Exhaust bellows for dynamic torsion control in an exhaust system

摘要

A flexible bellows tube connecting pipes (2) in a system such as a vehicle exhaust system (4). Various embodiments are disclosed, with each including two conduit sections having mating corrugations that overlap to provide a seal while allowing the two sections to rotate in response to torsion loading. Different configurations of the interfitting corrugations and related structure are disclosed in the different embodiments. <IMAGE>
