摘要： An air filter element having an inner metal liner, an outer metal liner, a filter media, an annular end cap, and a composite end cap is provided. The annular end cap is formed over the metal liners such that the metal liners are secured and at least a portion of the filter media is sealed. The composite end cap has an annular plastic insert and a foamed urethane portion. The annular plastic insert is tapered upwardly from an outer insert periphery toward a central aperture. The foamed urethane portion is molded about the annular plastic insert such that the metal liners are secured, at least a portion of the filter media is sealed, and an annular groove is formed on an underside of the composite end cap. The annular groove has a plurality of transverse ribs therein. Urethane flashing occurs proximate the central aperture and/or the outer liner periphery.

摘要： A method and apparatus are provided, for forming a filter element including a media pack in the form of a coiled web of fluted filter media, by feeding the web of fluted filter media at a controlled linear speed onto a mandrel rotated by a winding motor providing a controlled driving torque to the mandrel, to thereby maintain a controlled tension on the web of fluted filter media as the web is would onto the mandrel. The web may be fed at a substantially constant linear speed to the mandrel, and/or the winding motor may be controlled in a manner providing substantially constant driving torque to the mandrel for maintaining a constant tension on the web as a function of the constant driving torque. Coiled media packs having circular or non-circular cross sections, can be formed with either cored, or core-less construction.

摘要： A filter element for filtering fluids and gasses flowing through a filter housing is provided. The filter element includes a permeable filter media for filtration of contaminants and a rigid frame for supporting and retaining the filter media. To ensure that gasses and fluids flow through the filter media rather than around the filter element, a resilient seal element is attached along an outer peripheral surface of the frame. The seal element can be resiliently compressed between the inner surface of the filter housing and the outer peripheral surface to create a sealing effect therebetween. To prevent the filter media from interfering with the seal element, the filter media is substantially constrained within the outer peripheral surface of the frame.

摘要： Filter elements and filter systems are provided. The filter element allows for a reversed flow of fluid through the filter element when flowing from a first port to a second port of a filter head of the filter system. The filter element includes a standpipe in a central cavity of a tube of filter media that is fluidly connected with an exterior of the tube of filter media by a radial flow conduit and an axial flow tube.

摘要： A filter element for use in a housing of a filter assembly having a cover and a seal therebetween. The housing includes inlet and outlet valves. The filter element comprises a first endcap and a second endcap including an inlet valve actuator. A cylindrical ring of filter media extends axially between the first and second endcaps and surrounds a center tube that defines an outlet having an outlet valve actuator. A sleeve positioned to receive and exert force in a first and second direction surrounds a bias member. Threading the cover to the housing compresses the bias member causing the inlet and outlet valve actuators to actuate the inlet and outlet valves. Removing the cover causes extension of the bias member and the inlet and outlet valve actuators to retreat from the inlet and outlet valves before the seal between the cover and the housing is broken.

摘要： A filter base cap for sealing and protecting a filter base once a filter has been removed for storage, shipping and transporting of a mechanical system is provided. The filter base cap attaches to the filter base of the system to prevent leakage of residual fluid within the system, such as an engine or other device, after the system has been tested. The filter base cap will provide fluid circulation in the event the mechanical system is started prior to replacing filter base cap with a filter that would otherwise provide fluid flow to the mechanical system.

摘要： Filter media, filter elements, and method of forming filter media and filter elements are provided. The filter media and filter elements require filtered fluid to pass through filter media twice. The filter media and filter elements generally relate to fluted or similar style filter media. The filter media is formed from convoluted sheets coupled to face sheets to form first and second sets of flutes. At least one of the flute sets includes inlet and outlet seals and the other one of the flutes includes an intermediate seal interposed between the inlet and outlet seals of the other flute set. This forces the fluid to pass through the filter media at least twice.

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.
