Abstract
A labyrinth seal ring designed to function properly regardless of its rotational orientation relative to a horizontal shaft to be sealed. The novel seal ring bore is formed with a series of lands and grooves, with a plurality of axially extending drainage grooves cut across the axially inner lands to allow fluid to drain back into the associated housing interior. The pattern of the drainage grooves varies from land to land so that nowhere is there a direct flow path across more than two lands. The new ring will most likely be used in conjunction with a bearing isolator seal, but it may be used alone in some applications.
