Hydraulic accumulators

Hydraulic accumulators, also known as hydropneumatic accumulators or pressure accumulators, are used in hydraulic systems to maintain fluid pressure, store and recapture fluid energy, reduce pressure peaks, power chassis suspensions, and dampen shock, vibration and pulsations. Most common fluid hydro-pneumatic accumulators are used with is hydraulic oil.

Under precharge pressure (nitrogen gas), the hydraulic accumulator stores a volume of fluid that can be re-fed into the hydraulic circuit when it is needed. With a rise in pressure within the hydraulic system, the hydro-pneumatic accumulator collects the pressure fluid and the gas is compressed. If system pressure falls, the compressed gas expands again and forces the stored fluid into the hydraulic circuit. The hydropneumatic accumulator guarantees a fast reaction in case of pressure drop.

Diaphragm accumulators

Diaphragm accumulators are the smaller ones, from 0,07 liter up to 3,5 liter, with fluid operating pressure up to 210/250 bar or 330/350 bar. Thanks to the ECO diaphragm, operating temperature can go from -40°C up to +80°C. A diaphragm accumulator is refillable through the M28x1,5 gas port, but cannot be repaired due to its welded shell. Fortunately accumulator price is low and the complete range of sizes are available in stock.
