A liquid filter for a motor vehicle may include a hollow cylindrical housing bowl, a cover that closes the housing bowl, a suspended, hollow cylindrical particle filter arranged in the housing bowl, a catch basin that is opened towards the cover, and an edge overflow. The particle filter may extend parallel to a longitudinal center axis of the housing bowl and may divide the housing bowl into a clean liquid chamber and into a raw liquid chamber. The raw liquid chamber may be fluidically connected to at least one inlet arranged in the cover and the clean liquid chamber to at least one outlet arranged in the cover.

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.

The present invention relates to a filter device for separating debris from a fluid. The filter device includes a housing having at least one inlet, at least one first outlet, and a second outlet. The filter device further includes a filter cartridge that allows fluid to pass therethrough but prevents passage of debris therethrough. The filter cartridge is positioned within the housing so as to define an upper chamber and a lower chamber within the housing. The at least one inlet is positioned so as to allow contaminated fluid to enter the lower chamber of the housing. Fluid must pass through the filter cartridge in an upward direction to reach the upper chamber, and the first outlet is positioned so as to allow filtered fluid to exit the upper chamber. The second outlet is positioned to allow debris accumulated within the lower chamber to be discharged.

The following summary of the invention refers to the development of a multiple filtering device composed of three filtering elements (01 to 03) that are concentrically mounted on the lid (09) in the sequence EF1 (01), EF2 (02) and EF3 (03) with mesh measurements of different microns, forming four filtering chambers, with the purpose of retaining solids from agricultural spraying mixtures, monitoring the restrictive framework of the filtering elements through pressure switches (69.2) and pressure transducers (77) and alerting the obstruction through audio visual signaling (83, 83) so that the operator knows the exact moment to clean the multiple filtering device.

A filter cartridge for use in the interior of a water tank of a household appliance, the wall of which separates a housing internal side from a housing external side. A filter inlet opening which in the operation of the filter cartridge is open in relation to the external environment of a filter housing. A device for water conduction comprises at least one filter chamber having at least one filter medium and terminates in a filter outlet opening for suctioning water from the filter cartridge in the interior of the filter housing, downstream of the filter inlet opening relative to the flow direction of the water during operation. A filter port has an annular filter sealing face for the connection of the filter cartridge in a water tank. The filter sealing face has a separately disposed filter-proximal guide structure for receiving a centering element for centering the filter cartridge.
