Patent attributes
A device for attenuating energy along a conduit, comprising a first member having an essentially semi-cylindrical outer surface and a first cavity extending substantially longitudinally from end to end. A second member having an essentially semi-cylindrical outer surface is provided, with the outer radii of the first and second members being the same. The second member also has a longitudinally extending cavity. When the two members are secured to one another to form the device, the two cavities face one another to form a bore that extends from end to end and has respective opposed tapered portions having a circular cross-sectional configuration that decreases in diameter inwardly. The bore also has a central, cylindrical portion disposed between the tapered portions and having an axial length that is no greater than one third of the overall axial length of the device.
