Which instability increases when a hydraulic actuator's accumulator pressure is too low?

💡 Explanation

Low accumulator pressure increases the risk of hydraulic pressure oscillation induced cavitation because the accumulator cannot dampen these waves effectively; therefore cavitation becomes more probable, rather than hysteresis changes which are related to valve design.
