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: 11446595Abstract: A fuel filter system that does not require the periodic draining of a water sump. The system includes a fuel tank for storing fuel and a fuel filter fluidly coupled to the fuel tank for separating water from the fuel. A fuel pump has a suction side and a high pressure side. The high pressure side of the fuel pump is fluidly coupled to the fuel filter for pumping fuel to the fuel filter. A water emulsifier, such as an orifice, is fluidly coupled to the fuel filter to receive water and fuel from the fuel filter and form a water-fuel emulsion. The water-fuel emulsion is supplied to any point in the system on the suction side of the fuel pump, such that the water-fuel emulsion passes through the fuel pump and fuel filter.Type: GrantFiled: October 21, 2016Date of Patent: September 20, 2022Assignee: CUMMINS FILTRATION IP, INC.Inventors: Gérard Malgorn, Pierrick Bonzi, Travis E.

Patent number: 11198077Abstract: A “no filter, no run” filtration system that is designed to verify that a filter cartridge is present to safe-guard against damage to fuel injectors, associated fuel components, etc. and engine malfunctions. Fuel flow to the engine is prevented altogether or permitted in an amount insufficient to allow engine operation if a filter cartridge is not installed, and an appropriately designed filter cartridge is required to be used in order to permit sufficient fuel flow for engine operation. In one embodiment, a flow restriction valve is provided that includes a ball.Type: GrantFiled: January 4, 2018Date of Patent: December 14, 2021Assignee: CUMMINS FILTRATION IP, INC.Inventors: Zemin Jiang, Wassem Abdalla, Jeffrey B.
