Abstract
A clearance-type seal for use in rotary fluid handling machinery for preventing lubricant from leaking into working fluid by flowing by capillary action along a fixed surface wherein a coating which is not wetted by the lubricant is placed on the fixed surface of the machinery such that any lubricant which may flow onto the coating is caused to bead up and is thus easily swept away by flow of seal gas.
