Method for recognising the closing point of an injection valve body in a fuel injection valve and fuel injection valve

The method involves controlling an injection valve member by a solenoid valve whose anchor bolt is axially and displaceably mounted on a spring element (4). The anchor bolt is made to impact by axial force that is directly proportional to hydraulic pressure in a control chamber (3). The spring element and coils (7) of magnetic circuits are coupled by a coupling unit (6). Detectable parameters change such as change of coil voltage or coil current are caused in the magnetic circuits during elastic deformation of the spring element over the coupling unit. An independent claim is also included for a fuel injection valve for injecting fuel into a combustion chamber of an internal combustion engine.
