Woody, J C

The disclosure embraces a fuel control system and apparatus for delivering or supplying liquid fuel to a gas turbine engine comprising a body construction in which is contained a first diaphragm-actuated fuel control valve arrangement for regulating fuel flow to the turbine engine for normal engine operation, a second diaphragm-actuated fuel control valve arrangement for regulating fuel flow to the turbine engine for engine idling operation, the diaphragm-atuated valve arrangements and being responsive to the difference between the engine burner pressure and the compressor discharge pressure. A third diaphragm-actuated fuel control valve arrangement is provided for supplying fuel to the turbine engine for engine starting purposes. The system and arrangement includes an operator-controlled member for varying resilient biasing pressure on a relief valve for varying the compressor discharge pressure effective on the first diaphragm-actuated valve arrangement for regulating the speed of the turbine engine.
