摘要

The fuel injection valve has a valve needle with a valve closure body on an ejection end that interacts with a valve seat on a valve seat body (5) to form a seal and several ejection openings (7). Each ejection opening is bounded by at least one first component (39) and a second component (40) that are joined together.
