Flexible duct element for exhaust system of e.g. diesel engine of motor car, has coaxial flow-guiding hose arranged in inner side of metal hose, where flow-guiding hose is extended over upstream portion of element

摘要

The element has a metal hose (3) coaxially arranged within a ring-curved or screw thread-shaped curved metal bellow (1). A coaxial flow-guiding hose (10) i.e. braided fabric hose, is arranged in an inner side of the metal hose, where the flow-guiding hose is extended over an upstream portion of the element. The flow-guiding hose is connected with the metal hose in a region of an upstream end of a duct part. The flow-guiding hose and metal hose are interconnected by a connector (6). A transition portion of the connector is provided with circumferentially distributed through-flow apertures. The coaxial flow-guiding hose is made of textile material and metal wires and/or ceramic fibers. An independent claim is also included for a connector.
