Abstract
An electromagnetically actuatable valve, e.g., a fuel injector for fuel injection systems, includes an electromagnetic actuating element having a solenoid, a fixed core, a valve jacket, and a movable armature for actuating a valve closing body, which cooperates with a valve seat surface provided on a valve seat body. In addition, the valve has a restoring spring for resetting the valve closing body to its resting position on the valve seat surface. The restoring spring and an internal longitudinal bore hole of the armature are paired in such a way that the armature is guided during its axial movement only along the restoring spring.

An electromagnetically actuatable valve, comprising:
- a valve seat body having a valve seat surface;
- a valve closing body configured to cooperate with the valve seat surface on the valve seat body;
- an excitable actuator in the form of an electromagnetic circuit including a solenoid, an internal pole, an external magnetic circuit component and a movable armature, wherein the movable armature is configured to operate the valve closing body;
- and
- a restoring spring configured to restore the valve closing body to a resting position on the valve seat surface, wherein the restoring spring and an internal longitudinal bore hole of the movable armature are operatively paired such that axial movement of the movable armature is guided only along the restoring spring.
