Abstract
A filter bag assembly includes an outer bag having an open end, a closed end opposite the open end, and a longitudinal axis. The open end of the outer bag is sized and shaped for receiving liquid to be filtered. A filter member is loosely mounted in the outer bag and has a pair of opposed open ends and a plurality of longitudinally extending pleats. Each of the pleats projects generally outwardly in a radial direction.

A filter bag assembly comprising an outer bag including an open end and a closed end opposite said open end and having a longitudinal axis, said open end being sized and shaped for receiving liquid to be filtered;
- and a filter member mounted in said outer bag and having a pair of opposed open ends and a plurality of longitudinally extending pleats, each of said pleats projecting generally outwardly in a radial direction;
- an inner sleeve disposed inside said filter member, said inner sleeve including a cover portion for covering one of the open ends of said filter member proximate the open end of said outer bag, wherein said inner sleeve and cover portion are constructed as a filtering layer;
- and a ring including a skirt attached to said open end of said outer bag and to a radially outer periphery of the cover portion of said inner sleeve, for supporting said filter bag assembly from an internal shoulder of a filter housing.
A filter bag assembly comprising an outer bag including an open end and a closed end opposite said open end and having a longitudinal axis, said open end being sized and shaped for receiving liquid to be filtered;
- and a self-supporting filter member having a generally cylindrical shape, said filter member mounted loosely in, and substantially coaxial with respect to, said outer bag and having a pair of opposed open ends and a plurality of longitudinally extending pleats, each of said pleats projecting generally outwardly in a radial direction and extending between said open ends of said filter member, said filter member including a plurality of tags for maintaining its pleated construction, each of said tags extending from an outer side of one of an adjacent pair of said pleats, penetrating through said one of said adjacent pair of said pleats and terminating at an inner side of the other one of said adjacent pair of said pleats.
