Claim Text:
1. An in-line hydraulic accumulator system comprising: a substantially rigid, hollow, elongated cylindrical member forming the exterior of a longitudinal hydraulic fluid channel; and a hollow, elongated cylindrical compressible member longitudinally extending within the interior of the rigid member substantially along the entire length of the rigid member forming the interior of the hydraulic fluid channel, the compressible member being configured with an inside diameter and an outside diameter forming an outer periphery and to at least radially compress along its length in response to an increase in fluid pressure within the compressible member, the rigid member restricting any radial outward expansion of the entire outer periphery of the compressible member so that the inside diameter of the compressible member becomes larger upon an increase in fluid pressure to thereby accommodate more fluid therein while the outside diameter about the entire circumference of the compressible member remains constant due to the restriction of the rigid member.
