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.
Abstract:
A filter element is disclosed having at least one mat-type or sheet-type filter web (3), which forms by its outside (5) at least in part a filter jacket (7) that is closed on the peripheral side, wherein along the outside (5) of the filter jacket (7) a surface configuration or modification takes place in such a manner that structures (11) that are delimited from the remaining surface (9) of the filter web (3), are joined to the filter jacket (7) and are of presentable contour and/or thickness are created, wherein the structures (11) are generated by spray-fibre 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). In addition, the production of the filter element and also a shaping device used in this production process are disclosed.
Abstract:
A filter element (1) for filtering fluids, such as hydraulic fluids or gases, is in a filter housing (12) having an inlet (18) for the fluid to be filtered, an outlet (20) for the filtered fluid. The filter element has a data storage (52). Data stored in the data storage (52) is electronically readable from the data storage (52) by a read and/or write device (70). An antenna (60) extends outside the data storage (52) and provides the signal coupling between the data storage (52) and the read and/or write device (70). The antenna (60) extends at least in sections about a longitudinal axis (44) of the filter element (1) such that independently from the angular position of the filter element (1) and the attached data storage (52) a signal coupling between the data storage (52) and the read and/or write device (70) is ensured.
