ABSTRACT:
A filter assembly is formed by arranging a large number of substantially annular, thin filter elements disposed around a radially pervious and hollow core so that a major portion of the core is surrounded by the filter elements. Slots between the filter elements allow passage of the liquid to be filtered. The filter assembly is enclosed in a closed vessel with the interior of the core being in communication with an outlet line. An initial axial pressure is established on the filter elements by a spring which acts on an end support engaging the end one of the filter elements. The axial pressure on the filter elements is controlled by controlling pressure in the closed vessel and thus the size of the slots is controlled to establish the desired filtering degree of the filter assembly.
