Abstract
The disclosure illustrates an electronically controlled fuel pump in which a bypass valve regulates its output pressure to a predetermined level above a control pressure. A downstream throttling valve re-regulates the pressure to a predetermined level below a control pressure. The control pressure is established by an electro-hydraulic valve which is, in turn, fed with signals with a microprocessor to provide appropriate control. The use of the control pressure in effect causes a servo action and utilizes the pressure of the fuel to manipulate the valve and minimize the power requirement of the electro-hydraulic valve.
