Abstract: A metering valve includes a valve body, a valve element, a rotary servo, and a stepper motor. The valve body has a valve chamber, a fluid inlet port, a fluid outlet port, a metering valve control pressure inlet port, a servo control pressure inlet port, and a servo control pressure outlet port. The valve element is movably disposed within the valve chamber and defines therein at least a control pressure chamber and a return pressure chamber. The valve element is responsive to fluid pressure in the control pressure chamber to move between a closed position and a plurality of open positions. The rotary servo is rotatable about a rotational axis to a plurality of servo positions to thereby vary fluid pressure in the control pressure chamber. The stepper motor is responsive to commands to rotate the rotary servo to a commanded servo position.

Abstract: A fuel metering system includes a metering valve having a first inlet fluidly coupled to a source of fluid at a first pressure, a second inlet, a first outlet and a second outlet. The metering valve includes a slot, and a valve body movable to control an amount of fluid supplied to the first and second outlet. The fuel metering system includes a servo valve fluidly coupled to the second inlet and to a second source of fluid at a second pressure. The servo valve is in fluid communication with the second inlet and a body of the servo valve is movable to supply a fluid to move the valve body. The slot is configured to variably restrict the flow of the fluid through the second outlet to balance a force applied by a biasing member. The fuel metering system includes a fixed flow restriction downstream of the second outlet.
