  • Patent number: 7327828
    Abstract: A hermetic sealing system includes a chamber enclosing a high vacuum and positioned within an ambient environment and a rotatable shaft having a first portion extending into the chamber and a second portion extending out from the chamber. A ferrofluid seal is positioned about the rotatable shaft and positioned between the first portion and the second portion, the ferrofluid seal fluidically sealing the chamber. The ferrofluid seal assembly also includes a plurality of non-magnetic conductive elements configured to reduce an operating temperature in the ferrofluid seal assembly.
