ABSTRACT: Accumulators are used in virtually any hydraulic system. Like a capacitor or battery serving in an electric circuit or a flywheel in a mechanic system, they are designed to store hydrostatic energy which can then be made available again upon demand. While the capacitive effect of hydraulic accumulators has been sufficiently described, there remains scope for flow optimization particularly with regard to highly dynamic accumulator charging and discharging process.
