Abstract:
A device for the simultaneous transmittal and filtration of fluids comprising a filter element and a tubular conduit defining an axial path, said filter element and said conduit comprising an assembly, said conduit having a length with a substantially uniform interior dimension, said filter element contained within said length and positioned to entirely transect a first portion of said axial path and further comprising a plurality of regions, said regions having varying density in a radial direction with respect to one another, and said filter element being resilient in a radial direction, said filter element having a maximum circumferential dimension greater than the circumferential dimension of said conduit whereby said filter element engages the interior sidewall of said conduit in frictional engagement in such a manner to allow for the movement of said filter within said conduit in an axial direction in response to fluid flow and to retain said filter element when said filter element is subjected to gravitational force.
