Patent number: 10029197Abstract: A fluid filter assembly of a filtration system is described. The filter assembly described includes a cover member and a filter cartridge having at least one filter element and a plate member. The plate member includes a seal surface on one side facing the cover member, and a seal surface on another side facing away from the cover member. The seal surface facing the cover member is configured to seal with the cover member, and the seal surface facing away from the cover member configured to seal with another component of the filtration system. The assembly provides a structure that can retain a seal between sealing surfaces of the cover and the filter cartridge, at least while the fluid filter assembly is being serviced, so as to at least minimize fluid dripping and leakage.Type: GrantFiled: February 5, 2018Date of Patent: July 24, 2018Assignee: CUMMINS FILTRATION IP, INC.Inventors: Mark V.

Patent number: 8974567Abstract: A gas-liquid rotating coalescer includes first and second sets of one or more detent surfaces on a rotary drive member and a driven annular rotating coalescing filter element which engagingly interact in interlocking mating keyed relation to effect rotation of the coalescing filter element by the rotary drive member. Designated operation of the coalescer requires that the coalescing filter element include the second set of detent surfaces. A coalescing filter element missing the second set of detent surfaces will not effect the noted designated operation.Type: GrantFiled: June 24, 2011Date of Patent: March 10, 2015Assignee: Cummins Filtration IP Inc.Inventors: Barry M. Verdegan, Howard E. Tews, Roger L. Zoch, Bradley A. Smith, Kwok-Lam Ng, Benoit Le Roux, Chirag D. Parikh

Publication number: 20140033922Abstract: A two stage gas-liquid separator assembly includes a housing having an inlet for receiving a gas-liquid stream and an outlet for discharging a gas stream. A first plenum chamber includes a pre-separator that causes liquid to separate from the gas-liquid stream and to drain to a lower portion of the first plenum chamber. A second plenum chamber includes a main separator downstream of the pre-separator that further causes liquid to separate from the gas-liquid stream and to drain to a lower portion of the second plenum chamber. A first drain port drains liquid from the lower portion of the first plenum chamber and a second drain port drains liquid from the lower portion of the second plenum chamber. Liquid drains from the first and second plenum chambers regardless of a pressure difference between a pressure in the first plenum chamber and a pressure in the second plenum chamber.Type: ApplicationFiled: July 30, 2013Publication date: February 6, 2014Applicant: Cummins Filtration IP, Inc.Inventors: Lee A.
