First claim
Opening claim text (preview).
The invention claimed is: 1. A core structure for an electromagnetic actuator, comprising: an electrically conductive magnetic core component having a magnetic axis, an outer surface between axially opposite ends and at least one slit arranged between said axially opposite ends through the outer surface, wherein said at least one slit is arranged helically to said magnetic axis. 2. A core structure for an electromagnetic actuator, comprising: an annular electrically conductive magnetic core component having a magnetic axis, and inner and an outer surfaces between axially opposite ends, and at least one slit arranged between said axially opposite ends through at least one of the inner and outer surfaces, wherein said at least one slit is arranged helically to said magnetic axis. 3. The core structure of claim 2 , wherein said at least one slit comprises a slot. 4. The core structure of claim 2 , wherein said at least one slit comprises one slot and a plurality of slits. 5. The core structure of claim 2 , further comprising at least one slit arranged between said axially opposite ends through the inner surface. 6. The core structure of claim 2 , wherein said at least one slit is arranged parallel to said magnetic axis. 7. An electromagnetic fuel injector, comprising: an annular electrically conductive magnetic core component having a magnetic axis, and inner and an outer surfaces between first and second axially opposite ends, and at least one slit arranged between said axially opposite ends through at least one of the inner and outer surfaces, wherein said annular electrically conductive magnetic core component comprises at least one of a guide ring, an armature, a pintle, and a magnetic core. 8. The electromagnetic fuel injector of claim 7 wherein said at least one slit comprises a slot. 9. The electromagnetic fuel injector of claim 7 wherein said at least one slit comprises one slot and a plurality of slits. 10. An electromagnetic fuel injector, comprising: an annular electrically conductive magnetic core component having a magnetic axis, and inner and an outer surfaces between axially opposite ends, and at least one slit arranged between said axially opposite ends through at least one of the inner and outer surfaces, wherein said annular electrically conductive magnetic core component comprises at least one of a guide ring, an armature, a pintle, and a magnetic core. 11. The core structure of claim 10 , wherein said at least one slit comprises a slot. 12. The core structure of claim 10 , wherein said at least one slit comprises one slot and a plurality of slits. 13. The core structure of claim 10 , wherein said at least one slit comprises a plurality of slits arranged on both the inner and outer surfaces of the core. 14. The core structure of claim 10 , wherein said at least one slit is arranged parallel to said magnetic axis.
