Patent number: 11434857Abstract: Various example embodiments relate to an automatic drain system for use with a fluid water separator. The automatic drain system includes a liquid-in-fuel sensor. The liquid in-fuel sensor is configured to detect a liquid level in a water sump. The solenoid has an open state and a closed state. A control unit is configured to activate the solenoid in response to a signal from the liquid-in-fuel sensor. Activation of the solenoid causes the solenoid to go from the closed state to the open state. The automatic drain system is placed in a condition for allowing fluid flow through the automatic drain system from the water sump.Type: GrantFiled: October 11, 2018Date of Patent: September 6, 2022Assignee: CUMMINS FILTRATION IP, INC.Inventors: Brian K. Wagner, Bryan P. Steffen, Ayesha Saha, Erica C. Clark-Heinrich, Anil I. Sawant, Sonal Laxman Chirme, Mahesh Suresh Chindarkar, Barry Mark Verdegan

Patent number: 11358089Abstract: A filter that is retained in a shell housing by the use of a snap connection. The filter includes an endplate having snap features that interact with a groove in an inner portion of the shell housing. The groove may extend 360 degrees around an inner circumference of the shell housing. Accordingly, when the shell is unthreaded from the head service (e.g., during a filter replacement service), the shell only needs to be displaced the length of the inner radial seal interface between the shell and the head, not the entire length of the filter media thereby minimizing the stroke length needed to service the filter assembly.Type: GrantFiled: July 12, 2018Date of Patent: June 14, 2022Assignee: CUMMINS FILTRATION IP, INC.Inventors: Bradley A. Smith, Chirag D. Parikh, Brian K. Wagner, Scott Manke

Patent number: 10737210Abstract: A filter precleaner for precleaning an unfiltered gaseous mixture. A coalescing filter includes a filter media for filtering a gas, a nozzle assembly for precleaning an unfiltered gaseous mixture, and a lower endplate. The nozzle assembly includes a first nozzle plate positioned upstream of the filter media. The lower endplate is positioned at a lower end of the filter media beneath the first nozzle plate. The lower endplate allows liquid to drain through the lower endplate. The unfiltered gaseous mixture impacts the lower endplate such that liquid from the unfiltered gaseous mixture flows through the lower endplate and gas from the unfiltered gaseous mixture flows through the filter media.Type: GrantFiled: August 23, 2016Date of Patent: August 11, 2020Assignee: CUMMINS FILTRATION IP, INCInventors: Brian K.

Patent number: 10473059Abstract: A natural gas fueling system supplies methane gas to an engine and includes a filter assembly. The filter assembly includes a gas inlet configured to receive inlet gas and a methane permeable filter configured to separate methane gas and first contaminant gases from the inlet gas. The natural gas fueling system also includes a reformer apparatus configured to convert the first contaminant gases into a reformed gas stream including methane gas. The reformed gas is supplied to the gas inlet and is recirculated through the filter assembly to extract the methane gas from the reformed gas stream.Type: GrantFiled: February 9, 2018Date of Patent: November 12, 2019Assignee: Cummins Inc.Inventors: Corey W.

The filter includes an endplate having snap features that interact with a groove in an inner portion of the shell housing. The groove may extend 360 degrees around an inner circumference of the shell housing.

Patent number: 5779900Abstract: A filter (102) for filtering fluid from a machine (104) includes a filter housing (106, 250) having a first inlet (114) receiving a first fluid from the machine, a first outlet (116) returning the first fluid to the machine, a second inlet (118) selectively receiving a second fluid from a source (120) of cleaning fluid, and a second outlet (122) for exhausting the second fluid and for exhausting the first fluid from the dirty side of the main filter element (124) in the housing backwashed by the second fluid. The filter housing has a first flow path (126) therethrough from the first inlet then through the filter element in one direction then to the first outlet, and has a second flow path from the second inlet then through the filter element in the opposite direction then to the second outlet, the first and second flow paths having common but opposite direction portions through the filter element. A second filter element (156) is provided in the second flow path.Type: GrantFiled: November 22, 1996Date of Patent: July 14, 1998Assignee: Nelson Industries, Inc.Inventors: Christopher E.
