Abstract

See full text

An electromagnetic drive for a valve includes a housing comprising at least one electromagnetic circuit comprising a coil wound onto a coil support, a valve closing member, at least one core, at least one magnetizable reflux member, an armature having an annular shape at least on a side facing away from the valve closing member, an adjustment device having an adjustment screw, and a device to fix the armature in a non-energized state. The armature moves between a first end position and a second end position so as to act at least indirectly on the valve closing member. The adjustment device adjusts a magnetic force. The adjustment screw is insertable through the at least the magnetizable reflux member or through the core into the armature. Supplying the coil with an electric current causes the armature to move into the first end position or into the second end position.
