Abstract
An exhaust-vibration decoupling connector has an inlet tube (1) extended downstream from a decoupler inlet (2) to an inlet-tube step (22). The inlet-tube step includes a radially inward extension of the inlet tube to a damper seat (23) that includes further downstream extension of the inlet tube. An outlet tube (4) is extended upstream from a decoupler outlet (5) to an outlet-tube step (24) that includes a radially inward extension of the outlet tube to proximate an outside surface of the damper seat. A vibration damper is positioned removably in a damper fixture (3) that includes the damper seat intermediate the inlet-tube step and the outlet-tube step proximate midway between the decoupler inlet and the decoupler outlet. Surrounding the vibration damper, a decoupler bellows (7) has an upstream bellows attachment (9) proximate an outside periphery of the inlet tube and a downstream bellows attachment (10) proximate an outside periphery of the outlet tube. Enclosing an outside periphery of the decoupler bellows is a flex cover (13) that is extended from proximate the decoupler inlet to the decoupler outlet. The decoupler inlet is articulated for attachment to an exhaust-outlet stru…
