ABSTRACT:
A pop-up rotary sprinkler includes a sprinkler body, a rotatable distributor and nozzle assembly mounted in the sprinkler body for movement between inoperative retracted and operative extended positions in response to fluid pressure within the sprinkler body. The rotatable distributor has a plurality of water distribution grooves and is supported at an upper end portion of a shaft, while the nozzle assembly surrounds a lower end portion of the shaft. The nozzle assembly includes a discharge orifice having a peripheral surface at least a part of which is defined by a peripheral surface of the shaft, and a deflector is mounted on the shaft downstream of the discharge orifice and upstream of the distributing grooves, and is adapted to direct water emanating from the discharge orifice onto the distributing grooves so as to avoid direct impingement on a seal located at the distributor-shaft interface.
