Freudenberg Sealing Technologies offers a complete line of hydraulic accumulators which include piston, diaphragm and bladder accumulators. Whether your application is stationary or mobile, Freudenberg combines market knowledge, the latest in technology and global support for your next application. Freudenberg solutions include special weight and space-saving accumulators.
A hydraulic accumulator is a pressure vessel that performs many tasks in a hydraulic system. They are used to maintain pressure, store and recapture energy, reduce pressure peaks, power chassis suspensions, and dampen shock, vibration and pulsations.
Under gas pressure, accumulators store a volume of fluid that can be re-fed into the hydraulic system when it is needed. With a rise in pressure within the hydraulic system, the hydraulic accumulator collects the pressure fluid. The result: The gas is compressed. If the pressure falls, the compressed gas expands again and forces the stored fluid into the hydraulic circuit.
