Classification: CPC H | IPC H

Claim 0:
1. A linear actuation assembly comprising:
an electromagnetic coil configured to allow electric current to pass therethrough in either direction creating magnetic flux based on the electric current and its direction, said electromagnetic coil defining a center axis, an inner diameter, and first and second coil sides;
a stator cover extending over said electromagnetic coil, said stator cover fabricated from a ferromagnetic material, said stator cover defining first and second interior surfaces;
a set of magnets disposed end-to-end adjacent said first coil side of said electromagnetic coil at said inner diameter thereof, said set of magnets fixedly secured with respect to said electromagnetic coil and defining a first side and a second side of said set of magnets, wherein said first side of said set of magnets is disposed adjacent said first interior surface of said stator cover;
a ferromagnetic central ring disposed within said electromagnetic coil at said inner diameter thereof, said ferromagnetic central ring disposed adjacent said second side of said set of magnets; and
a translator disposed between said set of magnets and said central axis of said electromagnetic coil, said translator latchable between a first position disposed adjacent said first side of said set of magnets and a second position disposed adjacent said second side of said set of magnets in response to said magnetic flux and the direction in which the electric current is flowing.
