An apparatus and method are provided for a cone air filter for a closed intake system of an internal combustion engine. The cone air filter is comprised of a cone-shaped filter medium, retained between a base and a cap, that is fabricated to remove contaminants and particulate matter from an intake airstream. The base is comprised of a flange that couples with an air intake duct of the internal combustion engine. A shell receiver is incorporated into the base and receives a rigid exterior shell, such that the exterior shell surrounds the cone air filter and directs the intake airstream therein. A cap is disposed on an apex portion of the cone air filter and is configured to direct the intake airstream around the apex portion and into the cone-shaped filter medium.

According to the present disclosure, air cleaner assemblies, housings, serviceable filter cartridges and features, components, and methods, relating thereto are disclosed. In general, the features relate to systems that are configured to aid in inhibiting an improper cartridge from being installed in an air cleaner housing, during servicing. A variety of features are characterized, and in many examples, the cartridge includes a seal arrangement having radially directed seal surface with at least a first non-wavy or non-projection/recess section and a second wavy or projection/recess section. Examples are shown and described in detail.

A filter element includes a filter body (2) and a monolithic seal (10) arranged to extend circumferentially about the filter body. The seal (10) has a sealing body (14) and a sealing lip (16) which is connected at a first sealing lip section (15) with the sealing body (14) and that is spaced apart from the seating body (14) at a second sealing lip section (17).

A method for producing a filter element provided with a sealing part in which the sealing material is introduced into a casting chamber between two tundish parts when in the non-cured state, and a compensation space connected to the casting chamber for the expansion of the sealing material.

For a method for producing a filter element provided with a sealing part, wherein the sealing material is introduced into a casting chamber between two tundish parts when in the non-cured state, a compensation space connected to the casting chamber is provided for the expansion of the sealing material.

A segmented air filtration element is provided. The segmented air filtration element includes a center tube defining a central axis and an inner passage therein. The center tube includes a plurality of ribs extending along the central axis and spaced apart from one another. A plurality of segmenting surfaces is attached to the center tube in a radial arrangement with respect to the central axis. The plurality of segmenting surfaces is configured to accommodate a plurality of filter media therebetween such that each of the plurality of filter media is selectively replaceable therefrom.

Examples are shown and described in detail.

A filter element for filtering fluid has a fold pack formed of a filter medium folded in a zigzag shape or corrugated shape and provided with fold sections delimited by fold edges. The fold sections include at least two directly neighboring fold sections connected to each other by an adhesive connection of an adhesive material and extending along an adhesive line. The adhesive line extends at least in sections obliquely to the fold edge positioned between the at least two directly neighboring fold sections or the adhesive line extends offset along the fold edge positioned between the at least two directly neighboring fold sections. A filter element with one or more adhesive walls of an adhesive material extending within the fold pack and formed by adhesive connections of directly neighboring fold sections of the fold pack is provided. A method for producing such filter elements is provided.
