ABSTRACT:
A fuel injector of a Diesel engine is supplied with a boosted supply of fuel from a booster and operated to start and terminate a fuel injection by a hydraulically controlled nozzle needle actuator. A valving unit is controlled to selectively communicate compressed operating fluid to the booster so that the boosted supply of fuel reaches the fuel injector. The valving unit comprises a pair of poppet type valves each of which is operated by a solenoid operated pilot valve, thereby attaining high speed operation due to a high frequency of switching actions and accommodating a large flow rate of fluid. A manually or automatically adjustable stop is associated with each of the poppet type valves to control the flow rate of fluid through the valve to the booster, which dictates the pressure of fuel injection from the injector.
