Abstract
A noise suppressor device for absorbing pulsating fluids is disclosed. A noise suppressor device has a housing which defines an axially extending bore. A resilient bladder is coaxially positioned in the bore. A spool assembly is coaxially positioned within the bladder. The spool assembly has an inner spool layer and an outer spool layer which coaxially surrounds the inner spool layer. The inner spool layer and outer spool layers each define a plurality of perforations extending therethrough. The perforations in the outer spool layer are offset from the perforations in the inner spool layer such that a direct line of sight through the first perforations and second perforations is prevented.
