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.

Abstract: An injection valve may comprise: an injector component having an injector body comprising a recess of the injector body extending in the direction of a longitudinal axis that can be hydraulically coupled to a high-pressure circuit of a fluid, and a nozzle needle axially displaceably disposed in the recess of the injector body, designed 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 a recess of the injector body and comprising an actuator housing in which an actuator element is disposed, and the actuator housing comprises an end face at an axial end facing the injection opening, said end face being mechanically coupled to a stage implemented in the injector body; and a ring element disposed axially between the end face and the stage.

Abstract: An explosive having cavities (16) is proposed for a pyrotechnic impact fuse (100) for high explosive shells (1). The sensitivity of the explosive lies in the class of secondary explosives, due to the cavities (16). Mechanical safety means can therefore be eliminated.
