Accumulator

An accumulator that is connected to a source of hydraulic fluid, comprising a movable barrier which separates the hydraulic fluid from a compartment containing two distinct energy absorbing medium that are a first energy absorbing medium and a second energy absorbing media, wherein said movable barrier, when acted upon by an increase in pressure of the hydraulic fluid, will move in a first direction whereupon it will initially contact the first energy absorbing medium to thereby begin compressing said first energy absorbing medium and, when it moves further in said first direction, will contact the second energy absorbing medium to thereby begin compressing said second energy absorbing medium while still compressing said first energy absorbing medium.
