Abstract:
A vibration decoupler apparatus, for connecting first and second components of a fluid conduit system, comprising:a mounting member, having an aperture therethrough for the passage of fluid, the aperture having an inside surface, the mounting member being configured for attachment to one of the first and second components; a pipe member, having at least a first end region and a second end region; a resilient flexible sealing member, substantially surrounding at least a portion of the pipe member, and having two ends, a first of the two ends being operably connected to the first end region of the pipe member, a second of the two ends being operably connected to the mounting member, at least a portion of the second of the two ends of the resilient flexible sealing member extending through the aperture in the mounting member, and having a convolution formed therein, having a diameter greater than that of the aperture in the mounting member, to provide a radially inwardly turned lip, for forming, in part, upon completed attachment of the mounting member to one of the first and second components, a substantially fluid-tight weldless seal between the mounting member and said one of the first and second components; a deformable annular vibration damping member, radially captured between a portion of the second end of the resilient flexible sealing member and, in turn, at least a portion of an inner surface of the aperture in the mounting member, and a portion of the second end region of the pipe member, the second end region of the pipe member being disposed in vibration absorbing contact with the vibration damping member, for enabling restricted relative axial, lateral and angular movement between the pipe member and the mounting member, when the mounting member is affixed to a structural member in a fluid transport system; and the radially inwardly turned lip extending radially inward to a position substantially proximate a peripheral region of the second end of the pipe member, for substantially deflecting exhaust gases away from the annular vibration damping member.
