as shown in fig5 b first fluid chamber 16 a third fluid chamber 16 c and first air chamber 17 a are deformed as shown as a result some fluid contained in first fluid chamber 16 a and third fluid chamber 16 c is sent via first channel 18 a and second channel 18 b respectively to second fluid chamber 16 b and fourth fluid chamber 16 d however due to first air chamber 17 a the chamber walls 20 are deformed inward toward first air chamber 17 a and second air chamber 17 b however this can vary depending on the elastic shape due to the compliance of walls 20 because of first air chamber 17 a and second air chamber 17 b the multiple chamber piston according to the present invention is able to attenuate lower frequencies in fig6 the kdynamic response for the multiple chamber piston is shown as a in the legend as can be seen two distinct loss angle peaks are achievable through varying the lengths and areas of channels 18 a and 18 b and the compliance of the walls referring now to fig4 a second embodiment of the present invention is shown and described in fig4 orifices 22 passes through outer metal casing 12 to allow air to pass into and out of first air chamber 17 a and second air chamber 17 b this in turn.
