| 摘要 |
The invention relates to a common rail injector for injecting fuel in a common rail injection system of an internal combustion engine, in particular a large diesel engine, having an injector housing which communicates with a central high-pressure reservoir and in which a nozzle needle can move axially counter to the initial stress of a nozzle spring which is contained in a nozzle spring chamber, in order to adjust the injection onset and the injection quantity as a function of the position of a 3/2-way valve. In order to improve the damping behavior in a common rail injection system, an injector pressure reservoir is integrated into the injector housing and communicates with the central high-pressure reservoir independent of the position of the 3/2-way valve.
