ABSTRACT:
The flow rate of fuel to a gas turbine engine is controlled by a pivoted flapper valve which lacks the ability to shut off all flow of fuel to the engine. A secondary valve comensates for the inability of the flapper valve and shuts off the fuel flow when the flapper valve is moved to a closed but leaking position.
