Abstract
A miniature sprinkler has a fixed vertically extending nozzle in communication with a supply pipe and includes a flow diverter having an axially extending inlet in register with the nozzle outlet. The diverter is rotatably mounted by an axially extending shaft loosely retained in a bushing at the top of the nozzle. The diverter inlcudes a the side outlet and an open arcuate channel between the inlet and side outlet from which the water is emitted in the form of a jet. The drive apparatus includes at least one blade affixed adjacent the periphery of the flow diverter and at least partially aligned with the diverter outlet so that at least part of the flow from the diverter outlet impinges on the blade to cause the rotation of the diverter. The blade is being shaped such as to change the direction of the flow of water impinging thereupon. The diverter is axially movable relative to the nozzle to close the outlets and the nozzle in the absence of water flowing through the nozzle.
