Function:

Hydraulic accumulators are an essential component for the optimum operation of a hydraulic circuit. The accumulator enables:

• Energy Storage: Saves energy without loss and redistributes when required, reducing installed power.
• Pressure Compensation: Absorbs pressure spikes from pumps or other components to control pressure and flow rates in the hydraulic circuit.
• Volume Control: Absorbs fluid volume variations induced by temperature changes in a closed hydraulic circuit and maintains a rated pressure.
• Emergency Energy Storage: In case of failure of the main energy source, these accumulators can provide sufficient energy to complete an operation or realize a full hydraulic cycle.
• Hydraulic Spring/Shock Absorber: Acts as a gas spring, suppressing shocks and vibrations in hydraulic systems of lifting vehicles (e.g., Forklift trucks) and maintaining real suspension of the load on a gas spring.
