How does a hydraulic accumulator work?

In operation, the hydraulic pump raises system pressure and forces fluid to enter the accumulator. (Valves control oil flow in and out.) The piston or bladder moves and compresses the gas volume because fluid pressure exceeds the precharge pressure. This is the source of stored energy. Movement stops when system and gas pressures are …
