ABSTRACT:
In a filtering device comprising one or more filtering elements (1) having in principle co-axially disposed through-going apertures (4) for the passage of fluid, the individual filtering element (1) consists of two identical filtering discs (2, 3) which abut each other closely along their outer peripheral edges, and which at the sides facing away from each other are formed in such a way that several filtering elements (1) abut each other closely along the inner edges adjacent to the aperture (4). To obtain a relatively large surface of penetration, a good deep-filtering capacity and a substantially even filtering velocity in principle in the entire filtering device, the filtering discs are corrugated outside the edge areas (5, 6) and simultaneously they are of such a planar shape that the crests at their adjacent sides, between the individual filtering elements (1) as well as between the individual filtering discs (2, 3), abut each other at the intersecting spots, the filtering discs (2, 3) being located relative to each other in such a way that confronting corrugations cross each other.
