Abstract: A flexible connection arrangement for connecting a pipe of an exhaust system to an engine is provided at one of its axial ends with a fastening flange and at its other axial end with a connection piece for the end of the pipe to be received. The connection piece and fastening flange are connected with one another via a helical spring. A metallic bellows and a damping insert which extends coaxially to the bellows, encloses the bellows radially externally and contacts the turns of the bellows are provided between the connection piece and the fastening flange. The helical spring is connected at both of its axial end regions with the connection piece and fastening flange, respectively. The connection at the fastening flange is effected via two fastening locations, one of which lies at that end of the helical spring, while the second fastening location is arranged so as to be offset to the first fastening location by an angle of 45.degree. to 53.degree..

Abstract: A conduit vibration decoupling device, particularly for exhaust systems of internal combustion engines, comprises a pair of axially spaced conduit connecting members connected with each other by a flexible, bellows-type connecting element, and a force transmitting means having at least axial elasticity for transferring forces between said conduit connecting members. The force transmitting means comprises a housing surrounding said. flexible connecting element and connected to at least one of the conduit connecting members by an articulated spring arrangement which comprises at least a pair of spring means circumferentially spaced from each other.

Abstract: In a flexible connection arrangement for two pipe portions having a metallic bellows which is connected axially on either side in a gastight manner with connection pieces, the sides of the connection pieces facing the bellows are provided with radially widened end portions. Also provided are a damping insert, which extends coaxially relative to the bellows a along its length and is in a working connection therewith, and heat protection device for the bellows acting in the radially inward direction. The damping insert encloses the bellows radially outwardly such that the turns of the bellows contact the damping insert. The lateral end regions of the damping insert are held in the widened end portions without being fastened thereto and are supported radially outwardly by the latter. The connection pieces are connected with one another via a spring which surrounds the damping insert radially outwardly.
