← TechnologyWhich outcome occurs when bypass valve hysteresis increases?
A)Limit cycle pressure oscillations increase✓
B)Actuator slew rate becomes overdamped
C)Component stress from vibration lowers
D)Hydraulic efficiency increases dramatically
💡 Explanation
Increased valve hysteresis deadband induces sustained oscillations, because the valve's delayed response contributes to limit cycle oscillations with excess actuation; therefore pressure cycles persist rather than a stable pressure setting because the effect becomes self-reinforcing in the bypass.
