    摘要： A flexible line segment for the exhaust system of an internal combustion engine, with an annularly corrugated or helically corrugated metallic bellows, for exhaust gas flow therethrough, and a line segment arranged upstream in reference to the metallic bellows, with a precipitation device provided in the line section, arranged upstream in reference to the metallic bellows or mounted thereat. The precipitation device is provided for urea derivatives or urea entrained in an edge layer of the exhaust gas flow from an oversaturated edge layer of the exhaust gas flow.

    摘要： A line element for compensating for expansions and/or relative movements within a line through which fluid can flow, comprising a ring-corrugation or helical-corrugation bellows 1 and a hose 3, which is arranged coaxially in the interior of the bellows 1 and is made of a dimensionally stable material, for flow-guidance purposes. The hose 3 has a number of individual, essentially dimensionally stable ring-form hose elements 4 which are plugged axially one inside the other so as to be retained such that they can be moved axially and/or angularly in relation to one another between a compressed position and an extended position. A method for producing such a line element is also provided.

    摘要： Proposed is a line assembly (1), including: a metal hose (2) that is corrugated at least in some segments; and an inner component (3), which is arranged radially inside the metal hose at least over a partial length of the metal hose; the line assembly being distinguished by at least one coupling element (4, 4′), which coupling element is arranged between an outer border (2d) of the metal hose (2) and an outside surface (3a) of the inner component (3) and which coupling element is designed to damp the metal hose (2) by means of mechanical coupling to the inner component (3).
