Exhaust system with conduit element

摘要

The flexible duct element (14) has an annular or helical shaped metal bellows (15) in which the exhaust gas stream (8) flows. A conical flow guide (16) is tapered in the direction of flow of exhaust gas stream and protruded into an inlet area (17) of the metal bellows in a detached manner, to flow the exhaust gas stream. The solid structure of conical flow guide is formed of ceramic foam portion, wire netting, or wire mesh. An independent claim is included for an exhaust system for flexible duct element.
