A variable displacement pump and pump control system therefor to pump a fluid at selected pump output flow rates having a variable displacement pump and a fluid volume displacement selection controller to select a volume of fluid to be forced from the pump inlet to the pump outlet by the rotating member during a rotation thereof. A movable lead screw is coupled to the displacement selection controller so as to be capable of altering the position thereof, and a lead screw positioner is provided for selectively moving, or preventing the moving of, the mova...
1. A variable displacement pump and pump control system therefor to pump a fluid at selected pump output flow rates in a range of pump output flow rates, the system comprising: a variable displacement pump having a rotor shaft with which to rotate a pump rotating member about an axis of rotation to force fluid that has entered a pump inlet to a pump outlet, and a fluid volume displacement selection controller to select a volume of fluid to be forced from the pump inlet to the pump outlet by the rotating member during a rotation thereof,a movable lead scr...
