ABSTRACT:
A pop-up, rotating stream sprinkler device includes an outer housing having a first longitudinal axis, an inlet end adapted for connection to a source of liquid under pressure, a first inner housing telescopically mounted within the outer housing for movement between retracted and extended positions, and having a second longitudinal axis coincident with the first longitudinal axis, and an outlet end provided with a first arcuate slot adapted to discharge a stream of liquid under pressure. A non-rotatable shaft supports at one end thereof a substantially hollow distributor for rotation thereon downstream of the outlet. The other end of the shaft is fixedly mounted in the first inner housing, and the hollow distributor includes an interior chamber enclosing a brake assembly for retarding the rotation of the distributor. A nozzle disk is removably and rotatably secured to the first inner housing and provided with at least one discharge orifice, so that the nozzle is rotatable to align any part of the at least one discharge orifice with the arcuate slot.
