A turret-type spray nozzle assembly having a rotatable turret which carries a plurality of spray nozzles and which is rotatable on the nozzle body for locating a selected one of the turret nozzles in an operative spray position. The spray nozzle assembly further includes an auxiliary spray nozzle adapted for directing a higher volume liquid spray than any one of the turret spray nozzles. The spray nozzle assembly includes a body which defines a more direct liquid flow passage, with fewer turns and lesser pressure losses, to the auxiliary nozzle than to a turret spray nozzle. An adaptor also is disclosed for convenient field conversion of a conventional turret spray nozzle into a nozzle assembly according to the invention.

The spray nozzle assembly of claim 1 in which said auxiliary nozzle liquid flow passage is shorter in length than said turret nozzle liquid flow passage.3. The spray nozzle assembly of claim 1 in which said turret nozzle liquid flow passage effects lesser pressure losses on liquid traveling between said liquid inlet and said auxiliary nozzle than the pressure losses incurred by liquid traveling between said liquid inlet and a turret nozzle located at said operative position.4. The spray nozzle assembly of claim 1 in which each of said turret nozzles is a quick disconnect nozzle adapted for removable mounting on said turret, and said auxiliary nozzle is a quick disconnect nozzle adapted for removable mounting on said auxiliary mounting section.5. The spray nozzle assembly of claim 1 in which said auxiliary nozzle mounting section and said auxiliary nozzle are disposed below said liquid inlet and said turret mounting section is located below and laterally to one side of said liquid inlet.6. The spray nozzle assembly of claim 1 in which said turret includes a generally cylindrical hub mountable on said turret mounting section and a plurality of radial stems each extending radially outwardly of said hub and having a central liquid flow passage, said turret spray nozzles each being removably mounted on one of said stems, and said turret liquid flow passage communicates from said liquid inlet, axially into said turret mounting section and to the central passage of the mounting stem of a turret nozzle located in said operative position.7. The spray nozzle assembly of claim 6 in which said turret nozzle liquid flow passage makes a right angle bend between said liquid inlet and the portion of the turret nozzle flow passage thereof that communicates axially into said turret section, and said auxiliary mounting stem and auxiliary nozzle are disposed directly below said liquid inlet.8. The spray nozzle assembly of claim 1 in which said turret nozzle liquid flow passage includes an inlet passage communicating with said inlet, a turret mounting section passage in fluid communication with and disposed at a right angle to said inlet passage, and a turret nozzle mounting section passage communicating at a right angle to said turret mounting section passage, and said auxiliary nozzle liquid flow passage includes an inlet passage communicating with said liquid inlet, and an auxiliary nozzle mounting section passage communicating with said inlet passage.9.

The spray nozzle assembly of claim 1 in which said auxiliary nozzle liquid flow passage is designed to enable spraying of at least about twice the liquid volume the turret nozzle liquid flow passage enables any one of the turret nozzles located in said operative position to spray.13. The spray nozzle assembly of claim 1 in which said turret nozzle liquid flow passage includes an inlet passage communicating with said liquid inlet, a check valve passage communicating at a right angle to said inlet passage, a turret mounting section passage communicating at a right angle with said check valve passage, and a turret nozzle mounting section passage communicating at a right angle to said turret mounting section passage, and said auxiliary nozzle liquid flow passage includes said inlet passage communicating with said liquid inlet, said check valve passage communicating at a right angle to said inlet passage, and an auxiliary nozzle mounting section passage communicating at a right angle to said check valve passage.14. The spray nozzle assembly of claim 1 in which said turret includes a hub rotatably mounted on said turret mounting section, said turret nozzle liquid flow passage includes a passage communicating axially into said hub and a right angle exit passage communicating radially through said turret mounting section, and said turret having a plurality of circumferentially spaced radially extending turret nozzle mounting stems, and said turret nozzle mounting stems each having a passageway communicating between a turret spray nozzle mounted on the stem and said turret mounting section exit aperture when the turret nozzle is located in said operative spraying position.15. The spray nozzle assembly of claim 1 in which said nozzle body includes a liquid inlet section which defines an inlet passage communicating with said liquid inlet, a check valve hub section disposed below said liquid inlet section, and said turret mounting section being disposed laterally to one side of said check valve hub section, and said auxiliary nozzle mounting section being located below said check valve hub section.16. The spray nozzle assembly of claim 1 in which said turret mounting section and auxiliary nozzle mounting sections are integrally formed parts of said nozzle body.17. The spray nozzle assembly of claim 1 in which said nozzle body turret mounting section is disposed in perpendicular relation to said nozzle body auxiliary nozzle mounting section.18. A spray nozzle assembly comprising a nozzle body having a liquid inlet, a turret mounting section, and an auxiliary nozzle mounting section, a turret rotatably mounted on said turret mounting section and having a plurality of turret nozzles, said turret being rotatable on said turret mounting section to locate any selected one of said turret nozzles in an operative spraying position, an auxiliary nozzle mounted on said body auxiliary nozzle mounting section, said body defining a turret nozzle liquid flow passage communicating between said liquid inlet and a turret nozzle located in said operative position for supplying liquid to be sprayed by said located turret nozzle, said body defining an auxiliary nozzle liquid flow passage, different from said turret nozzle liquid flow passage, communicating between said liquid inlet and said auxiliary nozzle for supplying liquid to be sprayed by said auxiliary nozzle, and said auxiliary nozzle liquid flow passage making fewer turns and being shorter in length than said turret nozzle liquid flow passage. 19.
