HYDRAULIC SYSTEM HAVING SELECTIVE SIMULTANEOUS PRESSURE AND FLOW CONTROL |
摘要 |
<p>A pressure control valve is connected to selectively supply a control pressure signal to shift a relief valve from a first low pressure mode to a second high pressure mode and for simultaneously supplying the control pressure signal to an associated variable displacement pump for reducing the relatively high output of the pump to a relatively lower output.</p> |
