An electromagnetic drive system comprises an armature (6, 6a, 6b) that can be displaced along an axis (3). The armature (6, 6a, 6b) comprises a piston-shaped section (8, 8a, 8b). Said piston-shaped section (8, 8a, 8b) is guided in a cylindrical section (2) of the stator (1). A recess (10) extends through the piston-shaped section (8, 8a, 8b) substantially in the direction of the axis (3). |
