Abstract
A rotary spray washer for heavy duty applications. Each spray device in the system comprises a rotary coupling and two sets of radially extending spray arms. Each set of arms has nozzles at the distal ends to direct water generally toward a target area but angled enough to produce a rotation-producing reaction torque. One set of arms is longer than the other whereby the shorter arms produce a reaction torque which limits the overall speed of rotation without the need for a friction brake or fluid pump brake.
