ABSTRACT:
Apparatus for converting the variations in magnetic force between two magnets, one rotating and one non-rotating, into reciprocating linear motion of an associated device, said apparatus including a motor driven rotatable permanent bar magnet and a non-rotatable permanent bar magnet disposed adjacent thereto and mounted for linear movement, and having an actuator shaft attached thereto, whereby the alternately attracting and repelling magnetic forces between the two magnets are effective to reciprocate the actuator shaft.
