摘要

The fuel injection valve has a housing part (1) with an injection opening (2) in a form of radial extending bore. A valve closure element (3) is formed in spherical shape, and the injection opening is formed as a bore. The injection opening serves as a valve seat (5) for the valve closure element. A rotary mounted actuating element (4) has a cylindrical or conical section formed as a running surface (7) for the spherical valve closure element.
