Abstract
A fuel injection valve for internal combustion engines having a valve member axially displaceably guided in a bore of a valve body, the end of which valve member toward the combustion chamber has a valve sealing face that to control the passage of fuel to an injection opening discharging into the combustion chamber of the engine cooperates with a valve seat provided on the end of the bore toward the combustion chamber, and having a guide face on the end of the valve member remote from the combustion chamber, which guide face guides the valve member slidably displaceably in the bore. In the guide face of the valve member, many recesses are provided, which center the valve member hydraulically in the bore.
