ABSTRACT:
A valve for controlling the flow of fuel within a gas turbine engine is provided. The fuel flow control valve includes a valve block disposed within a sleeve, and apparatus for displacing one of the sleeve or valve block relative to the other. The sleeve includes an inlet port and an exit port. The valve block includes an inlet gate and an exit gate. One of the sleeve or the valve block may be displaced relative to the other from a closed position where the gates close the ports and thereby prevent fluid flow through the valve via the ports, to a plurality of open positions where the gates less than completely close the ports, and thereby allow fluid flow through the valve via the ports.
