Abstract (en)
[origin: US2010019068A1] Proposed is a fuel injector for injecting fuel into a combustion chamber of an internal combustion engine. The fuel injector has a housing in which are arranged an injection valve element with a nozzle needle, a pressure boosting device, and a first control valve, and a second control valve. The first control valve controls a control space of the nozzle needle and the second control valve controls a differential pressure space of the pressure boosting device. A first return flow connection is provided for discharging the control quantity of the control space of the nozzle needle, and a second return flow connection is provided for discharging the control quantity of the pressure boosting device. The two return flow connections are arranged on different housing parts of the housing.
