Nozzle assembly for an injection valve and injection valve

An injection valve, comprising:

• a nozzle assembly including:
• a nozzle body having a nozzle body recess and at least one injection opening, wherein the nozzle body recess is configured for hydraulically coupling to a high-pressure circuit of a fluid, and the injection opening is hydraulically coupled to the nozzle body recess, and
• at least one nozzle needle arranged in an axially movable manner in the nozzle body recess, and having a central axis and a needle tip,
• wherein a sealing seat is formed on a wall of the nozzle body recess and a seat region is formed on the needle tip,
• wherein the seat region interacts with the sealing seat such that the nozzle needle, in a closed position, prevents a fluid flow through the at least one injection opening and, in an open position, permits the fluid flow through the at least one injection opening,
• wherein downstream of the sealing seat and the seat region, turbulence elements formed as microstructures are arranged on at least one of the needle tip and a surface region of the nozzle body recess, such that the recesses and/or protrusion generate a predefined intensity of turbulence of the fluid in the at least one injection opening, wherein the turbulence elements include at least one of recesses and protrusions, and
• an actuator configured to act on the nozzle assembly.
