Abstract

A device and a method for driving at least one capacitive actuator, in particular a piezoelectrically operated fuel injection valve of an internal combustion engine, by a microprocessor-controlled control circuit. The device has a charging capacitor which can be recharged by an energy source, which charges the at least one actuator via switches controlled by the control circuit, and into which the actuator is discharged again.
