  • Patent number: 7063134
    Abstract: A combined muffler and heat exchanger apparatus is provided. The apparatus includes a housing defining a heat transfer chamber and an acoustic attenuation chamber separated by a partition. A flow regulator and a fluid transport member are disposed within the heat transfer chamber. The flow regulator is adapted to regulate the flow of a first fluid, such as a heat source, between an input end of the housing and the partition. The fluid transport member is adapted to contain the flow of a second fluid. An acoustic regulator is disposed in the acoustic attenuation chamber and extends longitudinally from the partition to an output end of the housing. The acoustic regulator is a metal tube including a plurality of apertures adapted to attenuate exhaust stream acoustics associated with an automotive vehicle power source.

  • Patent number: 5836065
    Abstract: Hydroforming double wall tubular stock into an air gap tubular element comprising providing a plural wall tubular workpiece having at least an inner wall liner and an outer wall jacket having adjacent open axial ends, causing at least one of the jacket ends to extend axially beyond the adjacent liner end and to be flared outwardly, placing the workpiece into a first mold cavity of a size and configuration to result in the desired size and configuration of the liner, sealing the open ends of said liner, injecting hydroforming fluid into said liner to fill it and applying pressure thereto to expand the liner and jacket in the first mold cavity, releasing the pressure, placing the workpiece in a second mold cavity of a size and configuration desired for the jacket on a resulting air gap tubular element, providing hydroforming end closures to seal off the jacket ends, at least one of the end closures having an annular shoulder aligned with the flared extended jacket end radially outwardly offset from the adjacent
