Definitions

  • the invention relates to a filter cartridge in particular for an intake air filter of an internal combustion engine according to the preamble of the main claim.
  • a filter cartridge of this type is described in DE 88 05 049 Ul.
  • such filter cartridges have the disadvantage that the outer edge of the support and sealing ring can detach from the filter paper web in cases of extreme stress, since there is only a non-positive connection there. There is then a direct connection between the unfiltered air inlet and the clean air outlet, the passage cross section of which is small, but which can nevertheless result in malfunctions or increased wear on the downstream internal combustion engine.
  • DE-OS 27 38 086 shows a filter cartridge consisting of a filter material part and a flange part cast thereon from a pourable, hardened material e.g. There is plastic or rubber, which remains flexible after curing.
  • the filter material is embedded in the flange material in the end area.
  • a disadvantage of this known filter cartridge is that a casting mold is required for casting on the flange part, which results in a long cycle time and therefore low productivity in connection with the relatively slow curing.
  • the invention has for its object to avoid the disadvantages mentioned and to create a filter cartridge that consists of a few parts or components and at the same time ensures a reliable seal between the raw air side and clean air side.
  • the main advantage of the invention is the fact that the end plate, in which the sealing element is already integrated, is connected directly to the filter body, that is, the connection is made by melting the end plate and pressing it into the filter body. Due to the surface structure of the filter body or the zigzag-shaped pleated filter material, an intimate and reliable connection between the end plate and the filter body is achieved.
  • the end plate consists of a mixture of polypropylene and elastomer, which is also known under the term Santoprene, or of a mixture of polyamide and elastomer.
  • the advantage of this material is that it changes from rigid to pasty when heated and can thus be fused with the filter paper body.
  • the material shows a soft elastic property that is suitable for the fact that the washer can also be used as a sealing element.
  • the sealing element consists of a lip seal which, for example, has a plurality of sealing grooves.
  • a kind of labyrinth seal can thereby be achieved.
  • the arrangement of sealing grooves has the advantage that the elasticity behavior can be set exactly.
  • the end plate is an injection molded part and can be produced in a design using the so-called 2-component process. This means that plastics with different properties are melted together in a single operation.
  • the sealing element can consist of a plastic that has particularly good sealing properties.
  • the element to be fused with the filter body can consist of a plastic which has particularly good adhesive properties.
  • a further development of the invention provides for the sealing element to be arranged axially or radially. While the axial sealing of a filter cartridge represents the previously usual sealing, the radial sealing has the advantage that length tolerances of the filter cartridge can be compensated for more easily.
  • FIG. 1 a half section of an air filter with a filter cartridge
  • FIG. 1b shows a variant of an air filter with a filter cartridge
  • FIG. 2 shows a sealing profile with a cavity
  • Figure 3 shows a sealing profile with an open edge seal.
  • the embodiment of the air filter consists of an air filter housing 10 which is closed with a cover 11.
  • the filter housing has a raw air inlet 12 and a clean air outlet 13.
  • Inside the filter housing there is a filter cartridge 14 which is provided with an end plate 15 at its upper end and with an end plate 16 at the lower end.
  • the filter cartridge consists essentially of a zigzag folded filter paper 17. Both the end plate 15 and the End plate 16 consists in particular of Santoprene, a combination of polypropylene and an elastomeric material.
  • sealing lips are formed on the lower end disk 16. These sealing lips 18 have sealing grooves 19, 20 which contribute to an increase in the sealing effect.
  • the end disks are heated during assembly with the filter paper 17 and melted into the paper bellows and connected to it.
  • FIG. 1b also shows sealing lips 21. These provide a radial seal on the attachment 22 of the clean air outlet 13. If the end plate 16 is produced, for example, in a two-component injection molding process, it is expedient to design the first component as an easily meltable flat plate and to provide the second component for the sealing area.
  • FIG. 2 shows an air filter cartridge in which a sealing profile is arranged on the end plate 16, which brings about both a radial and an axial seal.
  • This sealing profile is produced in the so-called gas internal pressure process, that is to say the cavity 23 of the profile seal is created during the injection molding process by blowing in gas. This results in a seal that can be adjusted in terms of elasticity to the requirements regarding the stability of the filter insert.
  • Both TPE and polyamide are suitable as sealing or end plate material.
  • Figure 3 shows a variant.
  • the sealing profile is an open profile.
  • the seal effects both a radial and an axial seal or a seal in the axial direction and a position stabilization of the filter cartridge 14 in the radial direction.
  • both functions that is to say the sealing functions, the position stabilization are optimally fulfilled.
