Title: MAGNETIC SEAL FOR MAGNETICALLY-RESPONSIVE DEVICES, SYSTEMS, AND METHODS
Abstract:
A magnetically-responsive device (100) having a magnetic seal (160,170) to retain magnetically responsive material within a defined space (150) is provided. The magnetically-responsive device (100) has a shaft (110), a rotor (130), a magnetic field generator (145), a magnetically-responsive medium and a magnetic seal (160,170). The seal (160,170) is preferably a non-contact seal (160,170) that does not deteriorate over time and generates little to no resistance.
