 Magnetic fluid seal apparatus

Details
Inventors: Yokouchi, Atsushi; Matsunaga, Shigeki;
Assignee:
Primary Examiner: Cuchlinski, Jr.; William A.
Assistant Examiner: DePumpo; Daniel G.
Attorney, Agent or Firm:

A magnetic fluid seal is improved by coating parts of the sealing mechanism and/or adjacent surfaces with a fluorine-containing surfactant as an oil-repelling layer. The surfactant is effective to prevent the spread of the oil-based magnetic fluid into interior mechanisms of the sealed apparatus, which may typically require a high degree of cleanliness.

DETAILED DESCRIPTION An object, therefore, of the present invention is to provide a magnetic fluid seal apparatus that is free from all of the aforementioned defects of the prior art.
