A solenoid including a substantially cylindrical hollow bobbin made of an insulating material is provided, which is mountable on a housing body and is provided with at least two relay connectors anchored in an end area of the bobbin and projecting axially therefrom, and the solenoid is also coupled to a contact element. The solenoid and the contact element are two separate components which are connectable to each other by a connecting part of the contact element attachable to the housing body, by a suitable securing method, e.g., by soldering or welding.

A fuel injector, in particular a high-pressure injector for directly injecting fuel into a combustion chamber of a mixture-compression, spark-ignition internal combustion engine, which is characterized in that on a valve seat element a conical section is formed having a valve seat surface, to which an outlet opening is immediately connected on the downstream side. The outlet opening has an intake plane, an outlet plane, and a central axis, the central point of the intake plane being offset with respect to the valve longitudinal axis and the central axis running diagonally with respect to the valve longitudinal axis. Upstream of the valve seat element a disk-shaped swirl element is arranged, which can be used both for generating a right swirl as well as a left swirl.
