Claims14
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.
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.
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.
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.
