Abstract (en)
[origin: WO2008116519A1] A filter device with a filter housing (1) having a fluid inlet (11) and a fluid outlet (13), and with a filter element (5) which can be received in the housing (1) and which can be exchanged. The filter element (5) has a first filter medium (27) which surrounds a first filter cavity (51) extending along a longitudinal axis. Fluid to be cleaned can flow from the outer side of the filter medium (27) to the first filter cavity (51). The filter element (5) also has a second filter medium (33) which surrounds a second filter cavity (53) which is coaxial to and lies inside the first filter cavity (51), wherein the second filter cavity (53) can make a fluid connection to the fluid outlet (13) of the filter housing (1). The invention is characterized in that a flow guide unit (57) is provided which forms two separate flow paths for the fluid to be cleaned, the first of which brings the fluid which has passed through the first filter medium (27) directly to the fluid outlet (13) of the filter housing (1), and the second of which connects the fluid inlet (11) of the filter housing to the outer side of the second filter medium (33).
