  • Patent number: 8664816
    Abstract: A permanent magnet is rotated about an axis extending between opposing north and south poles. The magnetic field of the rotated permanent magnet interacts with magnetic fields of permanent magnets carried by a shuttle for repelling and attracting the fixed permanent magnets, and providing a linear reciprocating movement of the shuttle responsive to the favorable rotary motion of the rotated permanent magnet where the force of the linear motion is captured by an energy storage device.

  • Patent number: 8336409
    Abstract: A magnetic piston includes a housing having a tapered bore extending along an axis thereof and a piston having a tapered outside wall mating with the tapered bore of the housing for providing radial and longitudinal movement within the tapered bore about a rotational axis of the piston. A shaft is connected to the piston for movement along its longitudinal axis thereof, wherein the axes of the tapered bore and piston are generally aligned along the longitudinal axis. A first set of magnets is embedded within the outside wall of the piston and a second set of magnets is embedded within a surface of a wall forming the bore of the housing. The polarity for each of the magnets within the sets provides attracting and repelling forces causing rotation of the piston relative to the housing and a linear movement of the shaft along the longitudinal axis.
