what is the output power of the hydraulic accumulator
What is Accumulator | Definition, Function, Uses, Type
An accumulator is a pressure vessel that holds hydraulic fluid and a compressible gas, typically nitrogen. The housing or shell is made of materials like steel, stainless steel, aluminum, titanium and fiber-reinforced composites. Inside, a moveable or flexible barrier—usually a piston or rubber bladder—separates the oil from the gas.

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.
