A filter arrangement for extracting solid particles from flowing liquid comprises a filter housing (1), at least one tubular filter (2) mounted in the housing so that the liquid will pass through the wall of said filter, and a liquid inlet and liquid outlet (4, 5) respectively. According to the invention, the mutually opposite ends of the filter or each filter are free or exposed and disposed so that liquid will flow simultaneously through both ends. The filter or filters (2; 2A) is/are surrounded by an inner casing (3) which is mounted in the filter housing spaced from the walls thereof and which leaves the mutually opposite ends of the filter or filters free. The interior of the inner casing is connected to either the inlet or the outlet (4, 5) while the space between the filter housing (1) and the inner casing (3) is connected to the other of said inlet or outlet. |
