  • Patent number: 5486290
    Abstract: In an axial flow fluid filter having two filter elements formed of layers of tissue wound around a central core, a fluid collector is positioned between two filter elements and has a central annulus which surrounds an axial flow path. The central annulus has a top surface perpendicular to the flow path. A rim annulus and a plurality of annular ribs have top surfaces coplanar with the central annulus which engage with an upper filter element. A plurality of radial ribs extend axially from the annular ribs and engage with a lower filter element. The annular ribs define axial fluid flow passages and the radial ribs define radial flow passages which direct filtered fluid into the central flow path. The fluid collector is formed as a unitary plastic injection-molded part which rigidly spaces apart two filter elements and which directs fluid flow to the outlet port of the fluid filter with minimal flow obstruction.
