Abstract
A guided-float accumulator suitable for use with a hydraulic system for an oil well blowout preventer utilizes an array of float elements of syntactic foam material. The float elements are sequentially inserted into the pressure vessel which forms the accumulator proper, and are then manipulated from the exterior of the vessel to be interlocked into a float array.
