ABSTRACT:
The present invention discloses a sound muffling system which utilizes natural forces such as destructive resonance, coriolis effect, and ramcharging effect to provide a highly efficient low back-pressure muffler for internal combustion engines, compressors, and other machines emitting a pulsed gaseous stream. The system utilizes inlet and outlet coaxial flow tubes with radial ports and a stator/baffle located concentrically in an outer shell.
