  • Patent number: 10166496
    Abstract: A filter device, in particular for fluids polluted with admixtures of water, such as diesel oil, includes a filter housing (1) having a fluid inlet (43), a fluid outlet (44) and a filter element (9). During the filtering process, the fluid can flow through the filter medium (11) of the filter element from the unfiltered side (14) to the filtered side (13) of the filter medium and into its inner filter cavity (17). On at least one side of the filter medium (11), a water-separating system (23) has a separating region (25) for separated water. The water separating system is connected via at least one water opening (35) that is open toward the separating region (25) to a water collecting chamber (45). The filter element (9) has a passage (29) forming a fluid connection to the inner filter cavity (17) and can be connected to an element receptacle (47) of the filter housing (1). A fluid-conveying system (41) forms fluid paths separated from each other.

  • Patent number: 10080984
    Abstract: A filter device for filtering fluids such as fuels, including diesel fuel, has a filter housing (1), within which a filter element (17) can be fastened and exchanged. The filter element has a filter medium that surrounds an inner filter cavity (25). A fluid inlet leads to the unfiltered side (27) of the filter element (17). A fluid outlet outflows filtered fluid from the filtered side (25). An equalizing tube (49) extends in the filter housing (1) up to a maximum filling level height for the filtration operation. The equalizing tube is connected to a tank return connection at a lower end of the equalizing tube and is open at an upper end (51) of the equalizing tube. The tube (49) has, at distances from the upper and lower ends of the tube, an inner control part (60) with a passage opening (61) forming a throttle point.

  • Patent number: 9962639
    Abstract: A filter element has a mat-type or sheet-type filter web (3) forming by its outside (5) at least in part a filter jacket (7). Along the outside (5) of the filter jacket (7), a surface configuration or modification takes place with structures (11) being delimited from the remaining surface (9) of the filter web (3), being joined to the filter jacket (7) and being of presettable contour and/or thickness. The structures (11) are generated by spray-fiber application and shaping, in such a manner that in time sequence, first the structures (11) and then the filter jacket (7), or in reverse order in time sequence, first the filter jacket (7) and then the structures (11), or that simultaneously both the filter jacket (7) and the structures (11) are formed in negative or positive shape on the filter jacket (7). The production of the filter element and a shaping device used in this production process are disclosed.

  • Patent number: 9751030
    Abstract: A filter, in particular for fluids polluted by admixtures of water, such as diesel oil, includes a filter housing (1) receiving at least one filter element (9). During the filtering process, fluid can flow through the filter medium (11) from the outer unfiltered side (13) of the filter element into an inner filter cavity (17) forming the filtered side (19). A water passage (39) inside a pipe connector (35) of an end cap (23) forms a fluid path (51), which is separated from the other fluid path (55) that forms the connection between the inner filtered side (19) of the filter element (9) and a fluid outlet (37) of the housing (1) in the functional position of the filter element (9). The element receptacle (29) forms a through-passage (59) toward the water collecting chamber (31). Scaling assemblies (83, 87) located between the through-passage (59) and the pipe connection (35) of the end cap (23) delimit a connecting chamber (36) on the outside of the pipe connector (35).
