Abstract
A fluid collector for use in a fluid filter includes a substantially flat portion having two sides of which at least one faces a filter element from which filtered fluid is received, a centrally disposed opening adapted to allow the centrally located flow path to pass axially therethrough, and at least one slot which forms a passageway for filter fluid to flow from the filter elements to the receiving ports into the centrally located flow path. The fluid collector also includes ridges which project axially from at least one side of the substantially flat portion to maintain the filter element ends in parallel spaced relationship to the substantially flat portion. The filter collector further includes a continuous annular ring portion which projects axially from the outer perimeter of the flat portion on at least one side thereof to extend into each adjacent filter element exit end between those layers of filter element tissue which are located inwardly a few layers from the periphery of each filter element, so that a seal is formed which separates filtered fluid from unfiltered fluid.
