Abstract
A fluid filtering device for use with a filter body having a chamber open at one end and a fluid inlet and a fluid outlet port in fluid communication with the chamber. The device comprises a housing formed by molding a plastic cap onto one axial end of a tubular cage. A filter element is disposed within the cage while an annular member is nondetachably secured to the other end of the cage to entrap the filter element within the cage. The cage is dimensioned so that upon insertion into the body chamber, the filter element is positioned between the inlet and outlet ports while the cap covers the open end of the chamber. In addition, a fluid bypass valve is contained within the cage and bypasses the fluid flow around the filter element from the fluid inlet to the fluid outlet upon the occurrence of a predetermined differential pressure across the filter element.
