20090121558 | Flexible Electromagnetic Valve Actuator Modeling and Performance - The system contains a first planar permanent magnet having a first direction of magnetization and a first opening formed therein. A second planar permanent magnet has a second direction of magnetization and a second opening formed therein. The second opening is axially aligned with the first opening. The direction of magnetization of the first planar permanent magnet opposes the direction of magnetization of the second planar permanent magnet. A plurality of stationary coils are provided, wherein at least one of the stationary coils is located within the first opening and at least one of the stationary coils is located within the second opening. A pair of extension members traverses the first opening and the second opening. A magnetizable slug is integral with each of the extension members. | 05-14-2009 |
