The present application shows a filtration system comprising a plurality of filters, in particular oil or fuel filters, a first operating element movable from a default position to a least one isolating position for isolating at one filter of a first group of filters from the filtration system and a second operating element movable from a default position to a least one isolating position for isolating at least one filter of a second group of filters from the filtration system. The filtration system comprises a mechanical blocking mechanism that is actuated by a movement of the first operating element out of its default position to block the second operating element in its default position and actuated by a movement of the second operating element out of its default position to block the first operating element in its default position.

A filter assembly for fluidic connection at a function port includes a connection base having a base inlet and a base outlet, the base inlet being fluidly connected to supply channels for supplying a fluid to cartridge inlets of at least two filter cartridges, and the base outlet being fluidly connected to discharge channels to discharge the fluid from cartridge outlets of the filter cartridges. The connection base with the base inlet and the base outlet has a fluidic connection structure corresponding to the filter cartridge with the cartridge inlet and the cartridge outlet such that the connection base or a filter cartridge is fluidly connected at the function port.

The invention relates to a filter unit, a filter system (44b) with at least two filter units, and to a motor vehicle with a filter system (44b). A filter bowl (12d-e) of the filter unit is formed by a base and a cover. Embodied in a side wall of the base are at least two access openings to an antechamber or collection chamber (34a-b) in the filter bowl (12d-e). Embodied integrally with the cover is a collection line segment or supply segment (26d-e) that leads from a clean chamber or an unfiltered side antechamber in the filter bowl (12d-e) to at least two open ends (28l). The inventive filter system (44b) has at least two inventive filter units, and fluid may flow through their filter elements (30, 30a-d), which are switched in parallel. The invention facilitates the space-saving arrangement of filter units and filter systems (44b) in constricted and/or complexly shaped installation spaces, especially in motor vehicles.

A filter assembly for a fluid to be filtered, in particular fuel or oil, has a filter housing having a housing lower part that is configured as a single piece and has at least one fluid inlet for the fluid to be filtered and a plurality of filter pots that are arranged next to one another side by side in a shared plane and are fluidically connected to one another via side wall passages An upper housing part closes the filter pots and has a fluid manifold that has at least one fluid outlet for the filtered fluid flowing out from the filter pots. At least two filter elements, one being arranged in each of the filter pots of the filter housing. The filter assembly is a more inexpensively-manufactured and as configured for installation even in confined installation spaces, so as to accommodate a sufficiently large filter surface for a predetermined volume flow of a fluid to be filtered.

A method of packaging a filter media that is pre-folded for insertion is a filter assembly is provided.

Disclosed herein is a refrigerator, and more particularly, to a refrigerator including a water supply system. The refrigerator includes a main body including a storage compartment, and a water supply assembly disposed in the storage compartment. The water supply assembly includes a first filter mounting portion provided to allow a first filter to be mounted thereon, and a second filter mounting portion provided to allow a second filter to be mounted thereon, and including a residual water guide configured to guide residual water in the second filter mounting portion to the first filter mounting portion.

A blood filtering device comprises a casing defining a containment volume and provided with at least a first inlet for the venous blood, at least a second inlet for the intracavitary blood, at least a third inlet for the extra cavitary blood and at least an outlet mouth for the blood; blood filtering means which are housed inside the containment volume and delimiting at least one filtering volume communicating with the blood inlets and at least one collecting volume communicating with the outlet mouth; where filtering means comprise: at least a first filtering element defining a closed profile and delimiting a first filtering volume communicating with the first inlet; at least a second filtering element defining a closed profile and delimiting a second filtering volume communicating with the second inlet; at least a third filtering element defining a closed profile and delimiting a third filtering volume communicating with the third inlet.

A disposable filter capsule for a filtration device comprises only one housing, which has an inflow connection for a fluid to be filtered and an outflow connection for filtrate. The disposable filter capsule also comprises at least two separate filter means, which are fixed in the housing and together with the housing form an inseparable structural unit. All the components of the disposable filter capsule consist of sterilizable, in particular gamma-sterilizable, materials.
