Abstract:
A spray nozzle assembly comprising a nozzle body and a separate nozzle body insert adapted for removable snap action engagement with the body. The nozzle body insert defines a liquid flow passage that includes an inlet section for communicating with a liquid inlet, a metering orifice for accelerating the liquid flow stream, and a downstream expansion section. The body insert further includes a venturi passage communicating with the expansion section for drawing ambient air into the liquid flow stream for stabilizing the liquid prior to discharge from the nozzle. In the illustrated embodiment, the expansion chamber communicates with a transverse passage of the nozzle body, which in turn communicates with a laterally oriented discharge orifice.

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.

Abstract:
A liquid spray boom having a plurality of spray nozzles and a flow monitoring system for monitoring the liquid flow to each of the spray nozzles. The spray nozzles each have a respective flow metering passage through which liquid to the nozzle passes a magnetic turbine in the metering passage rotatable as an incident to and in relation to liquid directed through the flow metering passage for generating changing magnetic fields, a hall effect sensor associated with each magnetic turbine for sensing the changing magnetic fields, and a control module for receiving signals from the sensor for monitoring the liquid flow to each spray nozzle and providing an alert indication in the event that the flow fails to meet predetermined requirements.
