Abstract
A plurality of circumferentially spaced apart oil scoops are designed to capture oil being slung from an inner shaft across an annulus to an outer shaft which rotates in a direction opposite to the inner shaft. The scoops rotate with and are a part of the outer shaft assembly. The scoops, in one embodiment, are defined by opposed spaced apart wall surfaces oriented substantially parallel to the relative velocity vector of the jets of oil as they travel outwardly from the inner shaft across the annulus. Splashing of the oil as it is picked up by the scoops is minimized by this invention.
