DEMAND COMPENSATED HYDRAULIC SYSTEM WITH PILOT LINE PRESSURE-MAINTAINING VALVE |
摘要 |
<p>A hydraulic system having pilot line fluid feedback from a fluid motor to valving which operates to change pump output to compensate for motor demand includes a pressure regulator valve for maintaining a predetermined minimum pressure in the pilot line. The pressure regulator valve eliminates the power wasting pressure differential which normally exists between the pump output and the fluid motor demand in demand compensated hydraulic systems.</p> |
