  • Patent number: 10252207
    Abstract: A filter element for filtering media with a pleated filter medium is described. Each pleat (6) is formed by two pleated sheets which form a pleat tip (7) with one another on the crude side (3) exposed to oncoming flow. Two neighboring pleats (6) form a pleat base (8) with one another, wherein the crude side (3) and/or the clean side (4) of the filter medium has a plurality of elongated adhesive sections along at least two adhesive traces (14), each having at least one adhesive section and each having at least one adhesive interruption (15). The mutual spacing of the two pleated sheets in the region of the pleat tip (7) is between zero and two mm or the two pleated sheets are in contact with one another in the region of the pleat tip (7), wherein the pleat spacing (9) between the two pleated sheets of a pleat pocket (11) amounts to at least twice the pleat spacing in the region of the pleat tip 7 in the region of the pleat base (8).

  • Publication number: 20080035537
    Abstract: A fuel filter system characterized by a simple design provided with a coalescer element (20) disposed in the immediate fuel inlet region for improving the elimination of water droplets. The coalescer element includes an upper end plate (26) that extends to the inner wall of the housing (10), thereby sealing the coalescer element as well as the inlet region and the outer unfiltered fluid region. The coalescer element (20) and the particle filter (19) are arranged on a common separating element (25), which rests against the discharge tube (17) located in the center of the fuel filter via a profiled seal. The end plate of the coalescer element can be produced with the profiled elastomeric seal molded thereon by two-component injection molding or by overmolding.

  • Publication number: 20030226792
    Abstract: The invention relates to a multi-layer filter element. The invention provides a main filter layer which preferably consists of a melt-blown fleece and has an absolute filtration capability. A paper layer (2) on the clean side supports the filter element and does not contribute to the filtering of the fluid to be filtered. Said layer can therefore have a macropore structure, thereby allowing a low flow resistance. A layer (3)on the clean side which preferably also consists of paper serves to pre-filter the fluid and to protect and support the main filter layer. The inventive design of the multi-layer filter material provides a means for economically producing filter elements, especially filter cartridges which are folded in the shape of a star, since no trellis protective layers are necessary. The invention also facilitates an improved thermal disposability of the proposed filter cartridge.

  • Publication number: 20020056684
    Abstract: A multi-layer filter element for filtering fluids, in which a plurality of layers of filter media follow each other in succession in the direction of flow through the filter. All of the individual filter layers are preferably made of synthetic fibers, especially polyester fibers. The successive filter layers exhibit an increasing degree of filter fineness in the direction of flow through the filter, and the filter material contains at least one filter layer arranged on the inflow side of the filter which is composed of a meltblown fiber nonwoven web, especially a polyester fiber web.
