Abstract
A rotary sprinkler includes a housing supporting a nozzle and a nozzle tube, the nozzle tube located axially adjacent an orifice of the nozzle with an axial gap therebetween. A water-deflection plate assembly is carried by the nozzle tube for rotation relative to the nozzle tube. The housing is formed with an exterior substantially annular funnel surrounding the nozzle and forming a collection trough for collection of excess water, and the housing formed with one or more apertures directing excess water in the collection trough to an internal area surrounding the orifice to be aspirated through the gap into a stream of water emitted from the nozzle orifice and through the nozzle tube such that the excess water is distributed by the water-deflection plate along with water emitted from the nozzle orifice.
