Flexible Verbindungsanordnung für zwei Rohrteile, insbesondere bei Abgasanlagen von Kraftfahrzeugen

摘要

In a flexible connection for two pipe sections with a metal bellows (3) gastightly connected axially on both sides to connectors (1; 2), the sides of the connectors (1, 2) towards the bellows (3) have radially widened end sections (4, 5) with cylindrical end regions (10, 11). There are also a damping insert (12) coaxial with the bellows, extending over its length and integral therewith and an internally effective heat protector (16) for the bellows (3). The damping insert (12) surrounds the bellows (3) on the outside and the bellows' corrugations (3') lie against it. The lateral end regions of the damping insert (12) are held in the end sections (4, 5) without a clamp and are supported radially outward thereby. The connectors (1, 2) are secured together via a spring (13) radially surrounding the damping insert on the outside. The heat protector takes the form of a pipe section (16) running coaxially with the bellows (3) with a radial distance inside it and is secured to the forward connector (1) in the direction of flow.
