Abstract
A rotary seal has a floating seal face (21), in sealing relationship with a stationary seal face (22) and a fluid collection cavity (52, 34) adjacent the seal faces. The seal includes means (15) for introducing a lubricant into the vicinity of the cavity and means (19) for promoting the coalescence of the lubricant so that the lubricant accumulates in the cavity and lubricates the seal faces.
