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). The connecting chamber connects the other fluid path (55) to the fluid outlet (37) of the housing (1).
