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. The first fluid path (59/69) leads from the fluid inlet (43) of the housing (1) to the unfiltered side (14) of the filter element (9). The second fluid path (57) connects the respective water opening (35) to the water collecting chamber (45).

Abstract translation: 一种过滤装置，特别是用于混合水（如柴油）污染的流体，包括具有流体入口（43），流体出口（44）和过滤元件（9）的过滤器壳体（1）。 在过滤过程中，流体可以从过滤的侧面（14）流过过滤元件的过滤介质（11）到过滤介质的过滤侧（13）并进入其内部过滤腔（17）。 在过滤介质（11）的至少一侧，水分离系统（23）具有用于分离的水的分离区域（25）。 水分离系统经由至少一个朝向分离区域（25）开放的水开口（35）连接到集水室（45）。 过滤元件（9）具有形成与内部过滤腔（17）的流体连接的通道（29），并且可以连接到过滤器壳体（1）的元件容器（47）。 流体输送系统（41）形成彼此分离的流体路径。 第一流体路径（59/69）从壳体（1）的流体入口（43）引导到过滤元件（9）的未过滤侧（14）。 第二流体路径（57）将相应的水开口（35）连接到集水室（45）。
