Abstract: A method and apparatus for separating particles from liquids is disclosed. The apparatus comprises a generally cylindrical swirl chamber with a generally axially symmetric shape, and a porous filter element positioned coaxially inside the swirl chamber. The porous filter is preferably composed of a plurality of porous tubes. The liquid to be treated is forced into the swirl chamber through tangential injection slits extending along most of the height of the chamber, which generate a vortex flow inside the swirl chamber and around the porous filter element. Particle-free liquid permeates across the porous filter, flows along its interior, and is collected at a filtrate outlet port. The remaining liquid, now having a higher particle concentration, flows out of the apparatus and can be separately collected, or recirculated back to the apparatus for further separation. The swirling flow retards particle motion toward the filter element thus minimizing buildup of a cake of particles on the porous filter medium.

Abstract: A filter element for a fuel filter includes an outer, coalescing filter media and an inner, water-absorbing filter media. The outer media normally filters or separates particles from the fuel system and coalesces water in the fuel. As the outer media degrades through use and water penetrates to the inner media, the inner media absorbs the water to act as a back-up for the outer filter media. As the inner media absorbs water, the inner media expands to restrict the fuel flow therethrough. At a predetermined pressure differential across the inner media, a by-pass device in the inner filter media opens or otherwise allows fluid from the outer filter media to bypass the inner filter media. Although the by-pass device provides a fluid path around the inner media, the outer media maintains its particle filtration efficiency of the fuel at a high level.
