Which outcome occurs when fluctuating pressure exceeds fluid inertia at hydraulic pump inlets?

💡 Explanation

Unstable valve spool dynamics occur when fluctuating pressure creates collapsing vapor bubbles via the mechanism named "cavitation"; because vaporization reduces damping forces, this instability results in oscillatory motion. Therefore, valve spool dynamics become erratic, rather than improved actuator response because effective damping is reduced within hydraulic lines.
