摘要：
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.
摘要（中）：
为可变排量泵燃料计量方案提供了一个通用的调节阀，其中公共调节阀都控制到泵致动器的工作输出以控制可变排量泵的位移，并且还控制过量燃料流的旁路。 调节阀还包括差动活塞，其产生离开旁路流的补偿力，以补偿在不同系统压力和操作状态下的弹簧力和流动反作用力的变化。 因此，可以消除或显着减少计量燃料流量中的误差。
