摘要：High efficiency, high pressure fixed displacement pump systems and methods ofcontrol. A typical application is for engine driven high pressure pumps for powering loadssuch as fuel injectors and/or hydraulic engine valve actuators. The pump systems includea control valve controllably coupling the pump output back to the pump input to stopthe pumping when the desired pressure of the output is reached. Reinitiating pumping anincrement in crankshaft angle before a load event based in the increment in pressureneeded to reach the desired pressure at the crankshaft angle of the load event providesa simple control algorithm assuring accurate repeatability in the pressure at the

beginning of a load event. Pumping throughout the load event minimizes the decrease inpressure during the load event. Providing underlap in the control valve minimizes

pressure peaks and maximizes efficiently when starting and stopping the pumping action.Various embodiments are disclosed.
