Publication number: 20240017196Abstract: A filter element includes a media pack and a support body. The media pack may be arranged in an enclosed shape defining a central cavity. The media pack includes a formed filter media and an abrasion resistant barrier coupled to the formed filter media. The support body is disposed within the central cavity. The abrasion resistant barrier separates the media pack from the support body. In some instances, the media pack also includes a plurality of adhesive beads disposed between the abrasion resistant barrier and the formed filter media and coupling the abrasion resistant barrier to the formed filter media.Type: ApplicationFiled: July 14, 2022Publication date: January 18, 2024Applicant: Cummins Filtration Inc.Inventors: Yashpal Subedi, Alexis Orea Amador, Steve Mitchell Hiles, Steve Anderson, Mark P. Adams, Jeremiah Cupery, Jason A. Scherck

Publication number: 20220355235Abstract: A filter assembly comprises a filter element and an outlet flange. The filter element comprises a filter media pack comprising a plurality of filter media layers stacked on top of each other to form the filter media pack. The filter media pack has an inlet surface being at an inlet portion of the filter media pack, and an outlet surface being at an outlet portion of the filter media pack. An outlet flange is coupled to the outlet portion of the filter media pack.Type: ApplicationFiled: August 23, 2019Publication date: November 10, 2022Applicant: CUMMINS FILTRATION IP, INC.Inventors: Kelly A. Detra, Christopher E. Holm, Mark V. Holzmann, Jerald J. Moy, Scott W. Schwartz, Ken Tofsland, Robert A. Bannister, Jeremiah Cupery, Orvin D.

Patent number: 11471805Abstract: An external brace for a filter element is described. The brace is configured to wrap around an exterior of a filter element having a filter media pack. The brace helps to support the filter media pack during filtering operations by preventing outward flexing of the filter media pack caused by fluid flowing through the filter media. In some arrangements, the brace interfaces with a filtration system housing to provide additional support to the filter element.Type: GrantFiled: March 14, 2018Date of Patent: October 18, 2022Assignee: CUMMINS FILTRATION IP, INC.Inventors: Aditya S. Murthy, Peter K. Herman, Scott W. Schwartz, Robert A. Bannister, Jason A. Scherck, Yashpal Subedi

Patent number: 11338229Abstract: Filtration systems having a normal filtration mode and an enhanced filtration mode are described. In some arrangements, the filtration system is an air filtration system having a primary air filter element, a pre-cleaner, and a pre-cleaner bypass valve. Based on feedback from an intake air quality sensor the bypass valve is either opened or closed to selectively route intake air through the pre-cleaner during sensed dirty air operating conditions (e.g., heavy dust or moisture concentrations). In other arrangements, the filtration system is a liquid filtration system (e.g., a fuel or oil filtration system) that has a main filter and a secondary filter. The filtration system selectively routes the liquid being filtered through the main filter, the secondary filter, or a combination thereof depending on a detected event or sensed characteristic of the liquid.Type: GrantFiled: February 28, 2020Date of Patent: May 24, 2022Assignee: CUMMINS FILTRATION IP, INC.Inventors: Yashpal Subedi, Dane P. Miller, Barry M. Verdegan, Shantanu Nadgir, W. Beale Delano, Andry Lesmana, Jitesh Panicker, Jeffrey L. Oakes

Patent number: 9650927Abstract: A system for providing air to an internal combustion engine is described. The system includes a crankcase ventilation unit that separates oil from the unrefined blowby gas and discharges refined blowby gas. A conduit delivers the refined blowby gas to an air cleaner housing. The air cleaner housing includes a first chamber that receives intake air through a first port, a second chamber that receives intake air from the first chamber and refined blowby gas from the conduit through a second port, and a third chamber that receives a mixture of intake air and refined blowby gas from the second chamber and discharges the mixture through a third port. A primary filter element filters the intake air as it passes from the first chamber to the second chamber. A secondary filter element filters the mixture as it passes from the second chamber to the third chamber.Type: GrantFiled: January 30, 2015Date of Patent: May 16, 2017Assignee: CUMMINS FILTRATION IP, INC.Inventors: Yashpal Subedi, Brian W.
