摘要： A filter element including a filter media, a first end cap, and a second end cap is provided. The filter media has first and second filter ends. The first end cap is attached to the first filter end and the second end cap is attached to the second filter end. The second end cap is formed from a molded material and includes a handle structure unitarily molded therein. The handle structure includes a flange with a void formed at least partially transversely therethrough. The void is molded without a mold split such that no mold split parting line is formed on the second end cap. In one embodiment, the void is formed in the flange of the handle structure using a grommet molded therein.

摘要： A method and apparatus are provided, for forming a filter element including a media pack in the form of a coiled fluted filter media, by winding the web of fluted filter media around a pair of tools of a mandrel. The tools engage the sides of the filter media. The tools define a major axis to provide the media pack with a oblong or elongated shape. The web may be fed at constant linear speed, and/or a motor may be controlled in a manner to provide constant driving torque to maintain a constant tension on the web. The winding apparatus and methods may include apparatus or methods to modify the feed path of the web to adjust the tension of the web as it is being wound. Further, the coiled media packs can be fixtured to prevent relaxation. A method may form various shaped media packs with the same apparatus.

摘要： A filter apparatus and method utilize a filter element, defining a longitudinal axis and an axial end thereof, and having a central winding structure and a length of fluted filter material wound about the winding structure with the flutes of the media oriented to provide for filtration of fluid passing axially through the filter element. An edge of filter media defines the axial end of the filter element when the media is wound about the winding structure. An axial end of the winding structure is disposed adjacent the axial end of the filter element. A winding feature extends substantially axially outward from the axial end of the winding structure to a distal end of the winding feature. The filter media is wrapped about the winding structure such that the axial end of the filter element is disposed substantially flush with the distal end of the winding feature.

摘要： A fluid filter includes a base plate, a canister, and filtering media contained in the canister for filtering fluid from an inlet port to an outlet port. Notches are formed into an outer periphery of the base plate. An annular bead of the canister side wall is partially formed into the notches to provide a torque locking mechanism between the base plate and the canister. The terminating lip portion of the canister is wrapped around the outer face of the base plate and formed into an annular trough to directly secure the base plate to the canister. The annular trough includes a diverging outer wall that provides a narrow contact interface between the terminating lip portion and the retention corner of the base plate to thereby reduce moment loads induced therebetween as a result of high fluid pressures in the filter.

摘要： A fluted filter media includes a wall of porous filter material separating a first flute from one or more adjacent flutes, and an intermediate flow restriction disposed in the first flute between upstream and downstream ends of the filter media, so that fluid entering the first flute upstream of the intermediate flow restriction is urged to flow through the wall upstream of the intermediate flow restriction into one or more of the one or more adjacent flutes while flowing through the filter media. Where the adjacent flutes include flow restrictions disposed upstream and downstream from the intermediate flow restriction, the intermediate flow restriction urges fluid flowing through the first flute to pass through the wall at least twice between the upstream and downstream ends of the media. Filter apparatuses and methods incorporating such a fluted filter media having an intermediate flow restriction are also provided.
