METHOD AND APPARATUS OF A FLUID FILTERING SYSTEM WITH COMPRESSED BLOCKING AREA

摘要

The present invention typically involves the use of a compressed blocking ar ea (34) to assist in sealing a filter element (21a) and avoiding channeling in a wound fibrous tissue filtering system. It may involve the use of multiple, spaced, interstitial rings. It may involve the intentional wasting of a portion of the filter element to create a compressed blocking area (34). It may also involve the use of different heights of the rings and may include t he use of compression and secondary tapers (40) on the rings. The heights and spacing of the rings with respect to the other ring or rings may vary in a certain ratio.
