摘要： A filter device has a filter housing (2) and a filter element (15) accommodated in the filter housing. The element material (44) of the filter element for filtering a liquid extends between two end caps (40, 42). At least one end cap (40) is mounted on an element receptacle (14). A bearing (46, 54), providing more than one degree of freedom, is used to articulate the filter element (15) on the element receptacle (14) via its one end cap (40). The bearing has a convex bearing surface (46) that is guided in a concave bearing surface (54). The respective bearing surface (46, 54) is part of a respective shell (55a, 55b). At least one shell (55b) has a passage (55c) for liquid media.

摘要： The invention relates to a filter cartridge for insertion in a filter housing of a fluid filter, comprising: a filter material configured to filter a fluid flowing therethrough from a raw side to a clean side of the fluid filter during operation of the fluid filter; and a filter-cartridge-side radio module configured to move, during operation of the fluid filter, according to the pressure difference between the raw side and the clean side of the fluid filter, which pressure difference depends on the degree of contamination of the filter material, and to communicate, in order to ascertain the degree of contamination of the filter material, with a housing-side radio module of the fluid filter, the distance (A) of which housing-side radio module from the filter-cartridge-side radio module varies upon movement of the filter-cartridge-side radio module.

摘要： An inline reductant filter assembly includes a filter housing, a filter media, and one or more valves. The filter housing is fluidly coupled to an upstream portion of a reductant line and a downstream portion of the reductant line. The filter media is positioned in the filter housing. The one or more valves are selectively movable from a first position to a second position. In the first position, the one or more valves permit fluid to flow along a first fluid flow path from the upstream portion of the reductant line, through the filter media, to the downstream portion of the reductant line. In the second position, the one or more valves prevent fluid from flowing along the first fluid flow path through the filter media.

摘要： A water filter assembly for a refrigeration appliance and an arcuate body for a water filter assembly are provided. The arcuate body includes a body forming an arcuate section. A pin extends along a longitudinal extension of the body and is configured to contact a bypass valve to close the bypass valve when the arcuate body is positioned within a chamber at the water filter assembly. The water filer assembly includes a filter body separable from the arcuate body.
