Filtering device for high-viscosity fluids

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...

Zusammenfassung:	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).
