Abstract (en)
[origin: EP1918575A1] An injector (2) for dosing fluid comprises an injector body (4) having a recess (8) and an injection nozzle (18) at a tip (20) of the injector body (4). A needle (15) is arranged in the recess (8) of the injector body (4) movable in axial direction. The needle (15) prevents a fluid flow through the injection nozzle (18) in a closed position of the needle (15) and otherwise enables the fluid flow through the injection nozzle (18). An actor arrangement is arranged in the recess (8) of the injector body (4) and coupled to the needle (15) at a first axial end (13) of the actor arrangement for moving the needle (15). The actor arrangement is coupled with the injector body (4) at a second axial end (37) of the actor arrangement in such a way that the second axial end (37) is fixed relative to the injector body 4. Further, the actor arrangement comprises a piezo-actuator (10) and a calibration shim (44) for calibrating the injector (2).
