A hydraulic accumulator is a device that stores pressurized hydraulic fluid. It consists of a cylinder, a piston, and a fluid reservoir. When the hydraulic system generates excess fluid, the piston in the accumulator compresses a gas or a spring, storing the energy until it is needed. Hydraulic accumulators are commonly used in industrial
