ABSTRACT:
Sealing means for use in the upstream passage of a slide plate screen changer, comprising a ring-shaped seal for contact with the slide plate, a pliable ring and a sleeve. A cavity external to the passage is formed by the seal, the sleeve and a shoulder on the body defining the passage. The pliable ring substantially fills and is confined by the cavity. The sleeve forms an aperture communicating between the passage and the cavity to transmit the pressure in the passage to the pliable ring.
