Abstract
The invention relates to a filtering device (1) comprising a tubular filter (6). One end of said filter is supported on a base part (2) and the other end is supported on a cupped filter housing (3). The filter housing overlaps the filter (6) with a radial clearance (7) and is detachably connected via the edge (4) thereof to the base part (2). The base part (2) comprises a first flow-through channel (33) which is connected to the clearance (7) and comprises a second flow-through channel (34) which is connected to a cavity (35) of the filter (6). The aim of the invention is to make it possible to attach or detach the filter housing (3) even when tight spatial relationships are present in the vicinity of the filter housing (3) or in order to hold the filter (6) in position against the filter housing (3).
