Embodiment Construction

[0025] figure 1 A filter element 1 according to an exemplary embodiment of the invention is shown. The filter element 1 comprises a filter body 2 and an annular closure cap 3 . The closure cap 3 is arranged at the axial end of the filter body 2 , wherein the filter body 2 has a hollow-cylindrical shape, which is designed here as a cylinder. Accordingly, all directional statements regarding the hollow cylinder are indicated below.

[0026] Furthermore, the filter element 1 has an additional second closure cap 17 which is arranged axially on the end of the filter body 2 opposite the closure cap 3 . The additional second closure cap 17 is not considered further within the scope of the present invention. In particular, it is only provided that the additional second closure bell 17 is annular and has an inner diameter which at least corresponds to the largest inner diameter of the closure bell 3 . In the exemplary embodiment shown, the filter element 1 has no support tube in th...

Description

technical field [0001] The invention relates to a filter element which can be used in particular in liquid filters, for example in fuel filters or urea filters. Background technique [0002] Liquid filters, in particular urea filters, are known from the prior art. These liquid filters are usually made of unstable materials such as paper. The filter body generally has a hollow cylindrical shape and is provided with a closure cap. If the filter is used, for example, on a vehicle, the filter is located inside a housing, wherein the enclosure seals the filter relative to the housing so that liquid can reach the filter in the inner space of the filter body for subsequent filtration through the filter body in order to exit the housing again on the circumference. [0003] If the filter is to be removed from the housing, there is the risk that the filter body is damaged and broken, so that only a part of the filter can be removed. The parts that remain in the housing must then b...
