US Patent 9500108 Split path silencer

A silencer having an outer shell with a first opening at a first end is configured with two flow paths and designed to attenuate sound waves. A tube is positioned within the outer shell, the tube having a first end and a second end forming a path through the interior of the silencer. A baffle is positioned between the inner tube and the outer shell to form a second path through the silencer. The first path may be longer than the second path. The sum of the cross-sectional areas of the first path and second path may be equal to the cross-sectional area of the first opening.
