  • Exhaust treatment device having flow-promoting end caps
    Patent number: 8359848
    Abstract: An end cap for an exhaust treatment device is disclosed. The end cap has a cylindrical housing with an axial direction, a radial direction substantially orthogonal to the axial direction, a first open end, and a second closed end opposing the first open end in the axial direction. The end cap also has an integral port member extending from an annular surface of the cylindrical housing. The integral port member has a central axis aligned in the radial direction, and an exterior surface of the integral port member tangentially connects to an exterior surface of the cylindrical housing.
    Type: Grant

  • Connecting duct for fluid compression system
    Patent number: 7032383
    Abstract: A connecting duct for providing a fluid pathway between an outlet of a low pressure compressor and an inlet of a high pressure compressor is provided. The connecting duct includes a main body that defines a fluid pathway adapted to direct a flow of fluid between a main body inlet and a main body outlet. The main body also includes a diffusing section that decreases a velocity of the flow of fluid. A flow de-swirling section is disposed between the diffusing section and the outlet of the main body. The flow de-swirling section straightens the flow of fluid.
