Abstract:
1. Method for actuating an electromagnetic switching valve that is part of a fluid system having different operating states, comprising providing the electromagnetic switching valve that has a solenoid as well as an armature group that can be moved between a first switch position enabling a flow of fluid and a second switch position blocking the flow of fluid, wherein the armature group has a valve-closing body and an armature tappet with a magnet armature that connects to the valve-closing body with a tensile force-free frictional connection, and performing intermediate excitation for damping an overshoot of the magnet armature in at least one operating state of the fluid system between two coil excitations displacing the armature group, and the overshoot is for a duration of a free-flight phase of the armature tappet with the magnet armature against the force of an armature spring.
