← TechnologyWhich behavior arises when a hydraulic relief valve experiences excessive dither frequency?
A)Increased system pressure oscillations✓
B)Decreased actuator response time
C)Elevated hydraulic fluid temperature
D)Reduced valve spool displacement
💡 Explanation
When a relief valve experiences excessive dither frequency, resonance occurs because of the rapid opening and closing cycles exciting natural frequencies within the hydraulic system, which leads to pressure oscillations. Therefore, increased system pressure oscillations result, rather than decreased response time, elevated temperature, or reduced spool displacement, conditions requiring different excitations.
