Abstract
The apparatus and method of regulating a control valve for a Diesel injection system comprises a fuel injector having a pressure amplifier preceded by the control valve (10), the slide (20) of the control valve (10) being moved by two spatially separated magnet coils (30, 32). During an electrical triggering of one of the two magnet coils (30, 32) with a control current, the respective other magnet coil (32, 30) is switched as a sensor, detecting the current induced in the sensor by a motion of the valve slide (20).
