FLUID FILTER

摘要

A filter for filtering a fluid comprises an inlet end and an outlet end, a distensible member extending longitudinally of the housing, and a plurality of fibres extending longitudinally of the housing and being secured at the inlet end. When the distensible member is distended, the fibres are compressed to form a graduated filter matrix. An additional filter medium is introduced into the inlet end and becomes trapped in the fibres for further filtration of the fluid.
