<p>A silencer for attenuating sound coming from a source,having high and low fluid pressure and flow variations is disclosed. The silencer features a housing having an inlet connected to the source, a throat and two divergent branches for the flow of fluid therethrough. A first means coupled to the throat directs fluid pressure and flows from the source to one of the branches and a second means coupled to the throat diametrically opposed to the first means diverts the fluid pressure and flow to the other branch when the pressure in the second means is greater than the fluid pressure and flow at the first means. The second means includes a means for deriving a mean pressure, viz., attenuates peak pressures so that fluid pressure and flow variations at the other one of the divergent branches are reduced.</p> |
