Abstract
A sprinkler unit for distributing water from a source over an area of terrain comprises a tubular housing having an inlet connected by a passage to an outlet, a distributor head mounted at the outlet for rotation about an axis for distribution of water via a nozzle, a turbine wheel disposed in the housing passage and operatively connected for driving the distributor head, and a turbine stator assembly having a passage including a throttling device for controllably directing a first portion of water to the turbine wheel, and a pressure responsive valve for controllably diverting a second portion of the water around the turbine wheel in proportion to the pressure thereof for maintaining the speed of the turbine substantially constant.
