Plate-filtering device for filtering plastics melts, has sleeve movably arranged in front housing part, and pressure absorption section formed in sleeve within thin opening width of sealing ring and projected into flow channel

摘要

The device (10) has a sleeve (3) movably arranged in a front housing part (7) and pressed into a movable plate (4) and a filter insert (5). A funnel surface (3.2) is formed at a side associated to the filter insert. A sealing ring (2) is arranged between the sleeve and a safety ring (1). The sealing ring has a chamfer conical surface (2.1) and a front surface (2.2) that is aligned perpendicular to a flow direction. A pressure absorption section (3.1) is formed in the sleeve within a thin opening width of the sealing ring and is projected into a flow channel (8).
