Abstract
A fuel flow control system to control fuel by regulating fuel pressure includes an inlet, an outlet, and a bypass passage. A variable orifice valve controls the flow of fuel between the inlet and the outlet in conjunction with a fixed orifice of an engine such that the relationship between pressure and fuel flow is substantially linear. A pressure-regulating valve accommodates pressure fluctuations in the system. A dual torque motor opens in proportion to the level of applied electrical current to control fuel pressure and thereby fuel flow.
