What is a Hydraulic Accumulator and How Do They Work? | BSP
A hydraulic accumulator is classed as a pressure vessel which holds hydraulic fluid and a compressible gas. Usually, the piston or rubber bladder inside the accumulator is responsible for separating the oil from the gas. The volume of gas in a hydraulic accumulator is precharged to around 80/90% of the minimum system working pressure.

Hydraulic Accumulators
2.3.6 Hydraulic Accumulator [1,22] The hydraulic accumulator, Figure 2.31, is an energy storage device in which one end is closed and another is connected to the hydraulic pipes. The hydraulic accumulator is divided into three parts: compressed gas (air chamber), piston, and hydraulic fluid (oil chamber). Figure 2.31.

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
