摘要：
A fuel system comprises a fuel pump operable to deliver fuel through a supply line to a pressure raising valve, the pressure raising valve including a control chamber, the fuel pressure within the control chamber controlling a minimum pump pressure differential, and an actuator control servo-valve operable to control the supply of fuel from the supply line to an actuator control line, wherein the actuator control servo-valve further controls the pressure of fuel applied to the control chamber of the pressure raising valve.
