FLOW COMPENSATED PROPORTIONAL BYPASS VALVE COMBINED WITH A CONTROL VALVE |
摘要 |
<p>A common regulator valve is provided for a variable displacement pump fuel metering scheme in which the common regulator valve both controls working output to a pump actuator to control displacement of the variable displacement pump and also to control bypass of excess fuel flow. The regulator valve also includes a differential piston which generates a compensation force off of the bypass flow in order to compensate for changes in spring force and flow reaction force at different system pressures and operational states. As a result, errors in the metered fuel flow can be either eliminated or substantially reduced.</p> |
