Gas-tight decoupling unit for e.g. passenger car`s exhaust system, has hoses and edge units to form annular cavity between hoses with suitable pneumatic connection, which is pressurized in operating condition using ambient air

The unit has a pair of coaxially arranged multi-layer strip wound metal hoses (11, 13) and axial edge units (14, 15) to form an annular cavity (12) between the two stripwound hoses with a suitable pneumatic connection, which is pressurized in an operating condition using ambient air. The pressure is...

More Information
Summary:The unit has a pair of coaxially arranged multi-layer strip wound metal hoses (11, 13) and axial edge units (14, 15) to form an annular cavity (12) between the two stripwound hoses with a suitable pneumatic connection, which is pressurized in an operating condition using ambient air. The pressure is higher than dynamic pressure, which is built up in an inside cylindrical exhaust system cavity as a result of exhaust gas flow.
