A pleated filter media comprises a plurality of pleats comprised of pleat segments extending in an axial direction between first and second axial ends and extending in a transverse direction that is perpendicular to the axial direction between first and second sets of pleat tips at least partially defined by first and second sets of bend lines. Axial flow channels are defined between the pleat segments in the lateral direction and the plurality of pleats has a width in the transverse direction that varies along the axial direction.

Filter and filter media having reduced restriction

One embodiment is a filter element including an outer filter media and an inner filter media. The outer filter media is operable to remove particulates present in a flow of fluid and/or coalesce water contained in the flow of fluid. The inner filter media is operable to remove particulates from the flow of fluid, separate water form the flow of fluid, and remove particulates from the flow of fluid. Other embodiments include unique apparatus, devices, systems, and methods relating to fuel filters and filtration. Further embodiments, forms, objects, features, advantages, aspects, and benefits of the present application shall become apparent from the detailed description and figures included herewith.

Replaceable filter elements including plural filter media and related filtration systems, techniques and methods

A filter includes a plurality of annular filter elements arranged in axially staggered relation. An axial flow path includes a plurality of flow path segments, some being filtered by a respective filter element, and others bypassing a respective filter element. Various combinations are provided.

Filter with tri-flow path combinations

A filter within a filter cartridge design is described that includes a sealing structure on an endplate of an outer filter element. Generally, the sealing structure includes an annular flange on the endplate that can directly seal against an interior surface of a housing when the filter cartridge is assembled for use. During filtration, the annular flange prevents a working fluid from bypassing the outer filter element. The sealing flange can seal with the housing in a press fit engagement.

An inertial gas-liquid separator removes liquid particles from a gas-liquid stream and has a variable orifice area variable along an axial direction and dependent upon axial movement of a plunger relative to a housing sleeve.

A crankcase ventilation system for an internal combustion engine has a jet pump suctioning scavenged separated oil from the oil outlet of an air/oil separator and pumping same to the crankcase.

A filter assembly, including an air cleaner, has an auxiliary flow component having a mounting flange extending into a gap between a housing port and a conduit in trapped relation to mount the auxiliary flow component to the port and the conduit at the interface thereof. The port and conduit are mounted to each other with the mounting flange therebetween in permanently captured sandwiched relation, without detachment fasteners.

A filter with installation integrity permits fluid flow only in a first installation condition and not in a second undesired or mis-installation condition, including improper alignment or mounting of a filter element in a housing, an incorrect replacement filter element, absence of a filter element, and an incorrect housing cover. A magnetically actuated valve has a piston controlling fluid flow according to installation condition.

Filter with installation integrity and magnetic flow-control

A filter assembly includes a filter element mounted in a housing at a sealing interface provided by an integrally molded seal.

Filter assembly with cost effective seal

A filter includes a housing with multiple flow passages and filter elements providing volume-efficient bottom-in, top-out flow or top-in, bottom-out flow. In another embodiment, parallel filtering flow paths are provided with multiple filter elements having respective overlapped sections axially aligned, with at least one filter element having a radial extension section non-axially aligned with another of the filter elements.
