- the invention also relates to a
- From DE 10 2010 062 813 A1 is a generic fuel filter with a first ring filter element arranged therein, a second
- Ring filter element and a third ring filter element known, all ring filter elements are arranged coaxially with each other and at least two ring filter elements offset in the axial direction to each other. All ring filter elements are also connected in series and therefore flows through one after the other. In order to keep the maintenance of this fuel filter as simple as possible, the ring filter elements are also separate and therefore individually interchangeable. Within the ring filter elements while a function carrier is arranged, which is constructed in several parts and has channels for guiding different fluids.
- a disadvantage of the known from the prior art fuel filter is the structure of the function carrier, since this must not only be initially assembled from several items, but also a
- the present invention addresses the problem of providing a fuel filter of the generic type with an improved or at least one alternative Specify embodiment, which in particular is smaller and easier to manufacture.
- the present invention is based on the general idea to form a function carrier previously used in known fuel filters now for the first time as a one-piece, rod-shaped plastic injection molded part and at the same time on the design of the injection mold all for the function of
- one piece means, for example, that a body of the
- Fuel filter on a function carrier which has three separate channels for guiding three different media, wherein the first channel has a radial input, an axial output and a U-shaped deflection.
- This U-shaped deflection has hitherto been formed by the function carrier and a surrounding component, whereby not only a mounting of the
- the fuel filter according to the invention has in a known manner an at least two-part housing, in which a first annular filter element is arranged.
- a second and optionally a third annular filter element is additionally provided, wherein at least the first and second annular filter elements are arranged coaxially with one another and connected in series and thus can be flowed through in succession.
- the function carrier according to the invention is in a modified, that is in particular multi-part, form already in conventional Fuel filters used centrally and within the ring filter elements.
- the body of the function carrier can be embodied in a single
- the first channel is designed as a fuel channel, the second channel as a water channel and the third channel as a vent channel.
- the vent passage that is in the present case, the third channel, a venting of the fuel filter can be done, resulting in proper operation and to achieve the full
- Filtering capacity is required.
- the water deposited on a ring filter element such as a coalescer from the fuel can be removed, for example, in a location below the ring filter elements Wasserammeiraum.
- the fuel passage from the clean side of the third takes place via the first channel
- the third channel passes axially through the function carrier.
- the first channel has a radial input, a radial output and a U-shaped deflection, the first in the axial direction along the fuel
- Water channel extending substantially at right angles between a radial inlet and an axial, bottom-mounted outlet, which is connected to, for example, a water collection chamber.
- the first ring filter element is designed as a particle filter, whereas the second ring filter element as a coalescer and the third
- Ring filter element are designed as hydrophobic end or as a particle filter.
- first filter stage that is, at the first ring filter element
- dirt particles are filtered out and also achieved at least a low coalescence of entrained in the fuel water.
- second ring filter element that is, here at the second filter stage, which is formed for example as a pure Koaleszerography further coalesced, that can be increased.
- Ring filter element can be used for example cellulose, even native cellulose, which can be used in particular in the form of a fabric, a knitted fabric, a knitted fabric or a nonwoven.
- a fine-meshed network of hydrophobic material can be provided, so that the third ring filter element acts as Endabscheider that of the first and second filter stage prevents enlarged water droplets at the passage and separates.
- the already pre-cleaned by the first and second filter stage fuel is filtered again at the third filter stage by the third ring filter element and at the same time dewatered.
- the three-stage fuel filter according to the invention it is possible to achieve a particularly high and optimized filter effect, in particular with regard to dirt and solid particles, as well as significantly improved dewatering of the filtered fuel. As a result, in particular the risk of corrosion can be significantly reduced.
- the present invention is further based on the general idea to provide a function carrier for installation in a previously described fuel filter, which is one-piece, rod-shaped and formed as a plastic injection molded part and three separate channels for guiding three different fluids, namely air, fuel and water, wherein the first channel has a radial input, an axial output and a U-shaped deflection.
- a function carrier for installation in a previously described fuel filter, which is one-piece, rod-shaped and formed as a plastic injection molded part and three separate channels for guiding three different fluids, namely air, fuel and water, wherein the first channel has a radial input, an axial output and a U-shaped deflection.
- Functional carrier can be ensured by the one-piece embodiment, a high-quality manufacturing, since in particular a large part of previously required in more parts executing functional carriers

- a fuel filter 1 has a usually two-part housing 2, in which at least two, optionally even three
- Ring filter elements 3, 4 and 5 are arranged. In the example shown, a fuel filter with three ring filter elements 3, 4, 5 is shown. The first
- Ring filter element 3 is designed as a particle filter, whereas the second ring filter element 4 is formed as a coalescer.
- Ring filter element 5 in turn can be configured as a hydrophobic end separator and as a particle filter. All ring filter elements 3, 4 and 5 are flowed through radially, all from the outside to the inside. Theoretically, of course, it is also conceivable that the second ring filter element 4 is arranged axially offset from the first ring filter element 3 and in this Embodiment is flowed through from the inside to the outside. All ring filter elements 3, 4, 5 are also connected in series with each other and thereby flows through successively. In addition, it can be provided that the individual ring filter elements 3, 4 and 5 can be replaced separately and thus individually, whereby the maintenance of the fuel filter 1 according to the invention can be significantly simplified.
- Function carrier 6 is arranged, which is designed as a one-piece, rod-shaped substance injection molded part and three separate channels 7, 8, 9 for guiding three
- the function carrier 6 shown is composed of different parts, so not in one piece.
- the first channel 7 is designed as a fuel channel, whereas the second channel 8 are designed as a water channel and the third channel 9 as a vent channel.
- the first channel 7 has a radial input 10 (compare also FIGS. 2 to 7), an axial output 11 and a U-shaped deflection 12.
- the second channel 8 extends substantially at right angles between a radial input 10 'and an axial output 1 1 '.
- the third channel 9, however, runs the function carrier 6 axially and thereby has both an axial input and an axial output.
- the fuel filter 1 according to FIG. 1 could also be a
- function carrier 6 shown in FIGS. 2 to 7 are used, whereby then an inventive fuel filter 1 would be realized.
- Function carrier 6 and the third ring filter element 5 are provided.
- the functional support 6 according to the invention Due to the design of the functional support 6 according to the invention as shown in FIGS. 2 to 7 as a one-piece plastic injection molded part, its quality can also be increased considerably. In addition, the one-piece function carrier 6 can also be made cheaper, since only the assembly of two
- Function carrier components namely a particular in each case integrally molded body 21 and a lid 22 is required.
- One piece means in this case, for example, that the body 21 of the function carrier 6 is formed as a one-piece plastic injection molded part and then connected to the associated lid 22, in particular glued or welded, is. In the best case, there is thus the one-piece according to the invention
- Function carrier 6 from only two parts 21 and 22, which greatly simplifies the assembly.
- Ring filter element 3 and the function carrier 6 is reduced, which leads to a lighter rotational movement to position a pin 17, which in turn the risk of shearing the pin 17 can be reduced.
- To the others are the holding forces for releasing the ring filter element 3 from
- the ring filter element 3 is also more favorable, which is positive for the end customer in the case of service.
