Abstract (en)
[origin: EP1026393A2] A fuel-injection unit injector includes a nozzle or jet body (700) having at least one outlet aperture (710) for injection of fuel into a combustion chamber of a combustion engine. The nozzle or jet needle (730) is axially displaceable in a central boring and either releases or interrupts the flow of fuel to the outlet aperture (710), depending on the axial position of the needle. A control unit (600) is arranged above the nozzle or jet (700), with a guide boring (620) provided for a transmission element (630,650) for transmission of the adjustment movement of an actuator (100) on to the jet needle (730). A high pressure channel (320,610) discharges into the space formed by the guide boring (620) and the jet or nozzle (700) boring.
