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.

A filter device (10) includes a filter element (12) in a filter housing (14) with fluid connection points (16, 18) for the non-filtrate and filtrate. Fluid can be passed through the filter element in both directions for filtrating the non-filtrate or for backwashing for cleaning particle contaminations (72). A pressure control (36) generates a post-suctioning effect to improve the cleaning of the particle contaminations (72). The filter device (10) is designed as a one filter-element solution. In a predetermined exchange, the single filter element (12) for filtering can be used for backwashing or can be backwashed using the pressure control device (36). A hydraulic system (64) and a method for backwashing a filter element (12) of a filter device (10) is provided.

A filter assembly has a threaded cover that mates with a complementary thread on the filter housing. Rotation of the housing cover in a first direction moves the cover axially away from the housing, and rotation of the housing cover in a second direction opposite the first direction moves the cover axially toward the housing. An intermittent coupling between a filter housing cover and a filter element applies intermittent axial forces to the filter element as the housing cover is rotated in the first direction to separate the filter element from the housing along with the cover. The intermittent coupling includes components on the inside of the filter cover that engage with complementary components on the filter element during each revolution of the cover.

A method to determine at least one filter operating parameter. At least one transponder arranged on or in a filter cartridge of the filter is contactlessly queried by a reading device. A transponder response is analyzed to evaluate the operating parameter. The transponder is subject to influences acting on the filter cartridge. As a result of the influences that the transponder is sensitive to, or sensitivity on transparency or damping properties of a transmission path of electronic signals between the transponder and the reading device, a transponder response behavior is changed to a degree detectable by the reading device or a downstream analysis unit which enables a statement to be made about the operating parameter. A device for determining at least one operating parameter of a filter or a filter cartridge arranged on or in the filter, and a filter cartridge are both provided.

A system includes an oil catch compartment, at least one magnetic stud or rod, a motor compartment, and a switch. The oil catch compartment includes a first end configured for coupling to an oil filter. The at least one magnetic stud or rod is positioned along a sidewall of the oil catch compartment. The motor compartment includes a gearbox shaft and a puncturing device. The gearbox shaft is telescopically coupled to a second end of the oil catch compartment. The puncturing device is coupled to the gearbox shaft and positioned at least partially within the housing of the motor compartment or the oil catch compartment. The switch is formed on an outside surface of a battery compartment and communicatively connected to a motor coupled to the gearbox shaft. The switch is actuatable to cause the motor to advance the puncturing device via the gearbox shaft.
