Automatic antidrip valve for attachment to the nozzle supports of mist and atomizing machines for pest-control and weed-control treatments for farming and municipal uses

摘要

Automatic antidrip valve for attachment to the nozzle supports of fan-type mist and atomizing machines for orchard use, and of irrigating bars, used for pest- control and weed-control treatments for farming and municipal uses, characterized in that this antidrip valve is of the plunger type, instead of ordinary ball membrane antidrip valves which are inefficient, unreliable, large and/or expensive - characterized in that this valve can be wholly enclosed inside the rod of the nozzle support itself. - characterized in that its fitting inside the rod almost entirely eliminates the bulk which, in present-day valves, creates harmful aerodynamic turbulence in fan- type atomizing machines and interferes with irrigating bars. The object of the invention is a substantial improvement to the nozzle supports of the abovementioned pest-control machines through: A - elimination of turbulence and interference. B - efficient antidrip function. C - reduction of construction and maintenance costs. D - greater efficiency, reliability and durability. IMAGE
