  • 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: 8501002
    Abstract: The invention concerns a filter insert (1) that is provided as an exchangeable insert in a filter, in particular an oil filter, fuel filter or the like of an internal combustion engine. The filter comprises a filter housing (3) that can be separated along a separating plane (2) and the exchangeable filter insert (1) extending in an axial direction (18). Two housing parts (4, 5) of the filter housing (3) are sealed relative to one another along the separating plane (2) by means of a seal (6). The seal (6) is secured slidably and captively in the axial direction (18) on the filter insert (1).

  • Patent number: 7608184
    Abstract: A liquid filter, in particular for the lubricating oil of an internal combustion engine, having a housing with an inlet and an outlet formed from a housing pot having a substantially downwardly open filter element installation opening and a screw-on cover that closes the installation opening, and a filter element arranged in the housing, sealingly separating the inlet from the outlet. The screw-on cover has a drain for residual liquid present in the housing with a round drain opening arranged in the central axis of the housing. A device for opening and closing the drain opening is arranged in the area of the drain and connected to an end disk of the filter element so that it moves relative to the drain opening and opens the drain when the cover is unscrewed.
