As shown in Figures 2 and 4 these filtering means comprise a plurality of radial ribs 50 arranged on the plate 20 and projecting axially from the side opposite the tank 8.

• the ribs 50 form a large filtration surface. When the water level is located above the flange 16 and below the plate 20, therefore between the level NI and the level N2, the water flows laminarly between the flange 16 and the plate 20 and is discharged through the inlet 12. In this operating condition, the discharge openings 26 and the ribs 50 are not in contact with water.
