  • Patent number: 4875716
    Abstract: A jointed connection for pipes, especially motor vehicle exhaust pipes (9, 10), features a flexible surrounding conduit element (3, 103, 117) and a support member (11, 12; 105, 116, 130, 145, 146, 157) which connects the pipes through support pads (13, 14; 109; 121, 133, 143, 144, 160) in a load-bearing but angularly flexible and elastically damped manner. An inner protective tube (7, 8; 104; 114; 127, 128; 141, 142; 156) is attached to the pipe not attached to the support member, and the support pads are radially confined between the support element and the inner protective tube. The support pads are also axially engaged with the inner protective tube and the support member, or with additional elements (107, 131) attached thereto. The result is a structure which is compact, yet provides flexibility and elastic damping while protecting from corrosion the elements responsible for the flexibility and elasticity.
