Abstract

A process and device are disclosed for driving at least one capacitive actuator (P), in particular a piezoelectrically driven fuel injection valve of an internal combustion engine, by means of a microprocessor-controlled control circuit (ST) with a charging capacitor (C) which can be recharged by an energy source (V), which charges the at least one actuator through switches (X1 to X4) controlled by the control circuit, and into which said actuator is again discharged.
