  • Patent number: 10035164
    Abstract: A spraying apparatus comprising a plurality of spray nozzle assemblies mounted along a liquid supply boom. The spray nozzle assemblies each include a one piece spray nozzle and retention cap (20) having an upstream cap section (21) and a downstream nozzle section (22) integral with the cap section. The cap section (21) is formed with internal camming and locking grooves (25) for drawing the cap section into mounted position on a liquid inlet stem (12) as an incident to rotation of the cap, and the nozzle section (22) has a liquid inlet passage (41) communicating with the inlet stem (12) for directing a discharging liquid spray. A pre-orifice insert (60) is mounted within the spray nozzle and retention cap (20) which has a smaller diameter nozzling passage section, and an intermediate section (24) of the one piece spray nozzle and retention cap (20) is formed with air passageways communicating between the pre-orifice liquid flow passage and outside ambient air.

  • Patent number: 7380732
    Abstract: A spray tip for discharging a controlled liquid spray distribution is provided. The spray tip includes a spray tip body having an inlet end for connection to a pressurized liquid supply. The spray tip body includes a first fluid chamber having a first longitudinal axis and a second fluid chamber in fluid communication with the first fluid chamber and having a second longitudinal axis that extends transversely relative to the first longitudinal axis. A pair of discharge orifices are formed in the spray tip body. Each discharge orifice has a downstream side with a deflector surface for directing liquid discharging from the chamber. Each discharge orifice intersects the second fluid chamber adjacent a respective end thereof so as to define a pocket extending downstream of the deflector surface.

  • Patent number: 6866211
    Abstract: A spray nozzle for directing a wide lateral spray curtain with substantially uniform liquid distribution throughout the length of the spray curtain is provided. The nozzle includes a nozzle body defining an elongated internal flow passage. The nozzle body includes an inlet end for connection to a pressurized liquid supply, a downstream end wall and a side wall. A discharge orifice is provided in the side wall of the nozzle body between the inlet end and the downstream end wall. The discharge orifice communicates with the internal flow passage of the nozzle body. The discharge orifice has a generally inverted teardrop configuration comprising a relatively larger area upper portion and a relatively smaller area lower portion arranged below the upper portion.
