ABSTRACT:
The invention relates to an injector for injecting fuel that is at high pressure into the combustion chambers of an internal combustion engine. A control part which is movable up and down by actuator actuation is received in a bore in the housing of the injector. By means of the actuator, the control part is movable into a position that enables the fuel delivery into a nozzle inlet. The valve chamber in the housing of the injector can be opened and closed during the injection phases by control edges toward the control part, while the pressure relief of the injection system is effected via slide portions disposed on the control part.
