  • Magnetic actuator, system and method
    Patent number: 11248718
    Abstract: A magnetic actuator including a housing having an inside surface, an outside surface and a body between the inside and outside surfaces; a mobile component movable relative to the housing; a magnet piston chamber disposed within the body; a magnet piston disposed in the magnet piston chamber and disposed to effect movement of the mobile component relative to the housing, the magnet piston having a magnetic field; a prime piston chamber disposed within the body in spaced relationship to the magnet piston chamber and segregated from the magnet piston chamber by material of the body, there being no fluid path between the magnet piston chamber and the prime piston chamber; a prime piston disposed in the prime piston chamber, the prime piston having a magnetic field; wherein the magnet piston is responsive to movement of the prime piston by magnetic interaction between the magnet piston and the prime piston.
