Abstract
The invention relates to a filtering device for highly viscous fluids, having at least two parallel screen plungers which are arranged in a displaceable fashion in screen plunger bores of a housing and which have in each case at least one screen cavity in which at least one filter element is arranged, wherein the housing has an inflow opening from which, on the untreated side, at least one flow duct leads to each screen plunger bore, and the housing has at least one flow duct which, on the clean side, leads from each screen plunger bore to an outflow opening. On the untreated side and/or on the clean side, in each case one common flow duct leads rectilinearly along both screen plunger bores and, in a production position, tangentially intersects the screen cavities.
