Hydraulic energy recuperation from braking with the help of hydraulic accumulators helps to meet the demand for fuel-saving solutions. Freudenberg Sealing Technologies not only sharply reduced the weight of low- and high-pressure piston accumulators but – thanks to special designs and a new joining technology – achieved greater efficiency as well. Along with low costs and the lowest possible weight, the requirements involve the load capacity of the media separator with regard to gas/hydraulic oil, the influence of temperature, and the possible impairment of functionality in the event of the loss of pre-loading due to the permeation of the nitrogen through the media separator.
