Definitions
- the invention relates to a filter element and a filter system, in particular
- an air inlet opening is arranged at the periphery of the housing.
- the housing has a substantially cylindrical filter element
- End disk which is a substantially cylindrical, radially inwardly gerich ⁇
- the known from the above-mentioned US-type filter cartridge and other commonly used filter cartridges consist of a combination of materials, in particular steel sheet is used for the support tubes.
- the filter medium is paper or a plastic fleece.
- the end plates are made of plastic, for example a soft elastomer.
- the reliable and process-reliable sealing of the filter element in a housing is important.
- the seal should be made temperature resistant and vibration resistant. Even in systems or facilities that are exposed to strong vibrations or vibrations, the sealing of the filter element must be ensured. At the same time, however, the filter element itself should as far as possible have no metallic elements so that it can be easily disposed of thermally.
- the invention is therefore an object of the invention to provide a filter element and a filter system with a high filtration property and a reliable seal between the region of the unfiltered and the region of the filtered medium. This object is solved by the features of the main claim.
- the main advantage of the invention is that it is ensured by the design of the seal of the filter element with a V-shaped arrangement and a sealing groove located between the legs is that on the one hand a high sealing effect and on the other hand a good support of the filter element is achieved in a housing. Especially with the use of plastic and the sealing of vibration-loaded elements a design is required, which works reliably even with extreme temperature fluctuations.
- the end plate which carries the seal, made of a two-component plastic.
- a hard component is provided as a carrier.
- an elastomer or a foamed plastic material in the form of a V-shaped seal.
- connection between the hard components and the filter medium with an elastomer or a foamed plastic material, wherein this compound component can also be produced by the two-component injection molding process.
- the end plate can also be attached to the filter element via a mirror welding process. It is also possible to heat the end plate with infrared rays and to embed the filter element in the heated thermoplastic.
- V-shaped seal extends over the end faces of the double web and thus create the defined contact of the filter element to a housing.
- the invention also relates to a filter system with a filter element.
- This filter system is used in particular for filtering the intake air of an internal combustion engine and consists of a housing and a lid for receiving the filter element.
- the end plates can also be produced in the thixotropic application process. This means a metering of the thixotropic material in which at the same time the sealing structure is formed without additional shell molds.
- the filter system is equipped with two annular grooves which communicate in the region of the seal with the sealing contours of the filter element.
- a cyclone or rotary flow is arranged on the housing in the region of the inlet.
- This consists of guide ribs, which set the medium to be filtered in a rotation or rotation. This movement causes the dirt to escape directed and especially ⁇ at a suitable location via a dirt outlet
- FIG. 1 shows the detailed representation in the sealing region of the filter housing.
- the filter system according to Figure 1 consists of a housing 26, which
- the filter system is used for filtering the intake air of Brennkraft ⁇
- Arranged 38 flows through a Zyklonvorabscheider 34 and is
- a suitable valve can be closed, carried to the outside.
- a middle piece 37 is arranged on the housing 26, a middle piece 37 is arranged. This is also
- Lid, centerpiece and housing thus constitute a closed system, which has an outlet 29 for discharging the purified air.
- a filter element 39 This consists of a zigzag folded filter medium 10 and is constructed in a concentric shape. At the end faces, the filter element 39 has end disks 11, 12. While the end disk 12 has a concentric opening 13, the further end disk 11 is closed by a closure piece 24. The air to be cleaned flows according to the arrow 41 through the filter element and according to arrow 42 cleaned via the outlet 29 to an internal combustion engine, not shown here.
- the filter element has on the left side arranged end plate 12 a double web 14. Between the two webs of the double web, a V-shaped seal 16 is arranged. This V-shaped seal extends with its two legs over the end faces of the double bridge. It also has in the inner region of the two legs circumferential sealing webs 21 a to 21 d. As a result, the V-shaped seal surrounds a sealing web 20 of the housing 26 and thus produces a seal. seal between the raw air area (area 20) and the clean air area 43.
- the end plate 12 is provided on the opposite side of the V-shaped seal with polyurethane foam 45.
- the filter medium 10 is embedded.
- the polyurethane foam itself extends up to the wall 46 of the housing 26 and forms together with this wall a seal for coarse dirt, so that no coarse dirt can penetrate the seal-relevant area 20, which may affect the sealing function.
- the filter element itself is supported in the region of the end plate 11 via support tabs 43a, 43b on the cover 27 and thus ensures sufficient axial force in the direction end plate 12 and thus for a reliable seal.
