The oil side has an input port through which ...
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.
nitrogen gas to smallest gas volume. 3 During operation, the minimum working system pressure, P 1, is reached and the gas volume is now V 1. This is often called "discharging" the accumulator. • V 1 is the maximum gas volume during hydraulic system operation and correlates to the smallest possible fluid volume inside the accumulator ...
