An accumulator is a device that is used to store energy in a hydraulic system. In the case of excavators, hydraulic accumulators are used to store hydraulic energy that is generated during the digging process. This energy can then be released when needed, allowing the excavator to perform tasks more efficiently.

A hydraulic accumulator is a pressure storage reservoir in which an incompressible hydraulic fluid is held under pressure that is applied by an external source of mechanical energy. The external source can be an engine, a spring, a raised weight, or a compressed gas. An accumulator enables a hydraulic system to cope with extremes of demand using a less powerful pump, to respond more quickly to a temporary demand, and to smooth out pulsations. It is a type of energy storage
