Use of accumulator in hydraulic circuits.

i. A hydraulic accumulator is a device that stores the potential energy of an in compressible fluid held under pressure by an external source.

ii.The stored potential energy in the accumulator is a quick secondary source of fluid power

Spring loaded hydraulic accumulator with sketch.

A spring-loaded accumulator stores energy in the form of a compressed spring. A hydraulic fluid is pumped into the accumulator, causing the piston to move up and compress the spring as shown in Fig. . The compressed spring then applies a force on the piston that exerts a pressure on the hydraulic fluid.
