  • Publication number: 20140061119
    Abstract: A plastic end disk for a filter element has a disk-shaped-section sealing an end face of a star-pleated bellows and has a hollow-cylindrical section extending away from the disk-shaped-section. An inner side of the hollow-cylindrical section radially seals the plastic end disk on a receiving pin by an O-ring. The hollow-cylindrical section has noses arranged on the inner side that extend into the interior the hollow-cylindrical section. The noses house an O-ring. The noses include first noses extending in a first plane parallel to the disk-shaped-section and second noses extending in a second plane that is spaced apart from the first plane in axial direction. The first noses are displaced relative to the second noses such that the first noses, when projected axially onto the second plane, and the second noses do not overlap and an undercut-free configuration of the plastic end disk is provided.

  • Patent number: 8114278
    Abstract: The invention concerns a fuel filter 10, in particular for diesel fuels, that comprises a housing 11 and a filter medium 12. The filter medium 12 is arranged by means of a filter medium holder 24 in the housing, wherein the filter medium holder comprises a venting bore 25. Through the venting bore 25 gases that collect in the upper area of the fuel filter can pass from the crude chamber 21 into the clean chamber 22. For avoiding that contaminants can escape through a clean outlet 18 from the fuel filter 10 and damage components downstream, a clean medium 26 is provided that retains such contaminants.

  • Publication number: 20060254975
    Abstract: A filter element for filtering a fluid, particularly oil, in which the filter element has at least two individual elements (10), that are interconnected by a connector (11). The individual elements (10) each include two end disks (13) and a filter medium (12) arranged therebetween. The connector (11) has a radially circumferential sealing bead (23), which communicates with the end disk (13) of an individual element (10) so as to form a seal and ensures a tight seal between the individual element (10) and the connector (11).
