Abstract:Pressure pulsation in oil-hydraulic system is generated due to the use of a positive displacement pump and it causes oscillation, noise and so on. An accumulator is generally employed to suppress the pressure pulsation. However, accumulator needs regular maintenance to prevent its performance deterioration due to gas leakage from it. Furthermore, there is a case where it is difficult to make the size of oil-hydraulic system compact due to the size of accumulator. Therefore, it seems to be necessary for an inno… Show more
