Publication number: 20230338879Abstract: A spin-on filter comprises a housing shell, a filter element, a nutplate, and a gasket. The filter element is positionable within the housing shell and comprises a filter media and an endplate. The nutplate is positionable within the housing shell. The gasket comprises a central body and a spring-loaded extension. The spring-loaded extension circumferentially surrounds and extends radially from the central body. The spring-loaded extension is axially flexible between an expanded position and a compressed position. The spring-loaded extension forms and maintains a first seal with the endplate and maintains contact with the nutplate as the spring-loaded extension moves between the expanded position and the compressed position.Type: ApplicationFiled: June 17, 2021Publication date: October 26, 2023Applicant: Cummins Filtration Inc.Inventors: Eric Roysdon, Jeff A. Bowerman, Adam DaGardeyn, Sonia Rajendra Kasbekar, Aaron M. Wells, Mikiya Paul

Publication number: 20230277964Abstract: A filtration system having an undulated interlocking housing-endplate interface geometry is described. In the filtration system, a filter element endplate and a filter housing component (e.g., a shell housing, a filter mounting head, etc.) meet at an interface. The filter housing component includes an undulating or repeating pattern that meshes with a matching undulating or repeating pattern on the endplate of the filter element. The undulating or repeating pattern prevents the filter element from freely rotating with respect to the filter housing component of the filtration system.Type: ApplicationFiled: May 12, 2023Publication date: September 7, 2023Applicant: CUMMINS FILTRATION IP, INC.Inventors: Philip M. Ouweleen, Zemin Jiang, Ted S. Loftis, Karthik Kothakota, Mano Raj Sekar, Mark J. Johnson, Aaron M. Wells, Robert A. Bannister, Joshua Crooks, Brian M. Palmer, Sean M. Grabein, Conner D. Oren

Patent number: 10786767Abstract: A filter apparatus is described that has a torque limiting device, which may be a clutch mechanism, and which provides a protective function for a filter, so as to protect a filter from being over tightened and to thereby prevent damage to filter components. The clutch mechanism can also eliminate or reduce the need for torque measurement of certain filter components. The clutch mechanism can be located on one of the fluid filter, a filter head which engages the fluid filter, or a combination of both the fluid filter and the filter head.Type: GrantFiled: March 11, 2016Date of Patent: September 29, 2020Assignee: CUMMINS FILTRATION IP, INC.Inventors: Kurt M. A. Badeau, Travis E. Goodlund, Bryan J. Benz, Bryan P. Steffen, Ismail C. Bagci, Aaron M. Wells, Rahul B. Kallurwar, James L. Eickhoff, Chirag D. Parikh, Gregory W. Hoverson, Kevin C. South, Scott G.

Patent number: 9308476Abstract: A fluid filter device is described, where a flow attachment member provides a unique interface between the filtering element and a filter head. The fluid filter described herein generally provides a flow structure that is localized and sealed. The flow attachment member is configured to communicate fluid into and out of the fluid filter, and is configured to localize fluid flow both into and out of the fluid filter within a separating structure of the flow attachment member. The flow attachment member further includes a seal structure configured to substantially prevent or at least confine leakage to a localized area away from proximity of the edges of the housing. A composite filter head is described that has integrally molded inlet and outlet fittings.Type: GrantFiled: April 20, 2010Date of Patent: April 12, 2016Assignee: CUMMINS FILTRATION IP, INC.Inventors: Harold R. Martin, Rahul Kallurwar, James L. Eickhoff, Ismail C. Bagci, Jeffrey A. Husband, Aaron M. Wells, Kevin C. South

Patent number: 8932465Abstract: A filter within a filter cartridge design is described that includes a sealing structure on an endplate of an outer filter element. Generally, the sealing structure includes an annular flange on the endplate that can directly seal against an interior surface of a housing when the filter cartridge is assembled for use. During filtration, the annular flange prevents a working fluid from bypassing the outer filter element. The sealing flange can seal with the housing in a press fit engagement.Type: GrantFiled: November 27, 2012Date of Patent: January 13, 2015Assignee: Cummins Filtration IP Inc.Inventors: Aaron M. Wells, Terry W. Shults, Ismail C. Bagci, Dean Olson, Zemin Jiang, Kevin C. South, Peter K. Herman, Hendrik N. Amirkhanian, Jeffrey B. Sharp, David P. Genter, Norman C.

Publication number: 20140083922Abstract: A filter assembly that includes a shell having anti-rotation features that prevent rotation of the shell relative to the nutplate and a method for producing the disclosed filter assembly are described. The anti-rotation features are knurls and/or surface disruptions that are formed on a surface of a flange on an open end of the shell. The knurls and/or surface disruptions that are formed on a surface on the flange can aid in gripping a surface of an upper groove of the nutplate.Type: ApplicationFiled: September 27, 2013Publication date: March 27, 2014Applicant: Cummins Filtration IP, Inc.Inventors: Bryan A.

Publication number: 20120248024Abstract: A filter and replacement filter cartridge is provided with a pulsation dampener mounted and sealed to the filter cartridge basket at an inner diameter thereof. The pulsation dampener is captive to the basket such that removal of the basket from the filter housing canister removes all of the basket, filter media, and pulsation dampener as a single unit without separate, loose parts thereof. An axial extension section of the basket facilitates gripping and removal, and maintains a fully seated installed filter position. Sealing is provided without a section of the pulsation dampener interposed between the filter housing canister and lid.Type: ApplicationFiled: January 12, 2012Publication date: October 4, 2012Applicant: KUSS FILTRATION, INC.Inventors: Aaron M.
