Title: METHOD FOR PRODUCING AN INJECTOR FOR INJECTING FUEL
Abstract:
The invention relates to a method for producing an injector (1) for injecting fuel. The injector (1) comprises the following: a closing element (5) which can be moved linearly in an axial direction (4) and a valve seat element (8) with at least one passage (9) for injecting the fuel, a valve seat (10) in which the closing element (5) lies in order to close the at least one passage (9), and a guide region (11) for guiding the closing element (5) when the closing element is moved in the axial direction (4). The method is characterized in that the valve seat (10) and the guide region (11) are hard-turned.
