Definitions
- the invention relates to a pre-filter for a fuel Forderech a motor vehicle with a filter fabric, with a connection piece for connection to the fuel ⁇ pump and with a support element for Ab manufacturn the Filterge ⁇ web.
- Such pre-filters are often used in modern motor vehicles for filtering various fuels such as diesel or gasoline and are known in practice.
- a settlement of ferti ⁇ gen prefilter corresponding fabric section is punched out of a plastic fabric.
- This fabric blank is placed in a plastic injection mold ⁇ form.
- the injection mold usually several support elements and the connection piece are molded onto the fabric blank.
- the fabric cutting plates and supernatants are also provided at the fabric cutting plates and supernatants.
- the fabric blank is folded into the pre-filter and the edges are welded together and trimmed.
- a fabric blank In filters provided for diesel fuel, a fabric blank is usually deep-drawn from a metal fabric for an upper part and a lower part. These fabric sections ⁇ the then inserted individually into an injection mold and molded connection piece and supporting elements. Finally, the two fabric blanks are placed with their edges on each other and sealed by a frame.
- a disadvantage of the known pre-filter that it is very up-walled to manufacture and a large number of processing steps needed ⁇ .
- the invention is based on the problem of designing a prefilter of the type mentioned above so that it is particularly easy to manufacture and has a high stability.
- the filter fabric after the production of Stutz ⁇ element and connecting pieces can be attached with appropriate shaping of the support element. As a result, it is no longer necessary to inject the filter cloth in an injection mold with the support element and the connecting piece.
- the one-piece component consisting of connection piece and support element can be optionally connected with a plastic fabric for gasoline or a metal fabric for diesel fuels.
- the inventive pre-filter in the simplest case two components and is therefore especially a ⁇ times to assemble. The number of processing steps is also kept very low.
- a chamber for collecting the fuel let in accordance ei ⁇ ner advantageous development of the invention easily generate, when the supporting element has a nozzle rim and if literallyin- least one of the end faces of the neck edge on the filter cloth attached. Furthermore, the nozzle edge on a simple form for attachment of the filter fabric.
- the inventive pre-filter has a particularly large O- berflache of the filter cloth when a respective portion of the filter cloth is fixed up ⁇ tend to both end faces of the nozzle edge.
- a juxtaposition of opposing filter fabric can be according to another advantageous embodiment of the invention easily avoided when the filter fabric of the Stutzrand is curious. Furthermore, as a result of this, the prefilter according to the invention has a particularly high intrinsic stability.
- the Stutzrand could for example be designed U-shaped. To further increase the stability of the prefilter according to the invention, however, it contributes, if the support edge is formed as a ge ⁇ closed frame.
- the one-piece production of the connecting piece with the nozzle edge designed in accordance with another advantageous embodiment of the invention structurally particularly simple when the connecting piece is connected via webs with the nozzle edge.
- Pre-filter contributes according to another advantageous embodiment of the invention, when the nozzle edge has on its side facing away from the connecting piece transverse webs for Abstutzung the filter fabric.
- the nozzle edge can be finished with the connecting piece and the transverse webs in an axially demoldable tool mold, when the transverse webs are arranged offset relative to the connecting piece.
- the axial demoldability of the mold allows the use of a single mold for the entire pre-filter. This design contributes to particularly low production costs of the inventive prefilter.
- the connecting piece has ribs for Abstutzfilter the filter fabric and when the ribs are guided to the level of the opposite end face of the nozzle edge.
- the connecting piece has a flange for sealing connection with the filter fabric.
- the support element is made of plastic by injection molding.
- a white ⁇ more excellent advantage of this design is that after the production of the duct element, the gefertig- plastic te filter fabric thus particularly simple in the welding process on the supporting element secure initiated.
- the filter fabric can also seal on the support element.
- a filter fabric made of metal can easily be fastened in a material-tight and sealing manner after the connection points of the support element have melted on.
- FIG. 2 enlarges the prefilter from FIG. 1 in longitudinal section
- FIG. 3 is a sectional view through the prefilter of Figure 2 along the line III - III,
- Fig. 4 is a sectional view through the pre-filter of Figure 2 along the line IV - IV.
- FIG. 1 shows a fuel delivery unit 2 with a pre-filter 3 arranged on a base 1 of a storage container 4 of a motor vehicle.
- the prefilter 3 is arranged close to the bottom 1 of the storage container 4 and is connected via a connection 5 with the fuel demand unit 2 connected.
- the storage container 4 may be a fuel tank of a motor vehicle.
- the fuel demand unit 2 has an electric motor-driven fuel pump 6, is sucked through the fuel from the bottom 1 of the Vorratsbehalters 4 through the pre-filter 3 and required in leading to an internal combustion engine, not shown feed line 7.
- the prefilter 3 is shown enlarged in FIG. Here ⁇ wherein it can be seen that the pre-filter 3 has two arranged on a support element 8 flat portions 9, 10 of filter ⁇ fabric. 11
- the support element 8 has a support edge 12, on the end faces of which the sections 9, 10 of the filter fabric 11 are fastened.
- the Stutzrand 12 also biases the sections 9, 10 of the filter fabric 11.
- the Stutzrand 12 is einstuckig made with transverse webs 13.
- the transverse webs 13 are arranged offset from the connecting piece 5.
- the connecting piece 5 is also manufactured in one piece with Stutzrippen 14.
- the stub ribs 14 extend to the section 10 of the filter fabric 11 arranged away from the connecting piece 5.
- the connecting piece 5 has a flange 15, with which it is sealingly connected to one of the sections 9 of the filter fabric 11.
- Figure 3 shows in a sectional view taken along the line III - III through the pre-filter 3 of Figure 2, that the connecting piece 5 is connected via webs 16 with the nozzle edge 12.
- the nozzle edge 12 is designed as a closed frame.
- Figure 4 shows for clarity the pre-filter 3 in a sectional view taken along the line IV - IV of Figure 2.
