Abstract
An electromagnet drive for a valve includes a piston element. A housing comprises an electromagnetic circuit, a coil wound onto a coil former, an armature mounted to move between a first and second end position to act on the piston element, a core, and a magnetisable return device. The core and/or the magnetisable return device comprises an adjusting bore. The core or the magnetisable return device comprises a substantially circumferential cutout in a region of the adjusting bore on a side facing the coil. A fixing device fixes the armature in a non-energized state. An adjusting device adjusts a magnetic force. The adjusting device comprises an adjusting screw which influences a profile of magnetic field lines. The adjusting screw is insertable into the adjusting bore of the core or the magnetisable return device in a direction of the armature. Energizing the coil moves the armature into the first or second end position.
