Abstract

A valve for the injection of fuel has a valve body (4) which has a recess (5) in which a valve needle (6) that is movable in the axial direction is arranged. The valve needle (6) together with the valve body (4) forms an injection nozzle (7) in a downstream zone. In a closed position the valve needle (6) prevents a stream of fuel from passing through the injection nozzle (7) but otherwise leaves it unimpeded. At a downstream end the injection nozzle (7) has a deflecting element (20) so arranged that a stream of fuel is deflected from taking a predominantly upstream course from the deflecting element (20).
