Abstract
A sound suppressor suppresses sound and flash by creating interacting paths of gas. While a first portion of the gas follows a first path through the suppressor, a second portion of the gas is diverted radially from the first path to a second path and then repeatedly made to cross the first path by a series of baffles with alternating radial passages so that the two portions of gas interfere and interact with each other, and therefore quickly give up much of their kinetic energy before they exit the suppressor. Preferably, the baffles defining the second path impart a swirl to the second portion of gas to cause the present suppressor to flush itself of carbon and metal particles. The interaction of the two portions also accelerates completion of combustion of the gas to thereby reduce flash.
