A hydraulic accumulator comprises a pressure shell, a bladder, and a rod. The pressure shell is filament wound around a leak proof 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 generally frustoconical sections connecting the ends of the shell to mid section. The bladder is tubular and expandable. A first chamber having an annular cross section for gas is formed between the rod and the bladder. A second chamber having an annular cross section for liquid is formed between the bladder and the shell. A first flow passage is formed through an end seal means communicating with the first chamber. A second flow passage is formed though an end seal means communicating with the second chamber.
