Which outcome occurs in hydraulic systems, as spool valve clearances increase due to abrasive particle contamination?

💡 Explanation

Increased internal leakage arises because the increased clearances within the valve enable greater fluid bypass, therefore volumetric efficiency plummets, rather than the system experiencing increased pressure, temperature stability, or greater resistance offered by fluid.
