Patent Images
1. A sprinkler, comprising:
- a gear drive mounted inside a gear box and including an upper input stage and a lower output stage;
an inverted frusto-conical rotary distributor head coupled to the output stage of the gear drive, the rotary distributor head having a plurality of circumferentially spaced radially extending recesses;
a turbine located between the rotary distributor head and the gear drive and coupled to the input stage of the gear drive;
a housing that defines a flow path between the gear box and the housing, the flow path leading to the turbine;
a nozzle base that supports the gear box and includes a threaded segment that can be screwed to an upper threaded segment of a riser; and
a nozzle plate supported by the nozzle base adjacent the rotary distributor head and configured to direct water into the recesses so that the recesses can simultaneously eject a plurality of outwardly directed streams of water.
