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.

[ We claim:] [1.] A noise suppressor device comprising:a housing defining an axially extending bore through which pressurized fluid flows;a bladder coaxially positioned in the bore;a spool assembly coaxially positioned in the bladder, the spool assembly consisting of an inner spool layer and an outer spool layer which axially surrounds the inner spool layer, the inner spool layer having radially oriented first perforations extending therethrough, the first perforations being in communication with axially oriented fluid flow paths circumferentially extending around an outer surface of the inner spool layer, the outer spool layer having radially oriented second perforations extending therethrough; andthe first perforations extending through the inner spool layer defining a first pattern and the second perforations extending through the outer spool layer defining a second pattern, the first perforations in the inner spool layer are nonaligned from the second perforations in the outer spool layer, wherein a direct line of sight through the first perforations and second perforations is prevented and wherein the second perforations in the outer spool layer are in communication with the fluid flow paths in the inner spool layer, and wherein an unobstructed gap is defined between the inner spool layer and the outer spool layer, the gap defining a tortuous path between the first perforations in the inner spool layer and the second perforations in the outer spool layer.
