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 Basics. A hydraulic accumulator is a pressure vessel containing a membrane or piston that confines and compresses an inert gas (typically nitrogen). Hydraulic fluid is held on other side of the membrane. An accumulator in a hydraulic device stores hydraulic energy much like a car battery stores electrical energy.

Hydraulic accumulators are integral components in hydraulic systems, designed to store and release energy by compressing and expanding a fluid medium, typically hydraulic oil. The choice of accumulator type depends on specific system requirements, including pressure ranges, fluid volumes, and environmental conditions.

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.

During its work, the hydraulic pump raises the pressure of the system and forces the fluid to enter the accumulator. Valves are used to control the flow of oil in and out. The piston or bladder moves and compresses the volume of the gas because fluid pressure exceeds the older pressure. This is the source of the stored energy that is to be used.
