PCT No. PCT/GB92/00757 Sec. 371 Date Mar. 14, 1994 Sec. 102(e) Date Mar. 14, 1994 PCT Filed Apr. 24, 1992 PCT Pub. No. WO92/19385 PCT Pub. Date Nov. 12, 1992.A liquid spray device particularly for agricultural and horticultural apparatuses is disclosed. A nozzle is provided through which liquid is emitted in a sheet, preferably a conical sheet. A source of heated air or gas, preferably a burner, is directed to interact with the liquid and is drawn through the liquid curtain to initiate the breakup into droplets of a liquid sheet, thus regulating the droplet size to minimize wastage of expensive agrochemicals or other materials. A shroud is provided to protect the gas in the vicinity of the nozzle from drafts. A thermal sensor is located in the shroud to interrupt the fuel supply to the flame or heated gas if the spray is interrupted. |
