  • Valve and filter assembly for a regeneration system
    Patent number: 9291126
    Abstract: A regeneration system includes a housing defining an exhaust flow path. An inlet of the housing is configured to receive an exhaust flow from the internal combustion engine and an outlet of the housing is configured to direct the exhaust flow toward an exhaust aftertreatment component. A combustion head is coupled with the housing and configured to direct air and fuel to a combustion chamber in fluid communication with the exhaust flow path. A fuel supply passage is defined by the combustion head and is in fluid communication with the combustion chamber. The regeneration system also includes a valve and filter assembly disposed within the fuel supply passage. The valve and filter assembly includes an assembly housing defining a reduced fuel supply passage, a filter material coupled with the assembly housing, and a check valve at least partially disposed within the reduced fuel supply passage.
