Classification: CPC H  F | IPC F  H

Claim 13:
14. A solenoid valve, comprising:
at least one coil;
at least one part movable with the coil; and
a device for controlling the at least one part movable with the coil, including at least one unit configured to perform the following:
scanning a current flowing through the coil and/or a voltage applied to the coil to generate a coil signal; and
ascertaining at least one movement parameter representing an oscillatory movement of the part by using the coil signal,

wherein in the ascertaining, a speed and/or a position of the part is ascertained during the oscillatory movement as the at least one movement parameter,
changing at least one signal parameter of a dither setpoint signal for generating the oscillatory movement by comparing the at least one movement parameter to a setpoint value to adapt the oscillatory movement to the dither setpoint value,
wherein the dither setpoint signal is provided to a current controller that is configured to adapt the current flowing through the coil to a setpoint current, wherein the setpoint current includes the dither setpoint signal and a setpoint current average value.
