The first accumulators for William Armstrong''s hydraulic dock machinery were simple raised water towers. Water was pumped to a tank at the top of these towers by steam pumps. When dock machinery required hydraulic power, the hydrostatic head of the water''s height above ground provided the necessary pressure.
Hydraulic accumulators are energy storage devices. Analogous to rechargeable batteries in electrical systems, they store and discharge energy in the form of pressurized fluid and are often used to …
