The impeller vanes are positioned to be in the path of travel of oil flung off of a bull gear which rotates in an oil pan extending into an oil bath contained in the housing. The impeller is rotated by the impact of the oil against its vanes.

In another embodiment, the rotating impeller drives fans disposed outside of the housing at both ends of the impeller shaft.
