an almost empty fuel tank and an inclined one Can not reliably suck Kiaftfahizeug
- the invention is based on the problem of designing a conveying unit of the type mentioned at the outset in such a way that it can be produced and assembled as inexpensively as possible and requires a particularly small amount of space in the bottom area of the plastic container
- This problem is solved according to the invention in that the filter is arranged within the housing of the feed pump
- the intake unit according to the invention requires a particularly small amount of space in its suction area, so that the swirl pot in the fuel tank can have particularly small dimensions.
- a filter element protruding from the delivery unit is therefore not necessary required to assemble the filter
- the requirement according to the invention can therefore be manufactured and assembled particularly inexpensively
- the filter further contributes to a further reduction in the space requirement if the filter is designed to be cylindrical in shape and with its two end faces rests on a side part each with a passage provided with fuel flow.
- Another advantage of this design is that that the door unit has a sandwich-like structure and is particularly easy to assemble
- the filter is held reliably in its position if it has a support ring for support on the side parts. Furthermore, the support ring serves as a spacer for the side parts, so that they can be easily clamped together during assembly contributes to further simplifying the assembly of the conveyor unit according to the invention
- a large surface of the effective area of the filter element can be easily generated if the filter element has a folded filter fabric
- the filter element is dei flow of the fuel completely flows when the ends of the channels of the side parts facing the filter element are arranged offset from one another.
- the filter element can filter the fuel in several stages if the filter element has a plurality of filter fabrics layered one on top of the other. This reliably prevents the filter fabric from clogging quickly.
- the filter fabric is reliably held in its intended position with respect to the flow of the fuel if the filter element has support elements for holding the filter fabric.
- degassing lines of the feed pump or branches for supplying a suction jet pump with fuel are frequently discharged downwards from the feed unit.
- such lines can simply be guided through the filter if the filter has ring elements fastened in the filter element for the passage of lines. If the support ring is made of plastic in a molded casting tube, it contributes to the further reduction of the manufacturing costs of the inventive conveyor unit.
- the support ring is designed for the lateral sealing of the filter element.
- the feed pump and the filter with the two side parts can simply be clamped together in a side part made of sheet metal, for example.
- the delivery unit according to the invention requires a particularly small number of components to be assembled if the support ring is made in one piece with one of the side parts.
- the invention allows numerous embodiments. Two further thereof are shown in the drawing for further clarification of their basic principle and are described below. This shows a floor area in FIG. 1 a fuel tank with a forcing unit according to the invention,
- FIG. 2 shows an enlarged sectional view through the lower region of the claim unit according to the invention from FIG. 1,
- FIG. 3 shows a sectional view through the conveyor unit from FIG. 2 along the line III-III
- FIG. 4 shows a lower region of a further embodiment of the conveyor unit according to the invention in partial section
- Figure 1 shows a floor area of a fuel tank 1 of a motor vehicle with a baffle 2 in the
- Swirl pot 2 is attached to a delivery unit 3 with a fordei pump 5, which is anoid in a housing 4
- a supply line leading to an internal combustion engine (not shown) can be connected to the connecting piece 9.
- the surge pot 2 has a bottom valve 10 designed as a check valve. Fuel can flow into the surge pot 2 through the bottom valve
- the filter 6, as shown in FIG. 2, is clamped between two side parts 11, 12 of the delivery unit 3.
- the filter 6 In its radially outer area, the filter 6 has a support ring 13 made of plastic by injection molding.
- the support ring 13 is sealingly glued to a filter element 14 having a folded filter fabric 15.
- the housing 4 of the delivery unit 3 is tubular and has at its end a flanged edge 16 which engages behind the outer side part 12 of the delivery unit 3. As a result, the side parts 11, 12 are clamped together with the filter 6 and the delivery pump 5.
- the filter 6 has an Rmg element 17 glued into the filter fabric 15 for the passage of a line 18.
- the line 18 can, for example, be a degassing line of the feed pump 5 or a? .Bzwe ⁇ g leading into the fuel tank 1 shown in Figure 1 ,
- the conveyor unit 3 from FIG. 2 is shown in a sectional view along the line III-III in FIG. 3. It can be seen here that the support ring 13 is made in one piece with a second ring element 19 for the passage of a line (not shown) through the filter 6.
- FIG. 4 shows a further embodiment of the filter unit 3 according to the invention in a section through a filter 20.
- the filter 20 here has a filter element 21 with a plurality of layered, flat-shaped filter webs 22.
- a side part 23 abutting the tilter 20 is in one piece with a support ring 24 of the filter element 21 manufactured.
- the filter fabric 22 has a plurality of support elements 26 resting on the side parts 23, 25.
