Abstract
Constant differential pressure valves, one for each cylinder of the engine, supply liquid fuel to the injection nozzles. The liquid fuel supplied to the valves is delivered from a chamber within a metering member mounted to turn within the bore of a stationary sleeve. A plate carried by the metering member has notches on its periphery which cooperate with openings in the enclosing sleeve to form variable orifices. The metering member is turned in proportion to the rate of air flow through an air intake passage for the engine.
