Abstract:
The invention relates to a filter device, in particular for fluids polluted with admixtures of water, such as diesel oil, comprising a filter housing (1) which has fluid connections in the form of a fluid inlet (51) and a fluid outlet and in which at least one filter element (9) can be received. During the filtering process, fluid can flow through the filter medium (11) of the filter element from the unfiltered side (13) to the filtered side (19) of the filter medium, which surrounds an inner filter cavity (17). On one side of the filter medium (11), a water-separating device (26) and a separating region (27) for separated water are present, and the filter element (9) has a passage (43) that forms a fluid connection to the filter cavity (17) and at least one water opening (47) that is open toward the separating region (27). The filter element can be fixed to an element receptacle (29) of the filter housing (1) and can be connected to a water collecting chamber (33). The filter device is characterised in that an adapter part (49) is provided at least as part of a fluid-conducting system, in which fluid paths separated from each other are formed, of which the first fluid path (59, 67, 61) leads from a fluid connection (51) of the housing (1) via the passage (43) to the inner filter cavity (17) of the filter element (9) and the second fluid path (69) connects the respective water opening (47) to the water collecting chamber (33).
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.

Abstract:
The invention relates to a filter device, in particular for fluids contaminated with water admixtures, such as diesel oil, comprising a filter housing (1), which can hold at least one filter element (9), the fiber medium (11) of which separates an untreated side (13) from a treated side (19) during the filtration process in the filter housing (1), wherein a water collecting unit (5) is provided, which holds separated water on the treated side, wherein said filter device is characterized in that water that has been separated on the untreated side (13) also reaches the collecting unit (5) and in that mutually separated collecting chambers (61, 67) are present in the collecting unit (5) for the water that is discharged both at the treated side (19) and at the untreated side (13).
Abstract:
The invention relates to a filter, in particular for fluids polluted by admixtures of water, such as diesel oil, comprising a filter housing (1) in which at least one filter element (9) can be received. 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). The filter is characterised in that 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 filter is further characterised in that the element receptacle (29) forms a through-passage (59) toward the water collecting chamber (31), and scaling assemblies (83, 87) located between the through-passage (59) and the pipe connection (35) of the end cap (23) de-limit a connecting chamber (36) on the outside of the pipe connector (35). The connecting chamber connects the other fluid path (55) to the fluid out-let (37) of the housing (1).
Abstract:
The invention relates to a device (2) for purifying water (6, 9) contaminated with organic substances, that is drained or collected from filters, especially fuel filters (4) or elements of a fuel system. Said device is characterised in that hydroxyl radicals are formed from the water (6, 9) by means of a separating device (8), said hydroxyl radicals oxidising the impurities, especially organic substances, as much as possible, and converting them into compounds such as CO2.
