摘要： A filter cartridge assembly includes a filter cartridge having a generally cylindrical filter medium which defines a cylindrically shaped core space, and a pair of end caps fixed to opposite ends of the filter medium. Most preferably, the filter cartridge is "coreless" in that it is not provided with an integral support core structure. At least one of the end caps (e.g., the proximal end cap) is annular and has an interior cylindrical surface defining an interior space in alignment with the core space. A truncated generally conically shaped seal skirt is operatively associated with the annular end caps. The filter cartridge is sleeved over reusable support core structure which includes a base having a truncated conically shaped seal skirt, and a tubular perforated rigid core element fixed at one end to the base. The annular end-cap and the base of the support core structure are removably mechanically coupled to one another, most preferably by being threadably interconnected. In such a manner, the seal skirt is sealingly engaged with the seal skirt of the base. The base of the support core structure most preferably is provided with a protruding seat boss which carries seal rings (e.g., conventional O-rings). The seat boss is thereby adapted to being removably, but sealingly, seated within an internal seat cup structure of a conventional filter housing.

摘要： A filter cartridge comprises a length-adjustable end cap attached to an end of a filter body. The end cap includes an annular seal, a spacer coaxially positioned in spaced relationship with the seal, and a connection member including a cylindrical neck in moveable sealing contact within the seal and in a snug sliding fit within the spacer and an imperforate flange including a seal on a radial outer region thereof. A method of joining an end cap to an end of a generally cylindrical filtration medium comprises positioning an annular spacer ring in a recess of a connection flange of an end cap; melting an exposed portion of the connection flange; contacting the melted exposed portion of the flange and an end of a filter body; and allowing the melted exposed portion to cool and bond the filter body to the end cap.
