Patent number: 11951431Abstract: Rotating coalescer elements that maximize the radial-projected separation surface area in a given (rotating) cylindrical volume, where flow to be cleaned is passing axially upward or downward through a separating media of the rotating coalescer element. Various example package assemblies are provided with various types of rotating configurations including cylindrical coiled media packs, frustum coiled media packs, concentric cylinders, coiled metal or polymer films with and without perforations, and/or alternating layers of different materials. The described rotating coalescers may be driven by hydraulic turbine, electric motor, belt, gear or by mounting on rotating machine components, such as rotating engine shafts or connected components.Type: GrantFiled: August 15, 2022Date of Patent: April 9, 2024Assignee: CUMMINS FILTRATION IP, INC.Inventors: Christopher E. Holm, Peter K. Herman, Arun P. Janakiraman, Gerard Malgorn, Chirag D. Parikh, Anthony Barreteau, Ronan Corvec, Ken Tofsland

Patent number: 11865488Abstract: Filter media having a design embossed into the media are described. In some arrangements, the filter media is pleated filter media. In other arrangements, the filter media includes a plurality of channels, such as tetrahedron channels. The filter media includes a pattern of interrupted straight or angled embossments that help maintain separation between adjacent layers of the filter media. The embossments allow for two adjacent media layers (e.g., mating surfaces of the filter media) to remain separated, thereby increasing dust holding capacity and lowering pressure drop ever similarly configured filter media not having the embossments.Type: GrantFiled: July 11, 2022Date of Patent: January 9, 2024Assignee: Cummins Filtration IP, Inc.Inventors: Emmanuel Page, Anthony Barreteau, Kurt M. A. Badeau, Christopher E. Holm

Patent number: 11654385Abstract: Referring to the figures generally, a rotating filter cartridge includes a first endcap, a second endcap, and a filter media. The filter media is positioned between the first endcap and the second endcap. The filter media creates a mechanical seal between at least one of the first endcap or the second endcap during rotation of the rotating filter cartridge without the use of a potting material. In at least one embodiment, the rotating filter cartridge further includes a body secured to the first endcap and the second endcap. At least one of the first endcap or the second endcap, and the body, may form a pocket that radially pinches the filter media to form the mechanical seal.Type: GrantFiled: September 20, 2016Date of Patent: May 23, 2023Assignee: CUMMINS FILTRATION IP, INCInventors: Himani Deshpande, Christopher E. Holm, Anthony Barreteau, Chirag D Parikh, Gérard Malgorn, Alain Olier, Bradley A Smith, Benjamin L Scheckel, Lee A. Peck, Brian W. Schwandt, Ken Tofsland

Patent number: 11619152Abstract: A crankcase ventilation system comprises a housing defining an internal volume structured to receive a. rotating air/oil separator element. The housing has a housing inlet structured to receive a fluid and a housing outlet defined tangentially in a sidewall of the housing which is structured to allow the fluid to exit the housing. An outlet conduit is fluidly coupled to housing outlet. The outlet conduit comprises an outlet conduit first portion axially aligned with the housing outlet, and an outlet conduit second portion positioned downstream of the outlet, conduit first, portion. A swirl breaking structure is positioned in at least one of an outlet conduit inlet and the outlet conduit second portion. The swirl breaking structure is configured to disrupt swirling flow of the fluid into the outlet conduit so as to reduce a pressure drop experienced by the fluid as the fluid flows from the housing into the outlet conduit.Type: GrantFiled: November 9, 2018Date of Patent: April 4, 2023Assignee: CUMMINS FILTRATION IP, INC.Inventors: Navin Surana, Vijay Dinkar Kolhe, Anthony Barreteau, Peter K.

Patent number: 11448107Abstract: Various example embodiments relate to rotating coalescers. One embodiment includes a housing comprising a first housing section having a blowby gas inlet structured to receive crankcase blowby gases from a crankcase. The housing further comprises an oil outlet. The rotating coalescer includes an endcap and filter media. The filter media is arranged in a cylindrical shape and is coupled to and positioned between the first housing section and endcap. The filter media is structured to filter the crankcase blowby gases passing through the filter media by coalescing and separating oils and aerosols contained in the crankcase blowby gases. The rotating coalescer includes a hollow shaft extending through the housing and positioned radially inside of the filter media. The hollow shaft forms a blowby gas outlet structured to route filtered crankcase blowby gases out of the housing. The rotating coalescer further includes a drive mechanism operatively coupled to the hollow shaft.Type: GrantFiled: August 23, 2021Date of Patent: September 20, 2022Assignee: Cummins Filtration IP, Inc.Inventors: Anthony Barreteau, Christopher E.

Patent number: 10596507Abstract: Assembly to be used to filter a fluid, containing a housing (29) which comprises a housing base (50) and a housing upper part (30) connected removably to the housing base (50). An axial shaft (34, 35) extends at least partially through the filter element (32, 33) when the filter element (32, 33) is contained inside the housing (29). A lower bearing (44) is arranged between the axial shaft (34, 35) and the housing base (50) and underneath the filter element (32, 33) when a filter element (32, 33) is contained inside the housing (29). The housing (29) is able to contain a filter element (32, 33) within it and the filter element (32, 33) fits onto the axial shaft (34, 35) in such a way that the axial shaft (34, 35) is rotationally coupled to the filter element (32, 33). The filter assembly (20, 120) has no bearing above the filter element (32, 33).Type: GrantFiled: June 15, 2016Date of Patent: March 24, 2020Assignee: CUMMINS FILTRATION SARLInventors: Anthony Barreteau, Kevin Maguer, Chirag D.
