Abstract: The invention is the complex technical solution covering the method for the continuous liquid jet formation and ejection, the generator for ejection such jet and the special shutter for blocking the jet in the generator and designed for use in the method. A distinctive feature is the switching between the two jets, which causes neither a stop of the liquid flow in the generator nor fluctuations in the liquid pressure in it, when one jet is drained to the source of liquid. The invention is intended for organizing the process of metered ejection of free continuous liquid jets, for example, liquid chemical treatment agents, without loss of liquid outside its trajectory.

Abstract: A sprayer nozzle assembly includes a control valve configured to control a flow rate of agricultural product according to a duty cycle having valve open and valve closed positions. The assembly includes a sprayer tip having a tip orifice for spraying the agricultural product. A throttled interface duct interconnects the control valve and the sprayer tip. The throttled interface duct includes an interface duct profile. The interface duct profile is configured to decrease a flow characteristic of the agricultural product while the control valve is in the valve closed position.

Abstract: A spray nozzle has a nozzle portion at an outlet or downstream end that includes a nozzle body defining an opening therethrough, and a movable stem or pintle at least partially within the opening of the nozzle body. The stem and nozzle body define a gap therebetween to define a fluid passageway for fluid in the nozzle to flow through the nozzle portion and out of the nozzle throughout a range of relative movement between the stem and the nozzle body. The relative movement and the size of the gap may be controllable independently of fluid pressure of fluid within the nozzle. The nozzle body and the stem may define geometries so that the flow area between the stem and the nozzle body does not increase, and may decrease, in the downstream direction. The axis of the spray may be at an angle to the nozzle.

Abstract: A spray nozzle includes a nozzle housing formed of a first material and a nozzle tip having a spray opening formed of a second material. The second material has a greater resiliency than the first material. The nozzle tip has a spray opening that is closed inhibiting air entry into the nozzle housing in a first configuration and opened in a second configuration. The spray nozzle changes from the first configuration to the second configuration by an increase of pressure of the liquid in the spray nozzle operable to spray liquid out of the opened spray opening in the second configuration. A method of using the spray nozzle is also provided.
