Abstract
The invention relates to a fuel injector for the operation of an internal combustion engine, having an injector body. An inlet bore of the injector body connects a conical pressure connection to a valve chamber for supplying highly pressurized fuel. The valve chamber is placed along a longitudinal center axis of the injector body and above a nozzle needle. According to the invention, the inlet bore further has a fan-shaped contour starting at the conical pressure connection along the extension thereof, the contour having a fan angle and a variable cross-section in the shape similar to an elongated hole.
