Hydraulic Accumulator is a device which is used to accumulate or store pressure energy of a fluid. This energy may be supplied at a later stage to drive a machine tool for any sudden and intermittent operation just like Lifting Load, Hydraulic Crane etc.
Basically Accumulater acts like a flywheel. It stores energy when there is need of energy and supplies it when there is shortage.
