Abstract (en)
[origin: EP1983186A2] The injector (10) has a nozzle module (12), a throttle plate (14), and a holding body (18). An actuator module such as piezo actuator, is accommodated in a fuel free space within the holding body. A control valve is pressure compensated, and includes a valve body, which contains a passage opening into which a guide pin is guided. The guide pin is supplied within a high pressure area with fuel, which stays under system pressure.
