← TechnologyWhich outcome occurs when an axial piston pump swash-plate control valve oscillates?
A)Flow ripple and pressure pulsations✓
B)Reduced servo-motor control accuracy
C)Increased hydraulic fluid temperature
D)Pump bearing structural fatigue failure
💡 Explanation
Pressure and flow regulation malfunctions from Limit Cycle Oscillation of the swash-plate control valve, because this causes periodic disturbances in the output flow rather than maintaining a stable, constant flow. Therefore, flow ripple emerges, rather than controlled flow.
