ABSTRACT:
A continuous flow filter changer for a fluid having a filter carrier assembly for intermittent sliding transition displacements in a filter channel to align adjacent filters thereon successively with a filter aperture in the flow passage. The duration of each such transition is substantially less than that between transitions. A ring shaped seal sealingly connects between the flow passage upstream thereof and a filter aligned with said aperture to prevent fluid flow except through said filter. The clearance for sliding between the filter carrier assembly and the filter channel is controlled to allow for such displacements while limiting the fluid leakage from the filter channel during a single transition to a predetermined level.
