Abstract (en)
[origin: EP0215296A1] A helium charged accumulator is disclosed for use in hydraulic fluid pressure systems. The size of the accumulator is optimized for particular operating conditions of specific applications of the hydraulic systems by means of a formula. The formula has, as its terms, the volume of the hydraulic fluid required to power a given device, the compressibility factor of the particular gas used and the temperature and pressure of the gas at the beginning of, during, and at the end of the operation cycle of the accumulator.
