Abstract (en)
[origin: EP1953773A2] The double acting electromagnetic actor (1) has an armature (2) which is arranged in the coil (71) with permanent magnets (22,25) that are magnetized in axial direction. A central disc (23) is positioned between the permanent magnets in which the armature and the coil in axial direction areas (7) are magnetized stronger or easy. A weak or non-magnetized area (8) is formed between the permanent magnets. The armature is supported in a pressure sealed pole tube (10) that is arranged in the coil.
