摘要：A vehicle mounted spray system includes a variable orifice spray nozzle (21-24)and control apparatus to correlate the delivery for pressirized fluid spray product to thenozzle in a selected ratio to the ground speed of the vehicle. The spray nozzle includes acircular orifice (61) with a conical valve seat (62) and a fluidic pressure element mountedfor reciprocation therein. The taper of the valve element (49) is less than the taper of thevalve seat and the apex of the needle valve protrudes beyond the orifices to create asolid stream flow of the spray product. The solid stream spray is projected onto thesurface traveled in a direction opposite the direction for travel and at an angle therewith.The nozzle velocity of the spray product is equal to or greater than the vehicle velocity.
