Abstract (en)

[origin: WO2005014991A1] The invention relates to an adjustment method and an adjustment device for an actuator of a valve, in particular, for a piezoelectric actuator of an injection valve for an internal combustion engine, whereby the actuator is charged to various charge states, following a given control procedure, which each correspond to a position of the valve. According to the invention, a regulation of the control procedure is carried out, depending on a regulation parameter, whereby the regulation parameter describes the charge state of the actuator and/or the valve position and, in addition, an external measured parameter, namely the pressure on the valve.
