Abstract: A fluid filter for a motor vehicle includes a filter housing and a filter cartridge which is fixable on the filter housing by rotating around a longitudinal axis of the filter cartridge. A holding element having a web is disposed on an end plate of the filter cartridge where the web protrudes from a wall of the holding element and where the wall is formed as a spiral shape. The web of the holding element is engageable behind a holding web of a counter bearing disposed on the filter housing that is spiral shaped. The holding web has an incline in a rotational direction in comparison to an abutment region of the filter housing on which a sealing element of the filter cartridge abuts.

Abstract: A filter arrangement for threadably securing to a filter head includes a housing having a surrounding wall defining an interior volume, an open mouth providing access to the interior volume and an end opposite of the open mouth. The surrounding wall has an exterior and an interior. A filter media construction is operably held within the interior volume. A sleeve, distinct from the housing, is secured to the exterior of the surrounding wall adjacent to the housing mouth and extending partially along the surrounding wall. The sleeve has an exterior and an interior. The exterior of the sleeve defines mounting threads constructed and arranged to removably mount with the filter head, when the filter arrangement is secured to the filter head. The interior of the sleeve is against the exterior of the surrounding wall. A first seal member is oriented against the sleeve to create a seal with a filter head, when the filter arrangement is secured to the filter head. A filter assembly includes a filter arrangement and a filter head. The filter arrangement is removably secured to the filter head by a threaded connection between the sleeve and the filter head. A system includes an engine utilizing a liquid and a filter assembly in fluid communication with the engine to filter the liquid. Methods of making filter arrangements include utilizing structures characterized above.
