Hydraulic Accumulator

The HA is a bladder type accumulator. Maximum bladder internal volume is 0.6 liters (maximum gas
volumetric capacity).
Its operation is based on the considerable difference in compressibility between a gas and a liquid:
fluids are practically incompressible and cannot therefore store pressure energy, so the nitrogen gas is used as a storage medium, enabling a large quantity of energy to be stored in an extremely compact form.
