Abstract: A connecting element (1) for connecting at least two end portions (2A, 3A) of a flat filter medium (2, 3) has at least three legs (1A, 1B, 1C), one end portion (2A, 2B) each being introducible between two legs (1A, 1B, 1C). Under the influence of heat it is possible to connect the material of the legs with the material of the filter medium (2). The connecting element (1) can be used in a filter element (4) and in particular in a filtering device (5), for example an operating fluid filter for a motor vehicle. The object of a method for connecting at least two end portions (2A, 3A) of a flat filter medium (2, 3) is that the end portions (2A, 3A) are introduced between two legs (1A, 1B, 1C) each of a corresponding connecting element (1) and that through heating the material of the legs is connected with the material of the filter medium (1).

Abstract: A generally cylindrical filter element incorporating nonsymmetrical or asymmetrical V-pleated media. The V-pleated media provides increased filter media per given filter volume, extended filter life, and a smaller filter for equivalent filter life. A smaller filter is generally beneficial for some applications such as aircraft, due to its lower weight. Various features of the filter include asymmetric variable pleat heights applied to a cylindrical or obround filter; defined pleat spacing applied to a variable pleat height element; optimal pleat density; and optimal shape of inlet and outlet.

Abstract: A fluid filtering apparatus and method may include keyed components to ensure that a correct filter element is being installed into a filter base, and to automatically actuate a fluid valve as the filter element is rotated into place on the base. Tool-less replacement of the element is provided. An embodiment of the element may include inner and outer substantially tubular-shaped media packs disposed about an axis, with one end of each of the inner and outer media packs being attached to an end cap of the element in a manner defining a fluid flow space between the inner and outer media packs for receiving a flow of fluid directed in parallel through the inner and outer media packs. A housing of the filter apparatus may include a flow tube configured to fit into the space between the inner and outer media packs.

Abstract: A filter for a fluid system includes a housing having an interior cavity. A filter media is disposed in the housing and defines a central opening. A center tube assembly is arranged within the central opening and includes discs which are stackable upon one another. Each disc includes a central portion having base received by an inner wall of the central portion of the adjacent disc. An outer portion extends radially outwardly from the central portion and is positioned adjacent to the filter media. The central portion, base, and outer portion may include openings to permit the flow of fluid through the center tube assembly. The center tube assembly provides the desired structural integrity while permitting fluid to flow through the center tube. The present invention center tube assembly may be produced by a plastic molding process.
