ABSTRACT:
A control valve for a gas turbine engine fuel control system has a control member responsive to a servo signal. The servo signal is derived from a pilot valve which is movable against a biasing spring in response to a pressure signal dependent on engine speed, the arrangement being such that an increase in engine speed causes the pilot valve to vary the servo signal so as to reduce fuel flow to the engine. The bias applied by the spring is variable by means of an electrical actuator responsive to other engine operating parameters.
