Abstract
A fluid coupling includes inner and outer members capable of rotating relative to each other. The inner member includes an inner member interior wall centered about a coupling axis, and a first inner member seal wall centered about the coupling axis and spaced radially outwardly from the inner member interior wall to define a first gap between the inner member interior wall and the first inner member seal wall. The outer member has an outer member exterior wall centered about the coupling axis and surrounding the first inner member seal wall, and a first outer member seal wall centered about the coupling axis and spaced radially inwardly from the outer member exterior wall. The first outer member seal wall is disposed in the first gap to form a labyrinthine seal passage between the inner and outer members.
