The way restylene the fluid through the device is as follows.
When driving the tractor along the grape trellis starts pump 2, which feeds the liquid from the tank 1 to the nozzles 3. At the same time from the FIRST through the actuator 10 is driven fan working body 10 and through the adjustable orifice 5 input channel 6 is sucked air flow. Changing the diameter of the hole 5, to regulate the pressure of the air flow, thereby to regulate the flow of the liquid and the drug, and hence the flow rate of the working solution. When the air flow enters the space in front of the fan working body 10, there is a sharp turbulization of the flow and the simultaneous interaction of it with the liquid supplied from the nozzles 3. As a result of this interaction produces a well-mixed air-liquid mixture, which then hits the fan working body, crushed into fine droplets and through output channel 8 and the nozzle 9 is sprayed.
