Utilizing the compressibility of gas and non-compressibility of fluid (mainly oil), fluid energy is stored in or discharged out of the accumulator.
Working as a separater, the bladder separates the gas from the fluid.
The gas (Nitrogen, by all means) shall be charged in the accumulator (bladder).
When the fluid flows in to the accumulator, the precharged nitrogen gas is compressed. And, as much as the nitrogen gas is compressed, the fluid is stored in the accumulator.
Thus the fluid is stored in the accumulator as "fluid with energy", and the stored fluid is discharged out of the accumulator to let it do powerful job when necessary.
