摘要： A filtering device for thermoplastic synthetic material has a filter support (3) with at least one filter (9) longitudinally movable in a casing (1). In the flushing position of the filter support (3), this filter is in communication with a flushing channel (8) for back-flushing purposes. In order to make the rinsing process rapid, effective and uniformly distributed over the surface of the filter and to prevent additional loss of mass in the mainstream during back-flushing, there is a reservoir (15) in the filter support (3) which is filled with clean molten material during normal operation and in which a piston (20) can move by means of which the molten material (15) in the reservoir is forced through the filter (9) and into the flushing channel (8) in the back-flushing direction.

摘要： Un dispositif de filtrage de matériaux synthétiques thermoplastiques comprend un support (3) de filtre mobile dans le sens de la longueur, dans un boîtier (1), et au moins un filtre (9). Pour que ce filtre puisse être lavé à contre-courant dans la position de lavage du support (3) de filtre, il est en communication avec un canal de lavage (8). Afin d'assurer un lavage rapide, efficace et uniformément réparti sur la surface du filtre, tout en évitant une perte additionnelle de la masse dans le courant principal pendant le lavage à contre-courant, une chambre d'accumulation (15), qui se remplit de matière fondue nettoyée pendant le fonctionnement normal, est ménagée dans le support (3) de filtre. Un piston (20) mobile dans cette chambre d'accumulation (15) presse la matière fondue contenue dans la chambre d'accumulation à contre-courant à travers le filtre (9), dans le canal de lavage (8), lorsque le support de filtre (3) est dans la position de lavage à contre-courant.

摘要： The invention relates to a filtering device (100) for high-viscosity fluids, having 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) comprises at least one inner fluid line (42), which extends from an inlet opening (41) to an outlet opening (43) on the circumference. The outside 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 the outlet opening (43) of said displacing piston in front of the opening of the discharge channel (33) into the partial channel (34, 35) and can be pulled back to a backflushing initial position within the partial channel (34), wherein along a backflushing displacement path, the opening 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).
