Working principle of hydraulic cylinder accumulator

These pressure vessels store and release potential energy by compressing gas (typically nitrogen) as hydraulic fluid enters the accumulator under pressure. When system demand increases or pressure drops, the compressed gas expands, forcing the stored fluid back into the circuit.
