FUEL CONTROL SYSTEM AND APPARATUS FOR GAS TURBINE ENGINE Abstract: The disclosure embraces a fuel control system and apparatus for delivering or supplying liquid fuel to a gas turbine engine comprising a body construction (12) in which is contained a first diaphragm-actuated fuel control valve arrangement (40) for regulating fuel flow to the turbine engine for normal engine operation, a second diaphragm-actuated fuel control valve arrangement (42) for regulating fuel flow to the turbine engine for engine idling operation, the diaphragm-actuated valve arrangements (40) and (42) being responsive to the difference between the engine burner pressure and the compressor discharge pressure. A third diaphragm-actuated fuel control valve arrange- ment (44) is provided for supplying fuel to the turbine engine for engine starting purposes. The system and arrangement includes an operator-controlled member (80) for varying resilient biasing pressure on a relieve valve (86) for varying the compressor dis- charge pressure effective on the first diaphragm- actuated valve arrangement for regulating the speed of the turbine engine.
