A variable resonator silencer for subsequent scaffolding on ship exhaust gas pipes

摘要

The present invention describes a lambda - quarter - resonator silencer for use on exhaust gas pipes of constantly running ships machinery which, even after the start of operation of the ship, and also above the chimney cover can be installed. The muffler has a, in their position variable, end disk, as a result of which the natural frequency of the resonator to the frequency can be adapted to be damped. Thus, it is also possible in a variation of the speed of sound in the exhaust gas and an associated displacement of the frequency to be damped, the effectiveness be guaranteed.
