Abstract (en)

[origin: US4708116A] An injection system for a diesel engine with an injection pump for each cylinder has a delivery control valve 16 which is subjected to hydraulic control commands from a single central servohydraulic system, so that the respective spool 39 of the delivery control valve 16 connects the high pressure pump chamber 35 of the injection pump with its supply chamber 36. This bypassing connection occurs simultaneously in all the delivery control valves 16, however, movement of the delivery control spool 39 to a more fully open position takes place only if the associated injection pump is delivering fuel to the nozzle because the delivery pressure is used to complete the opening movement of the delivery control valve spool 39. In addition, a similarly operated pilot injection valve 60 is provided.
