Abstract: Various embodiments may include a method for controlling an injection process in which a fluid is conveyed to an injection element through a line system comprising: determining a time of a maximum pressure gradient caused by the injection process, based on output signals of a first pressure sensor; calculating a difference between the maximum pressure gradient and a start time; determining a propagation speed of the fluid in the line system based on the difference; determining a rigidity of the line system based on the propagation speed; determining an injected volume of the fluid based on the determined rigidity of the line system; and controlling the injection process based on the injected volume determined.

Abstract: A throttle device for controlling a fuel quantity to be supplied to a fuel injection nozzle includes a control chamber and a supply device for supplying fuel to the control chamber. The supply device includes an inlet throttle having a length selected such that a fuel flowing through the inlet throttle, when in operation, flows through the inlet throttle in a turbulent flow. An injection device including the throttle device is also provided.

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.
