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.

[ We claim:] [1.] A valve for controlling the flow of fuel within a gas turbine engine comprising:a sleeve, having an inlet port, an exit port, and an internal cavity in communication with said inlet and exit ports;a valve block, having an inlet gate and an exit gate; andmeans for measuring fluid pressure within said internal cavity;wherein one of said sleeve or valve block can be selectively displaced relative to the other of said sleeve or valve block from a closed position, where said gates close said ports and thereby prevent fluid flow through said valve via said ports, to a plurality of open positions where said gates allow fluid flow through said valve via said ports;wherein in said plurality of open positions, fluid enters said valve via said inlet port and passes into said internal cavity, and fluid exits said valve via said exit port.
