  • Fuel control system
    Patent number: 4208871
    Abstract: A fuel control system has a boost pump for pumping liquid fuel to a positive displacement pump, which in turn meters the fuel to a fuel nozzle of a combustion engine. The positive displacement pump is variably driven independently of the boost pump, and includes a pressure regulator for minimizing pressure difference across the pump.
