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. Each spring means consists of at least a single leaf-type spring element which a) extends in a substantially radial plane of the decoupling device, b) is supported at the end portions thereof with axial clearance at portions of said housing circumferentially spaced from each other, c) is prevented from moving in a circumferential direction with respect to a longitudinal centerline, and d) engages at an intermediate portion thereof a recess formed in said conduit connecting member and oriented to said spring element. The spring means during movement of said conduit connecting member relative to said housing engages portions of said conduit connecting member defining the recess for transmitting a force therebetween.
