<p>Liquid filter arrangement (2) with interchangeable filter element (32) and including a pot-like filter housing (4) in which the filter element is disassemblably inserted between a liquid inlet (28) to the chamber and an outlet (30) situated below, in the lower section (16) of the filter housing, for filtered liquid from the chamber (6). In the liquid chamber (6) is arranged a central tube (22) about which is arranged the filter element (32) which is provided at the bottom with an annular end piece (34) sealingly surrounding the central tube, and is provided upwards with an end disc (36) by which the filter element is fastened to a lid (14) fastened sealingly in the upper section (12) of the filter housing (4). When the filter element (32) is in its fitted position, the end piece (34) blocks the inlet to a draining duct (64) in the central tube (22), which leads to a draining outlet (68) from the chamber (6). The inlet to the draining duct is so placed relative to the end piece (34) and the lid (14) that as the filter element is taken out of the chamber the duct inlet is freed and opened before the sealing effect between the lid and the filter housing ceases.</p> |
