Abstract:
1. A device suitable for moving a body along a substantially linear path between a first predetermined position and a second predetermined position, said device comprising: a first electromagnet which has a first moving core physically secured, directly or indirectly, to said body at a first junction with the body and arranged to have a first axis of action on said body that is substantially parallel to said linear path, said first core being arranged to travel through a first stroke; a second electromagnet which has a second moving core physically secured, directly or indirectly, to said body at a second junction with the body and arranged to have a second axis of action on said body that is substantially parallel to said linear path, said second core being arranged to travel through a second stroke, said first stroke and said second stroke being of a same length, said second junction being distinct from the first junction; and a permanent magnet disposed to cooperate magnetically with said first core when the body is in the first predetermined position; wherein the first electromagnet extends along the first axis of action and the second electromagnet extends along the second axis of action; and the first axis of action is distinct from the second axis of action.
