Abstract
A solenoid valve includes an operating magnet which controls movement of an armature against the effect of a valve spring, which armature in turn controls the movement of a valve member connected with the armature by a sliding connection. The armature has a control member which can be introduced into a coil with an exciter winding. The coil is part of an electronic circuit provided for control of the cross section of the fluid flow passage of the valve.
