    摘要： The invention relates to a filter device for fluids, in particular in the form of a tank-installation return filter, comprising at least one filter element (27), which can be accommodated in a housing (3), which has a fluid inlet (17) for supplying unfiltered fluid to an inner cavity (31) of the respective filter element (27), which inner cavity is surrounded by a filter medium (29) through which unfiltered fluid can flow. The filter device is characterized in that a flow-conducting apparatus (13, 49, 77) that orients the flow of the unfiltered fluid reaching the filter medium (29) is provided between the fluid inlet (17) and the inner cavity (31) of the respective filter element (27).
