Intermediate conduit between two pivotally connected conduits

摘要

An intermediate conduit extends between and interconnects adjacent pivotally connected ends of a pair of conduits. The intermediate conduit is disposed in at least one turn about the pivotal interconnection, and the distance between the ends of the intermediate conduit is substantially greater than its length. A damping device such as a dashpot interconnects the intermediate conduit and one of the pair of conduits and acts in a direction parallel to the axis of the turns of the intermediate conduit.
