Abstract

The disclosure concerns a pumping apparatus for working fluid, in a hydrodynamic coupling, or the like. Working fluid is stored in a sump and is to be lifted by a spinning disc to an elevated container from which the working fluid is then directed back into the spinning disc. The periphery of the spinning disc picks up the working fluid from the sump and carries it around to spary it up toward a deflector at the top of the housing which deflects the fluid into the container. A groove-like duct encloses the lower quarter of the disc for directing the fluid back toward the surface of the disc. The disc has a trapezoidal cross-section peripheral groove for further carrying the fluid beyond the top exit of the duct so that the fluid may be thrown toward the deflector at the top of the housing.
