Connection arrangement for two pipes carrying hot fluids, for example internal combustion engine exhaust gases

A connection arrangement to connect two pipes (3, 4;

• 24, 25), particularly for conveying hot fluids, especially exhaust gases from an internal combustion engine.
• in which one of the pipes has an end portion facing the end portion of the other pipe, said connection arrangement permitting relative movement of the two pipes with respect to each other in axial, lateral and angular direction, while maintaining a sealed connection preventing escape of fluid to ambient space,
• comprising
• means for defining a ring chamber or space (5, 26) surrounding the end portions of the pipes (3, 4;
• 24, 25);
• at least one sealing pillow (6, 7;
• 16, 17;
• 27, 28) located in said ring chamber or space,
• the material of said sealing pillow having damped springy characteristics,
• said at least one resilient springy sealing pillow being retained in said chamber or space in a predetermined axial and radial position;
• the facing ends of the pipes being radially supported and located in position in at least approximate alignment with respect to each other by said at least one resilient or springy sealing pillow retained in said ring chamber (5, 26), and
• a sealing foil (14, 15;
• 19, 20) embedded within the material of the pillow and extending over the entire radial region of said space or chamber (5).
