摘要： A filtering device (100) for high-viscosity fluids has a partial channel (34) in the housing (30) and a displacing piston (40) which can be inserted into the partial channel (34, 35). The displacing piston (40) has at least one inner fluid line (42) that extends from an inlet opening (41) therein to an outlet opening (43) on its circumference. The outer diameter of the displacing piston (40) corresponds to the inside diameter of the partial channel (34, 35). The displacing piston (40) can be positioned, in a production position, with its outlet opening (43) in front of the inlet of the discharge channel (33) into the partial channel (34, 35) and can be retracted to a backflushing initial position within the partial channel (34). Along a backflushing travel path of the displacing piston, the inlet of the discharge channel (33) into the partial channel (35) is covered by the outer wall of the displacing piston (40) and/or the outlet opening (43) of the displacing piston (40) is covered by the inner wall of the partial channel (34).

摘要： A device for filtering a liquid synthetic material. The device has a housing, a feed channel, a discharge channel, and backflow channels. The feed duct is subdivided into split-feed channels (2A, 2B). The cross-section of the orifice of the split-feed channels, where they open into the filter chambers, is smaller than the normal cross-section of the feed channels.

摘要： A plate filtering device (10) for plastic melts has at least two stationary housing components (7, 9) with a movable plate (4) with a filter insert (5) disposed between them. A locking bushing (6) that extends up to the movable plate is placed at the downstream housing component (9), and its inner recess forms a part of the flow channel. A seal bushing (3) that can be pressed against the movable plate (4) and/or the filter insert (5) is located in movable fashion in the front housing component (7). A funnel area (3.2) is formed on the side facing away from the filter insert (5). A sealing ring (2) is located between the sealing bushing (3) and a retaining ring (1). The sealing ring exhibits at least one angled conical surface (2.1) and one face area (2.2) that is oriented at a right angle to the direction of fluid flow. At the seal bushing (3), an effective pressure area (3.1, 3.1′, 3.1″) that extends into the flow channel (8) is formed within the inner width of the sealing ring (2).
