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...
[ I claim:] [1.] A filter changer for a fluid, comprisinga pair of members having opposed, generally conforming surfaces,gap forming means adapted to connect said members rigidly to form a predetermined adjustable space between said surfaces, said members respectively forming upstream and downstream passages extending transversely of said surfaces and a filter aperture communicating between said passages, said members respectively having spaced parallel slide surfaces defining a filter channel extending transversely of said passages through the filter ap...
