What are Hydraulic Accumulators? How do They Work?

Have you ever wondered how pressure energy is stored in hydraulic accumulators? Read here to learn about the working of hydraulic accumulators, the basic components of a hydraulic accumulator, and factors which limit the pressure inside the accumulator. Illustrations provided include the Kinetic Energy Recovery System or KERS system of race cars, cut-away drawings of some different styles of accumulators, and a drawing that shows the principle of operation (mechanical advantage) of a bearing weight type accumulator.
