Control system for a fuel supply system

摘要

A control system for a fuel supply pump of the kind having first and second valves to control the timing of fuel delivery and the quantity of fuel supplied includes a governor circuit for controlling the operation of the valves, a transducer which provides a signal representing the amount of displaceable fuel in the pump at the end of the filling stroke. The control system includes means for processing the signal provided by the transducer to take account of the engine speed so that the valve is open for the correct length of time.
