Definitions

  • Filter element especially for liquid filtering
  • the invention relates to a filter element, in particular for filtering liquids, and a method for its production according to the preamble of claim 1.
  • a filter element is known, for example, from DE 94 03 868.6 U1 with a zigzag-folded filter web, in which the filter web is folded in a star shape. The resulting hollow cylinder is flowed radially from the outside by the liquid to be filtered and the filtered liquid is led out of the filter element centrally.
  • the material of the filter web is paper, felt or a plastic fleece, these filter elements being inserted as a replaceable insert in a corresponding filter housing. After a certain operating time, these filter elements with the known filter material no longer have sufficient filter properties and must be replaced.
  • the invention has for its object to develop a filter element of the type mentioned in such a way that a long life of the filter element can be achieved with a simple structure retained.
  • the filter element according to the invention is advantageous, in particular for use as a liquid filter in a motor vehicle, with the features of the characterizing part of claim 1 in that with a filter fleece which contains metal or glass fiber, an extraordinarily long service life, possibly even corresponding to the service life of the connected unit, is made possible. This also simplifies the construction of the filter housing, since it is no longer necessary to replace the filter element.
  • the filter web is made from pre-embossed filter fleece plates or from a rolled-up filter fleece web and the individual surfaces of the zigzag shape are imprinted on the basis of the embossing Manufacturing process formed.
  • a mechanically stable filter element can be permanently formed, which retains the advantages of the relatively large filter surface even with a star fold, based on the respective installation space, and therefore does not fall back on the multi-layer arrangement, known per se, with various nonwoven materials.
  • filter fleece which consists entirely of metal fibers
  • filter webs of approximately 1 mm thickness can be produced in various pore sizes and fiber thicknesses, in particular made of stainless steel fibers.
  • the use of sintered metal fiber fleece is also advantageous.
  • the metal fiber fleece is particularly suitable for use in the thermally stressed oil filter area, whereby the fibers have sufficient capacity to store the dirt particles over a long service life without becoming brittle.
  • the filter fleece with different metal fiber diameters can be used in a single-layer design for certain filter fleece arrangements in terms of weight and cost.
  • the filter element as a glass fiber fleece, it can advantageously be laminated or coated on one or both sides with polyester fibers.
  • grooving or other embossing can be carried out in a simple manner and the glass fiber fleece can be processed to form a star-fold filter element without additional protective fleece on the upstream or downstream side and, if appropriate, also without supporting fabric.
  • the filter element according to the invention of the embodiments described above can preferably be used in the hydraulic area, in the manual transmission area, in the lubricating oil or fuel filter area of a motor vehicle or also in water filtration or in the filtration of aggressive media. With a suitable fiber thickness, no additional fine filters are generally necessary.
  • Figure 1 is a plan view of a star-shaped filter element
  • Figure 2 Examples of the knockouts on the filter path of the filter element.
  • FIG. 1 shows a filter element 2 which is provided with a star-shaped zigzag-folded filter web 1 and which is used, for example, for filtering lubricating oil in a motor vehicle.
  • the lubricating oil to be filtered is directed from the outside onto the filter web 1 and filtered out through an outlet in the center of the filter element 2.
  • FIG. 1 Individual areas of a filter web 1 made of metal or glass fibers designed according to the invention are shown in FIG.
  • different pre-embossments of the filter web 1 are possible, which are shown by way of example in FIG.
  • knockouts 3, 4 and 5 are provided transversely to the folded edge 6 on each individual surface of the filter web 1.
  • knock-outs are carried out on the folded edge 6 and in the extreme right-hand example, the previously described knock-out types are combined with one another.

Abstract

L'invention concerne un élément filtrant pour la filtration des liquides, comportant une bande filtrante (1) pliable en zigzag et constituée d'un non-tissé filtrant. Ce dernier contient des fibres métalliques, des fibres de verre et/ou des fibres polyester, la bande filtrante (1) pliée en zigzag étant réalisée à partir de plaques de non-tissé filtrant prégaufrées ou bien à partir d'une bande de non-tissé filtrant enroulée, et les faces individuelles de la forme en zigzag se forment à l'aide du prégaufrage (3, 4, 5, 6), de préférence en vue d'un pliage en étoile.
