摘要： A muffler assembly includes an inner outlet tube having a tubular portion, a frusto-conical portion and a flange portion having an expanded orifice facing the outlet of an inlet tube. Both the outlet tube and inlet tube extend within a chamber defined in an outer housing. The chamber is divided into two or more subchambers by a baffle which extends between the outlet tube and the housing. One or more holes in the baffle improve the sound attenuation characteristics of the muffler. The invention also comprehends a novel blank used in forming the outlet tube, and three alternative methods which may be used to form the outlet tube.

摘要： A method and apparatus for joining two tubular members in a strong, leak-proof fashion in which a band of ductile metal is passed around the adjacent ends of the members and circumferentially stressed beyond its elastic limit to conform intimately with the outer surfaces of the members throughout practically their entire circumstances. Several constructions for applying the circumferential forces are disclosed, and use is taught of a packing element to prevent paraxial or helical leakage.
