Abstract (en)
[origin: EP0936636A2] The actuator has an opening magnet (22) and a closing magnet (23) with coils (4,12) within cores (5,11). The produced magnetic field (20,21) operates upon an armature plate (10). The core elements have diffusion directions (1-3,17-19) with different magnetic materials (6-8,13-15). The materials which are nearer to the coil in the diffusion direction have a smaller saturation flux density, which is achieved with a smaller field strength than the materials further from the coils.
