  • Publication number: 20200108337
    Abstract: A filter arrangement for liquids has a filter housing and a functional carrier arranged inside the filter housing. A cylindrical filter element is inserted axially into the filter housing and defines an unfiltered side and a filtered side inside the filter housing. A non-return diaphragm is arranged on the filter element within the filter housing, wherein the non-return diaphragm is connected to the functional carrier and held at an axial spacing against a stop of filter housing so as to effect an axial and/or radial sealing action of the unfiltered side relative to the filtered side of the filter arrangement.

  • Patent number: 10556200
    Abstract: In a method for producing two or more filter bellows, a bellows with a filter medium with fold edges is provided, wherein the filter medium is running in a running direction. A cutting path is carried out in the bellows with the filter medium in a direction that, at least in some regions, is transverse relative to the fold edges such that the filter bellows are produced in parallel and the cutting path creates end edge faces and/or side faces of the filter bellows and the filter bellows are embodied lying adjacent to each other and symmetrical or point-symmetrical relative to each other in the running direction and/or transverse to the running direction. A filter element with such a filter bellows and a filter system with such a filter element and filter bellows arranged in a filter housing are provided.

  • Patent number: 10335718
    Abstract: A filter insert for a filter for filtering a fluid having] an inflow surface, and outflow surface, and a main throughflow direction. A filter body of the insert has a filter medium with pleats forming a pleated bellows, are arranged perpendicular to the main throughflow direction. A first number of the pleat edges form the outflow surface and a second number of the pleat edges on a pre-filtration side of the filtration body form the outflow surface. A first seal prevents the fluid from overflowing from the pre-filtration side to the post-filtration on a surface formed by a first number of of end face of the pleats. A second seal prevents the fluid from overflowing from the pre-filtration side to the post-filtration side on a surface formed by a second number of end faces of the pleats.

  • Publication number: 20180361300
    Abstract: A filter bellows with zigzag-folded filter medium has first and second fold edges extending between opposite end edge faces of the filter medium. The filter bellows has opposite end faces with an end fold. The filter bellows in use has a raw fluid-side surface and a clean fluid-side surface. First fold edges are positioned at the raw fluid-side surface and second fold edges are positioned at the clean fluid-side surface. The filter bellows has a passage extending between raw fluid-side surface and clean fluid-side surface. The passage has a first opening at the raw fluid-side surface provided with a first cross section and a second opening at the clean fluid-side surface provided with a second cross section. When projecting the first and second openings onto each other, one cross section, at least with sections thereof, is arranged outside of the other cross section.

  • Patent number: 9670805
    Abstract: A filtering system (9) includes a filter head (12) and a replaceable filter (10). The filter head (12) has a feed line (66) and discharge line (62). The replaceable filter (10) is removable and replaceably mounted onto the filter head (12) by a rotational and/or plug connection (15) and includes a housing (17) with at least one inlet (26) for oil to be filtered and at least one outlet (28). The inlet (26) communicates with the feed line (66). The outlet (28) communicates with the discharge line (62). The housing (17) has a filtering element (34) that sealingly separates the inlet (26) from the outlet (28). The filter head (12) includes an auxiliary oil line (60). The replaceable filter (10) has a flow control element (53) that automatically closes or releases the auxiliary oil line (60) dependent on an operation and/or assembly condition.
