  • Spray nozzle assembly with auxiliary high volume spray nozzle
    Patent number: 6749134
    Abstract: 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.
