How does an accumulator work in a hydraulic system

The operating principle of a hydraulic system accumulator is based on the principle of energy storage. When the hydraulic system is under pressure, fluid enters the accumulator and compresses the gas, which in turn enables the accumulator to store potential energy. This energy can be released when needed to enhance the system''s performance or
