Elastic pipe connection for vehicle exhausts - uses corrugated ring membrane fastened along two edges with facing overlapping flanges to maintain spacing

摘要

The elastic connection is for the ends of two pipes, which concentrically surround each other, and form an intermediate space, for vehicle exhausts. The space contains a corrugated section supporting the pipe ends. The section is formed from a ring membrane (6, 7) with a circumferential corrugation. The internal and external edge (8, 9) of the membrane each engage axially on one of the pipes (2, 4). One of the edges is clamped into a circumferential groove (10, 11) in a ring section (12, 13) fastened to the other pipe. Both ring sections have facing overlapping flanges (18, 19), with the flanges of one section projecting into the axial distance between those of the other, maintaining the defined axial distance (a).
