How Bladder Accumulator Works

Bladder Accumulator:

• A Bladder (Compressed Gas) accumulator consists of a Cylinder with two chambers which is separated by an elastic diaphragm, a totally enclosed bladder or a floating piston.

• One Chamber is contains hydraulic fluid and is connected to the hydraulic line. 

• The other chamber contains an inert gas (Typically Nitrogen) under pressure that provides the compressive force on the hydraulic fluid.

• Inert Gas Used because oxygen and oil can form an explosive mixture when combined under high pressure.

• As the volume of the compressed gas changes, the pressure of the gas and the pressure on the fluid changes inversely.
