The name hydropneumatic accumulator covers those hydraulic products that are designed specifically for the storage (accumulation) of liquid under pressure. However, because of the improvements in design of equipment, which has grown from the storage devices, other functions have become loosely associated with the name Accumulator. These other types of units should more properly be called by their function, e.g. – Pulsation Dampers, Liquid Borne Noise Silencers, Line Shock Alleviators, Pump Controllers, Transfer Barriers, etc. More about accumulators...

Normally the piston is "free", but in some cases may be connected to a conventional piston rod. Design and construction is relatively straightforward and the type can be made in a wide range of sizes. Cost is, however, relatively high. It is particularly suited for high pressure systems since cylinder stresses are readily determined and standard hydraulic quality cylinder tubes can be employed for the barrels. Construction can follow that of hydraulic cylinders, with tie rod assembly for higher pressures or heavy duties. However, it is necessary to make provisions to prevent disassembly of the end covers when either the fluid or gas side of the accumulator is under pressure. More about accumulators...
