Patent number: 10786769Abstract: 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: December 3, 2010Date of Patent: September 29, 2020Assignee: CUMMINS FILTRATION IP, INC.Inventors: Zemin Jiang, Wassem Abdalla, Jeffrey B. Sharp, Hendrik Amirkhanian, Jeff Husband, Abby True-Dahl

Patent number: 10774798Abstract: A fuel water separator filter that is configured as a filter-in-filter construction with multiple water separating layers to separate water from the fuel. The fuel water separator filter is configured for use on a suction side of a fuel pump, and includes a neck with a radially outward facing seal that in use seals with the filter housing. The filter housing is formed with an isolated water sump that in use is isolated from water that is stripped from the fuel by the first stage of the outer filter.Type: GrantFiled: March 1, 2016Date of Patent: September 15, 2020Assignee: CUMMINS FILTRATION IP, INC.Inventors: Zemin Jiang, Amit Shashikant Wankhede, Sonali Dattatraya Bisurkar, Jayant Singh, Melvin Rice, Manikandan Annamalai

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.

Patent number: 8496816Abstract: A fuel heater module and a water-in-fuel sensor module are disclosed that are configured to be connected to an outside surface of a filter assembly. The fuel heater module includes an inlet port and an outlet port with a heating element positioned in the fluid path between the inlet and outlet. A thermostat is included for controlling operation of the heating element. The water-in-fuel sensor module is configured to detect water in the filter housing that it may be drained from the filter housing. Both modules are configured to be attached to an outside surface of the filter housing thereby being readily replaceable.Type: GrantFiled: September 24, 2008Date of Patent: July 30, 2013Assignee: Cummins Filtration IP, Inc.Inventors: Abby True-Dahl, Gerard Malgorn, Arnuad LeVen, Gildas LeMen, Mark Wieczorek, Zemin Jiang, Jeffrey A.
