Hydraulic Accumulators

Bag-type accumulator - a seamless rubber bag mounted within a high pressure steel cylindrical shell, usually with domed ends. A gas is charged on one side of the bag and the hydraulic fluid from the system can enter on the other. As the pump forces liquid into the shell, the fluid presses against the bag, compressing it as the pressure rises.

Hydraulic accumulator

OverviewTypes of accumulatorsFunctioning of an accumulatorSee alsoExternal links

A hydraulic accumulator is a pressure storage reservoir in which an incompressible hydraulic fluid is held under pressure that is applied by an external source of mechanical energy. The external source can be an engine, a spring, a raised weight, or a compressed gas. An accumulator enables a hydraulic system to cope with extremes of demand using a less powerful pump, to respond more quickly to a temporary demand, and to smooth out pulsations. It is a type of energy storage
