A nozzle assembly includes a plastic, one-piece flood tip that attaches directly over the bayonet connector of a nozzle body. The nozzle body is of the diaphragm type for reduced weight, cost and complexity but modified to increase flow capacity. In one embodiment, a 90-degree bayonet is provided on the nozzle body turret, and other bayonet selections are also available on the turret for flat fan spray patterns. In a second embodiment, a conventional radially extending bayonet pattern is provided, and the flood tip itself is fabricated with a 90-degree turn. The plumbing system utilized for high spray rate applications with the flood tip is the same as for lower rate spraying using a different tip mounted on other bayonet connector on the turret.

1. A nozzle assembly for a sprayer comprising:a body in fluid communication with a single supply line providing a source of pressurized spray fluid to the body at a rate up to about 10 gallons per minute;a turret connected to the body for rotation about a turret axis, the turret including at least first and second spray tip-receiving connectors for receiving spray tips of differing spray tip capacities in a range from about 0.1 gallons to 10 gallons per minute; anda high spray capacity flood tip nozzle matingly received by the first connector, wherein the turret is rotatable for selecting spray fluid flow through the high spray capacity flood tip nozzle, the flood tip nozzle having a spray capacity substantially greater than 2 gallons per minute, and lower capacity nozzle received by the second connector having a spray capacity less than 2 gallons per minute, wherein the turret is rotatable for selecting spray fluid flow through the lower capacity nozzle and the first and second connectors extend radially from the turret. 2. A nozzle assembly for a sprayer comprising:a body adapted for connection to a source of pressurized spray fluid;a turret connected to the body for rotation about a turret axis, the turret including at least first and second spray tip-receiving connectors for receiving spray tips of differing spray tip capacities;a high spray capacity flood tip nozzle matingly received by the first connector, wherein the turret is rotatable for selecting spray fluid flow through the high spray capacity flood tip nozzle; andwherein first connector opens outwardly in a radial direction, and the flood tip nozzle includes a passage angled with respect to the radial direction to direct spray fluid generally in the direction of the turret axis. 3. The nozzle assembly as set forth in claim 1 wherein the flood tip nozzle includes a passageway with an outlet port opening generally horizontally, and wherein the first connector opens in a direction generally parallel to the turret axis and into the passageway, and wherein the flood tip nozzle includes a deflector intercepting fluid from the outlet port and directing the fluid downwardly. 4. The nozzle assembly as set forth in claim 1 wherein the flood tip nozzle is of single one-piece, non-metallic construction. 5. The nozzle assembly as set forth in claim 1 including a first tip of first spray capacity in the range of 0.1 to 2.0 gallons per minute and wherein the high capacity flood tip nozzle includes a tip with capacity in the range of 2.0 to 10.0 gallons per minute. 6. The nozzle assembly as set forth in claim 1 wherein the body includes a diaphragm valve located between the source and the connectors for selectively controlling flow to the connectors, the diaphragm valve responsive to spray fluid pressure of the source for interrupting fluid flow to the flood tip nozzle when the pressure drops below a shut-off value. 7. The nozzle assembly as set forth in claim 1 wherein the first connector comprises a bayonet connector extending radially from the turret, and the flood tip nozzle comprises a one-piece non-metallic structure received by the bayonet connector independently of additional connecting structure. 8. A nozzle assembly for a sprayer comprising:a body adapted for connection to a source of pressurized spray fluid;a turret connected to the body for rotation about a turret axis, the turret including at least first and second spray tip-receiving connectors for receiving spray tips of differing spray tip capacities;a high spray capacity flood tip nozzle matingly received by the first connector, wherein the turret is rotatable for selecting spray fluid flow through the high spray capacity flood tip nozzle; andwherein the flood tip nozzle includes a passageway having an inlet component extending generally radially and an outlet component angled from the inlet component in the direction of the turret axis, and a deflector directing flow from the outlet component in the radial dire ction. 9. A nozzle body for a flood tip nozzle assembly of an agricultural sprayer having a single fluid line, comprising:a body portion including an inlet for connection to a source of spray fluid under pressure;a turret connected to the body portion for rotation about a turret axis, the turret including a plurality of spray tip-receiving connectors for receiving spray tips of differing spray tip capacities, including a flood tip-receiving connector having a capacity in the range of 2.0 to 10.0 gallons per minute, wherein the turret is rotatable for selecting spray fluid flow through one of the connectors; andwherein the body portion includes a diaphragm type valve located between the inlet and the turret and responsive to the pressure of the spray fluid for stopping the fluid flow to the connectors when fluid pressure drops below a minimum pressure, the valve having a throughput capacity of greater than 2.0 gallons per minute, the single fluid line providing substantially all the fluid flow to a flood tip and control of the flow to the flood tip. 10. The nozzle body as set forth in claim 9 wherein the flood-tip receiving connector comprises a bayonet connector. 11. A nozzle body for a flood tip nozzle assembly of an agricultural sprayer, comprising:a body portion including an inlet for connection to a source of spray fluid under pressure;a turret connected to the body portion for rotation about a turret axis, the turret including a plurality of spray tip-receiving connectors for receiving spray tips of differing spray tip capacities, including a flood tip-receiving connector having a capacity in the range of 2.0 to 10.0 gallons per minute, wherein the turret is rotatable for selecting spray fluid flow through one of the connectors; andwherein the body portion includes a diaphragm type valve located between the inlet and the turret and responsive to the pressure of the spray fluid for stopping flow to the connectors when fluid pressure drops below a minimum pressure, the valve having a throughput capacity of greater than 2.0 gallons per minute, so that only a single fluid line is required to supply and control fluid flow to a flood tip; andwherein the flood-tip receiving connector comprises a connecting portion angled from a radial direction with respect to the turret. 12. A flood tip nozzle for a spray nozzle body of an agricultural sprayer having a connecting portion with an upright axis for directing pressurized fluid downwardly towards material to be sprayed, the nozzle comprising:an inlet area adapted for mating connection with the connecting portion and having a first conduit portion extending generally in the direction of the upright axis and an outlet portion having a second conduit portion extending at an angle to the first conduit portion and providing a generally horizontal flow of the pressurized fluid outwardly from the second conduit portion;a deflector located in the path of the generally horizontal flow to direct the pressurized fluid towards the material to be sprayed; andwherein the nozzle has a capacity in the range of 2.0 to 10.0 gallons per minute. 13. The nozzle as set forth in claim 12 wherein the inlet area includes a bayonet connection. 14. The nozzle as set forth in claim 13 wherein the inlet area includes projecting ears facilitating mounting of the nozzle on the connecting portion.
