Accumulator is a device used specifically for storage of liquid under pressure. As liquids, for all practical purposes, are incompressible, this objective is achieved by utilizing the compressibility of gases. A flexible rubber separator i.e., diaphragm is fitted into the accumulator shell. An inert gas - nitrogen - is filled into the diaphragm through a pressure valve to a pressure P . The diaphragm expands, filling the entire volume V of the accumulator shell. When the system (circuit) pressure P is higher than the gas 1 precharge pressure P , the liquid enters the shell and the diaphragm is compressed reducing the gas volume to V .1 Should the liquid pressure rise to P , the volume of gas 2 reduces to V with an attendant rise in pressure, thus 2 balancing the Liquid pressure. A potential energy is now stored in the accumulator to be utilized whenever needed.

Fluids are practically incompressible and cannot therefore store pressure energy. The compressibility of a gas is utilised in hydraulic accumulators for storing fluids. HYDAC diaphragm accumulators are based on this principle, using nitrogen as the compressible medium.Diaphragm accumulators consist of a fluid section and a gas section with the diaphragm acting as a gas-tight separation element.The fluid section is connected to the hydraulic circuit so that the diaphragm accumulator draws in fluid when the pressure increases and the gas is compressed. When the pressure drops, the compressed gas expands and forces the stored fluid into the circuit. Set into the base of the diaphragm is a valve poppet. This shuts off the hydraulic outlet when the accumulator is completely empty and thus prevents damage to the diaphragm.
