Hydraulic Accumulators: What Are They and Why Do We Need
Essentially, an accumulator is a vessel containing a bladder and gas so that as the bladder fills with pressurized hydraulic fluid, the gas compresses inside the vessel. When the fluid in the accumulator is released, the compressed gas pushes out the fluid. The accumulator will come preloaded, which means a minimum pressure is

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

The weight-loaded accumulator in Figure 16-1 does not lose pressure until the ram bottoms out. Thus 100% of the fluid is useful at full system pressure. The major drawback to weight-loaded accumulators is their physical size. They take up a lot of space and are very heavy if much volume is required.
