← TechnologyWhich system degradation accelerates when hydraulic control valves exceed hysteresis limits?
A)Fluid bulk modulus reduction
B)Actuator pressure oscillations✓
C)Reservoir heat generation
D)Pump volumetric efficiency loss
💡 Explanation
Actuator pressure oscillations increase when valve hysteresis exceeds its limit because valve spool position becomes unpredictable, driving instability via **force feedback**. Therefore, pressure oscillations increase, rather than steady-state losses, because the valves cause dynamic effects.
