Abstract:
1. An accumulator, comprising: a tubular expandable member having a constant unstretched diameter, wherein the tubular expandable member has an open end and a closed end, wherein the tubular expandable member has a minimum yield strength of about 1000 psi, wherein the tubular expandable member has a minimum elongation of about 100%, wherein the tubular expandable member is capable of storing a minimum of 20 kJ of strain energy: a housing surrounding the tubular expandable member so that a fully expanded configuration of the tubular expandable member is contained within the housing, wherein the housing limits the radial expansion of the tubular expandable member to a point of expansion that is less than a maximum unconstrained radial expansion of the tubular expandable member, wherin the housing and the fully expanded configuration of the tubular expandable member define a space between the housing and the closed end of the tubular expandable member.
