ABSTRACT:
An eyeball fitting 10 for directing return water into a swimming pool has an eyeball 20 with a smooth and even inside surface 25 curving continuously from an entrance opening 26 to a discharge opening 21 having a sharp edge 22. The curvature of inside surface 25 has a radius that gradually increases as inside surface 25 gradually diminishes in cross-sectional area proceeding from larger diameter entrance opening 26 to smaller diameter discharge edge 22. Fitting 10 includes a seat 30 having a spherical recess 33 to receive a spherical outside surface 24 of eyeball 20, and seat 30 has an internal surface 35 continuously curving at a gradually increasing radius of curvature proceeding from an entrance side toward the spherical recess 33.
