Abstract
A rotating spray nozzle assembly 10, for use with high pressure water, has a hollow distribution arm 12 radially attached to a hollow rotation shaft 14. Attached to distribution arm 12 are a plurality of spray nozzles 13. Pressurized water from water chamber 16 sequentially activates, via inlet rotor 21, bevelled and pistons 24 which in turn drive cylindrical wedge cam 31. Cylindrical wedge cam 31 circumscribes and is attached to hollow rotating shaft 14. The hollow rotating shaft 14 derives its rotation from the action of bevelled end pistons 24.
