Abstract:
An injection valve has a valve body and a valve pin. The valve body has a metering orifice. In a closed position of the valve pin, the flow of fluid through the metering orifice is disabled and otherwise released. A control signal (ANS_SIG) for metering fluid with the injection valve is generated for a first valve pin actuator which is coupled to the valve pin to drive the valve pin. At least one first atomization signal (ZER_SIG—1) for the first and/or the second valve pin actuator is generated at least during a predetermined interval during the control of the first valve pin actuator with the control signal (AN_SIG) in such a manner that the valve pin is oscillatingly displaced relative to a position of the valve pin in response to the first atomization signal (ZER_SIG—1), the valve pin having said position in response to the control signal (ANS_SIG).
