first air chamber 17 a and second air chamber 17 b each of the above described chambers generally begin at the outer surface of bushing 14 passing through second layer 50 and into core 52 and extend inward in a substantially parallel fashion as a result when the multiple chamber piston is assembled each of the above described chambers in bushing 14 except 17 a and 17 b are sealed by outer metal casing 12 connecting first fluid chamber 16 a and second fluid chamber 16 b is first channel 18 a likewise connecting third fluid chamber 16 c and fourth fluid chamber 16 d is second channel 18 b first channel 18 a and second channel 18 b are formed by cutting portions out of outermost layer 18 as a result these channels are bounded by the cut areas of outermost layer 18 and second layer 50 preferably each channel 18 a and 18 b extends radially around the bushing 14 proximate the surface thereof these channels serve to connect each chamber to allow fluid flow therebetween as can be understood providing each channels 18 a and 18 b with different cross sectional areas will serve to provide two different attenuation frequencies as each allows a different volume of fluid to flow therethrough referring.
