摘要： A filtering device (100) for highly viscous media comprises at least one screen plug (10) which is movably arranged in a screen plug bore (27) of a housing (20) and which has at least one screen cavity (11, 12), a filter element (11.7) lying in said screen cavity. The screen cavity (11, 12) narrows to a funnel section (11.6) in a rear region when viewed in the flow direction, said funnel section opening into at least one screen plug outlet channel that opens upstream of the housing outlet channel (24, 25) in the production position. According to the invention, the screen plug outlet channel comprises an inlet zone (11.1, 11.2), at least one deflecting point (11.3), and an outlet zone (11.2, 12.2). The intake zone (11.1, 12.1) extends from an edge region of the funnel section (11.6), and the outlet zone (11.2, 12.2) is designed as a groove that extends on the outer face of the screen plug (10, 10′) and/or on the inner face of the screen plug bore (27).

摘要： The present invention relates to a filtering device for fluids, in particular thermoplastics, comprising a screen carrier (2) which has a rotationally cylindrical outer face (41) and is mounted rotatably in a rotationally cylindrical recess (5), adapted to its circumference, of a stationary housing (3) and in which a number of screening nests (6) having filter arrangements (7) are formed along its circumference. According to the invention, there is provision whereby the screen carrier (2) is penetrated by a rotationally cylindrical core part (1) and is mounted rotatably on this, the core part (1) and the housing (3) being designed to be stationary and fixed in terms of rotation with respect to the rotatable screen carrier (2).
