<p>A hydraulic accumulator comprises a pressure shell, a bladder, and a rod. The pressure shell is filament wound around a leak proof 5 barrier/mold. The bladder is tubular and carried by the rod. The rod extends though the pressure shell and seals to the ends of the shell. The shell has a first generally cylindrical section positioned at the first end and a second generally cylindrical section positioned at the second end. A third generally cylindrical mid section is positioned 10 between the first end and the second end. A first generally frustoconical section connects the first end section to the mid section and a second generally fnjstoconical section connects the second end section to the mid section. The bladder is tubular and expandable. A first chamber having an annular cross section for gas is formed 15 between the rod and the bladder.</p> |
