Title: Damping double metal tube
Inventor: MATSUMOTO TAKESHI
IPC: F16L9/04
Filed: 1988-12-29
Abstract: PURPOSE:To dampen vibration by providing a very minute gap having a specific size in an outer tube and inserting an inner tube therein in an exhaust pipe etc for automobiles. CONSTITUTION:In case of a double tube, gaps having very minute specific areas wherein an inner tube and an outer tube can be touched each other due to vibration are provided between both the tubes to obtain damping effect and the damping effect can be improved thereby. Namely, the gap in 10-150mum are provided between the inner surface of the outer tube and the outer surface of the inner tube, and the inner tube is inserted in the outer tube to form damping double metal tube. The reasons of the limitation of the gap are as follows; in case the size of the gap is smaller than 10mum contact portions between the inner/outer tubes increase to form nearly the condition of a single tube because the tube has unavoidable sinuosity, in case of over 150mum, during vibration, the outer wall of the inner tube and the inner wall of the outer tube are striked each other to generate so called 'trembling sound' and also no sufficient damping can be obtained due to a little contact of the wall faces of the tubes.
