A filtration assembly of a fluid of a vehicle extending along an axis includes a filtering cartridge and a filter body housing the filtering cartridge. The filtration assembly includes cartridge members and body members having engagement and disengagement configurations, respectively. The filtering cartridge includes an axial end plate on which the cartridge members are positioned. The cartridge members include blocking groups, each including a stem and a tooth projecting laterally and defining an engagement undercut. The body members include a housing region and a lug. In the engagement configuration, the tooth housed snap-fits in a respective housing region and the lug is housed in the undercut. The cartridge members and the body members include a cartridge border and a body border, to reciprocally engage in the reciprocal rotary actions so that the respective blocking group yields elastically radially in the reciprocal engagement between cartridge border and body border.

Support membranes for filters are described that include a support sheet formed of a polymeric material and a continuous base section having opposed outer surfaces and spaced-apart ribs extending outwardly from at least one of the opposed outer surfaces. The spaced-apart ribs define continuous flow channels bound by the adjacent spaced-apart ribs. The ratio of the height of the ribs to the height of the continuous base ranges from about 2:1 to about 5:1. This relatively high aspect ratio of the ribs and the base layer increases the performance of the filter and reduces the cross-flow pressure drop of fluids filtered through the membrane.

A filter element group for a filter device for filtering a fluid may include a ring-shaped working filter element, a ring-shaped protective filter element, an assembly device, and a securing device. The working filter element may include a ring-shaped working filter body, a first outer end plate, and a second outer end plate. The protective filter element may include a ring-shaped protective filter body, a first inner end plate, and a second inner end plate. The securing device may be adjustable between a securing state where the cover plate is axially secured to the second outer end plate and a release state where the cover plate is axially removable from the second outer end plate. When in the securing state, the securing device may secure the cover plate to the second outer end plate preventing rotation of the cover plate in the circumferential direction.

A filter element for a filter device may include a support structure extending along an axial direction, on which on a circumference side an annular filter medium consisting of filter material may be arranged, and an annular first end disc having a passage opening through which a first pin element may be passed, so that the first pin element may project out of the passage opening along the axial direction, wherein a second pin element may axially project from the first end disc laterally spaced apart from the first pin element.

A washing machine including a drainage pump to discharge water from a tub of the washing machine through a drainage passage, a first filter to which the water flows due to the drainage pump and provided along the drainage passage to filter out foreign matter equal to or greater than predetermined size, and a second filter to which the water flows from the first filter and provided along the drainage passage and to filter out foreign matter smaller than the predetermined size, wherein the drainage passage includes a first connecting hose to guide the water to flow from the tub to the first filter, a second connecting hose to guide the water to flow from the first filter to the second filter, and a drainage hose to guide the water to be discharged from the second filter to the outside of the washing machine.

A floatable filter has an outer member that has a top section and bottom section that are hollow. The top section has an inner edge and an outer edge with the outer edge having a diameter that is adapted to slide up and down an inner diameter of a storage container. Connected to the inner edge of the outer member is an internal grid. The internal grid includes members that crisscross to provide spaced openings. Further, the internal grid dwells in a plane below a horizontal plane of a top surface of the top section.

The present inventive concept relates to an oil-water separator for oil-containing residues, including: an outer casing configured to allow residues containing oil and water to be put thereinto; a filter member for separating the oil and the water contained the residues from each other; and a filter support frame coupled to the filter member in such a manner as to be separably seated inside the outer casing, wherein the oil and the water are passed through the filter member at different speeds from each other.
