Abstract (en)
[origin: EP0859380A2] The double acting proportional electro magnetic actuator system Ä11Ü has an armature Ä33Ü with an axial in line displacement sensor Ä12Ü. The actuator has two coils Ä18,19Ü with a magnet flux conducting centre disc Ä35Ü with stator poles . Poles are formed on the armature. A spring Ä47Ü provides a fail safe position for the valve. An additional rotary motion is provided by the excitation of both coils
