The invention relates to an at least two-piece housing (2), in which a first coaxial annular filter element (3) and a second annular filter element (4) are arranged, wherein the annular filter elements (3, 4) are connected in series and therefore flow occurs through same consecutively, - the annular filter elements (3, 4) are configured separately, - a function carrier (6) is provided, which is arranged in the center and inside the annular filter elements (3, 4). In this connection, it is essential to the invention that the function carrier (6) is configured as a one-piece, rod-shaped plastic injection part and which has three separate channels (7, 8, 9) for guiding the three different fluids, wherein the first channel (7) has a radial inlet (10), an axial outlet (11) and a U-shaped deflection (12). ***** |
