Abstract: A fuel feed control comprising a device for a metered fuel supply to the combustion chamber of a gas-turbine engine, a valve to maintain a preset fuel pressure differential across the actuator element of the metering device, and a corrector of the rate of fuel feed to the combustion chamber depending upon the ambient air temperature. The actuator element, corrector and valve are mounted in respective parallel passageways which connect the fuel pump with the combustion chamber of the gas-turbine engine.

Abstract: Fuel distribution apparatus comprising a jet and two valves arranged in parallel in a passage connecting the fuel delivery line to the main manifold. The first valve maintains a predetermined pilot manifold pressure required for steady combustion of the fuel delivered through the pilot manifold. The second valve has a flow area greater than that of the jet and the first valve. When engine speed is reached at which the combustion of the fuel delivered through the main manifold becomes steady, the second valve opens and allows fuel to flow therethrough, effectively bypassing the jet and the first valve.
