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.
A pop-up rotary sprinkler comprising a sprinkler body, a rotatable distributor and a non-rotatable nozzle assembly mounted in said sprinkler body for movement relative to said sprinkler body between inoperative retracted and operative extended positions in response to fluid pressure within said sprinkler body, said assembly including a rotatable distributor supported at an upper end portion of a shaft and a non-rotatable nozzle assembly surrounding a lower end portion of the shaft in axially spaced relationship to said rotatable distributor, with said nozzle assembly, arranged to discharge a stream to atmosphere;
In a rotary sprinkler having a sprinkler body, a non-rotatable nozzle assembly arranged to discharge a stream to atmosphere, and a rotatable distributor assembly, wherein the rotatable distributor assembly and the non-rotatable nozzle assembly and the non-rotatable nozzle assembly are axially fixed in spaced relationship with respect to each other by means of a non-rotatable shaft, and wherein said distributor assembly includes stream distribution surfaces arranged to receive the stream downstream from said nozzle assembly, the improvement comprising a discharge orifice in said non-rotatable nozzle assembly at least partially defined by said non-rotatable shaft, and a deflector on said non-rotatable shaft between said discharge orifice and said rotatable distributor assembly for deflecting the stream emanating from said discharge orifice away from an interface of said non-rotatable shaft and said rotatable distributor and onto said stream distribution surfaces.
A rotary sprinkler including a sprinkler body having an outlet end, a discharge nozzle assembly located within said outlet end and including a discharge orifice;
A pop-up rotary sprinkler comprising a sprinkler body, a rotatable distributor and nozzle assembly mounted in said sprinkler body for movement between inoperative retracted and operative extended positions in response to fluid pressure within said sprinkler body, said assembly including a rotatable distributor supported at an upper end portion of a stationary shaft and a nozzle assembly surrounding a lower end portion of the shaft, said distributor having a plurality of water distributing grooves, and said nozzle assembly including a discharge orifice having a peripheral surface at least a part of which is defined by a peripheral surface of said shaft;
