Silencer on the intake side of a compressor with assembly of axially spaced annular sound-damping elements

In a silencer construction for connection to the intake side of a compressor which comprises an assembly of axially spaced annular sound damping elements forming air flow passages therebetween, said damping elements being located in a housing part of the silencer which is connected to a convergent intake manifold serving as the main flow path for the ingested air which flows inward through the spaces between the damping elements, the improvement wherein an inner circumference of each of said damping elements merges into an air guiding element having a curvilinear configuration which functions to deflect the partial air flows leaving said air passages between said damping elements in the direction of the main air flow established by said convergent manifold, and wherein the sum of the leaving cross-sections of all of said partial air flow passages is approximately equal to the average flow cross-section of said manifold.
