Abstract:
An injection valve includes an injector component having an injector body including a recess hydraulically coupled to a high-pressure circuit of a fluid, and a nozzle needle moveably disposed injector body recess for preventing fluid flow through at least one injection opening in a closed position, and otherwise for releasing the fluid flow; an actuator unit disposed in the injector body recess and having an actuator element disposed in an actuator housing including an end face at an axial end facing the injection opening, which end face is mechanically coupled to a stage implemented in the injector body via a ring element disposed axially between the end face and the stage. At least two radial through passages are disposed opposite each other in the ring element, designed for hydraulically coupling between a ring interior disposed within the ring element and a ring exterior disposed outside of the ring element.
