Accumulator Information

The manual provides an extract on accumulators, noting that liquids, being incompressible, are unable to store pressure energy directly. Instead, nitrogen gas is used in the accumulators for these machines. The accumulator serves to store pressure oil for systems like the servo control, brake, and oscillating axle support. It consists of a hydraulic section and a gas section within a metal pressure vessel, with different designs, such as diaphragm, bladder, and piston accumulators.
