Abstract
Solenoid valve system having a solenoid valve and further having a controller, wherein the solenoid valve includes a valve housing through which a fluid channel passes, in which fluid channel a valve member for temporarily sealing a valve seat formed in the fluid channel is movably accommodated, and including a solenoid drive which has a magnetic circuit with a solenoid coil and a linear-movable armature which is coupled to the valve member, the controller provides a coil current to the solenoid coil and is connected to a sensor which provides a sensor signal which is dependent on a movement of the armature, the controller analyzes the sensor signal to determine a movement of the armature, wherein the controller provides a closed loop control for the coil current in the presence of the armature movement.
