Means for filtering a liquid containing various impurities

摘要

The invention relates to means for filtering a liquid containing impurities. Said means comprise a filtering drum (9) rotating within a housing (1) and having around it an annular chamber (13) into which opens a conduit (6) for supplying the liquid to be filtered and a conduit (7) for evacuating the liquid leaving the drum and for cleaning the corresponding section. The lateral wall of the drum (9) is equipped with sliding blades (11) which prevent any and all communication between the two conduits (6) and (7). The filtered liquid is evacuated through the lower wall (9d) of the drum (9) through the lower wall (9d) of the drum (9) through an axial opening. The invention applies in particular to the filtration of fuel for aircraft engines.
