Publication number: 20230018748Abstract: Embodiments described herein relate generally to filter assemblies that include filter elements with cross-channel flow having flat and/or folded arrangements for optimized functionality and performance. The filter assemblies may be formed (e.g., shaped, constructed, etc.) using a variety of shapes, angles, configurations, and materials to improve the filtration and cross-channel flow of fluid through the filter media. The filter media may implement a wide variety of patterns (e.g., repeating, origami, rounded, etc.), shapes (e.g., tetrahedral, rhombus, square), and construction (e.g., pleated, integrated, interdigitated, etc.).Type: ApplicationFiled: December 9, 2019Publication date: January 19, 2023Applicant: Cummins Filtration Inc.Inventors: Mark P.

Patent number: 10821385Abstract: Filter housings that have housing wall surface irregularities are described. The surface irregularities are positioned on the inner walls of the housings and/or axial ends of the housing walls. The surface irregularities may be, for example, grooves, ribs, bumps, and the like. The surface irregularities provide an engine integrity protection (EIP) feature by preventing non-approved replacement filter elements from forming seals against alternative sealing surfaces of the housing wall inner surfaces or axial ends.Type: GrantFiled: August 11, 2016Date of Patent: November 3, 2020Assignee: Cummins Filtration IP, Inc.Inventors: Scott W. Schwartz, Peter K. Herman, Jeremiah Cupery, Mark A. Terres

Patent number: 10544759Abstract: Air induction systems are for an internal combustion engine. The air induction systems comprise an air intake plenum that conducts intake airflow to an air cleaner for cleaning prior to combustion in the internal combustion engine. The air intake plenum is movable with respect to the air cleaner between an open position separated from the air cleaner and a closed position connected to the air cleaner. A bellows connects the air intake plenum to the air cleaner when the air intake plenum is in the closed position. The bellows has an upstream first end that seals with the air intake plenum and a downstream second end that seals with the air cleaner. A spring is disposed in the bellows. The spring applies a biasing pressure on the bellows that encourages sealing between the bellows and at least one of the air intake plenum and the air cleaner when the air intake plenum is in the closed position.Type: GrantFiled: October 24, 2017Date of Patent: January 28, 2020Assignee: Cummins Filtration IP, Inc.Inventors: Mark V. Holzmann, Kenneth M. Tofsland, Mark A. Terres

Patent number: 10486096Abstract: An axial flow air filter system is described. The system includes an axial flow filter element having a filter media. The filter media includes an inlet face and an outlet face, the inlet face spaced apart from the outlet face. The axial flow filter element includes an upper support ring adjacent to the inlet face of the filter media. The upper support ring circumscribes the filter media and supports an upper seal. The upper seal forms a seal with a housing when the filter element is received in the housing. The axial flow filter element further includes a lower support ring adjacent to the outlet face of the filter media. The lower support ring circumscribes the filter media. In some arrangements, the lower support ring does not include a seal.Type: GrantFiled: September 8, 2015Date of Patent: November 26, 2019Assignee: Cummins Filtration IP, Inc.Inventors: Scott W.

Publication number: 20170197165Abstract: A filter element including a first filter media pack with an inlet face and an outlet face and a second filter media pack with an inlet face and an outlet face. The second filter media pack is formed separately from the first filter media pack and is coupled to the first filter media pack such that the respective inlet faces and outlet faces of the first and second media packs do not overlap. The first filter media pack and the second filter media pack each include a corresponding filter media pack characteristic, and the filter media pack characteristic of the first filter media pack is different from the corresponding filter media pack characteristic of the second filter media pack. Exemplary filter media pack characteristics include the length, width, height, shape, media density, layer spacing, pleat bend angle, pleat density, and material composition of the first and second filter media packs.Type: ApplicationFiled: July 21, 2015Publication date: July 13, 2017Applicant: CUMMINS FILTRATION IP, INC.Inventors: Scott W.
