초록

A sealing device for sealing a slide plate in a polymer filtration apparatus where the slide plate is translatable across an extrusion bore extending through a housing of the polymer filtration apparatus. A spring device can be positioned around the outer periphery surfaces of the seal for axially biasing the sealing surface of the seal against the slide plate with a preload bias. Increasing pressure of polymer in the extrusion bore can enter a region in the seal cavity upstream of the thrust surface of the seal and can provide polymer pressure in the ax...
