FUEL SYSTEM FOR ENGINES

摘要

A fuel system for supplying fuel to a pair of injection nozzles 19 of an engine comprises a pair of pumps 9 which can only deliver half the maximum amount of fuel which may be required. Each pump 9 supplies fuel to a respective nozzle 19 when the fuel required is less than half and the system includes a pair of valves 60 which are operated to allow both pumps to deliver fuel through one nozzle when more than half the maximum amount of fuel is required, the pumps then being operated at twice the previous rate to supply fuel to the nozzle in turn.
