Abstract (en)
[origin: EP1947324A2] The fuel injector has a housing, in which an injection valve unit, a needle, a pressure boosting device and control valves are arranged. The former control valve controls a control chamber of the needle and latter control valve controls a differential pressure chamber of the boosting device. A high pressure connection is provided for supplying the fuel. The latter control valve is assigned with a low pressure chamber (61), which is hydraulically connected with a return port over an outlet bore, which has a hydraulic throttle (74,76) for discharging the control quantity of the boosting device.
