Abstract
A slide plate filter changer having an upstream seal ring bearing on the filter carrier in the operative position to prevent fluid leakage into the filter carrier channel. The seal ring is subjected to bimodal longitudinal forces respectively produced by screws adjustably bearing on tapered surfaces of the seal ring and the pressure force of the fluid resulting from the difference between the upstream and downstream effective surface areas of the seal ring.
