Abstract
A nutating sprinkler assembly includes a sprinkler body having one end adapted to be coupled to a water supply conduit and an opposite end supporting a nozzle. At least one arm extends from the sprinkler body for supporting a removable cap assembly downstream of the nozzle. The cap assembly supports a gimbal bearing that, in turn, supports a rotor plate with off-center grooves for distributing a stream exiting the nozzle and impinging upon the grooves. A shaft has one end supporting the rotor plate for rotation about a center axis of the rotor plate, and an opposite end supported within the gimbal bearing.
