Hydraulic accumulator

Accumulator which stores a fluid under pressure and is therefore able to release hydraulic energy. Pressurisation is mainly based on gas pressure (air, nitrogen, "hydropneumatic accumulator") and, more rarely, springs or weights (spring accumulator, weighted accumulator).The latter is the only accumulator which keeps the pressure constant during withdrawal of the volume.
