Self cleaning liquid strainer

Abstract

Abstract An inwards flow cylindrical strainer conventionally formed of a spiral of notched wire is enclosed in a shell which divides the liquid flow into several parallel helical paths round the outside of the strainer cylinder. Part of the flow passes inwards to the filtrate outlet, the remainder flushes the surface and is recirculated back to the unfiltered oil reservoir. When in spite of the flushing the strainer becomes clogged to the extent that the differential pressure rises above a predetermined level, the liquid valves are automatically closed and air or gas is blown backwards through the strainer from the clean side to dislodge the obstructions.
