Abstract

An electromagnetic drive for implementing a linear motion includes an electromagnet having a coil, a core and an armature able to move linearly along a symmetrical axis of the core, wherein an air gap is formed between the core and the armature. With the objective of providing for simple, compact, cost-effective and flexible use of the electromagnetic drive in high-pressure systems as well as a concurrent exact positioning of the piston at any given position at optimized extension speed, it is provided for the air gap to exhibit a base and two limbs running symmetrically to the symmetrical axis as well as an essentially frustoconical cross-section in longitudinal section and for the limbs to be arranged relative to the symmetrical axis of the core so as to form an angle α.
