This equipment is of the type comprising a spray gun provided with a hydrostatic atomizing nozzle delivering a flat jet of liquid in combination with a pair of orifices disposed on either side of the nozzle and symmetrically in relation to the flat jet of liquid so as to deliver air jets in a plane perpendicular to that of the flat jet of liquid. The front surface of the nozzle is frustoconical and the two orifices are adapted to direct the air jets against said frustoconical surface and thus create two fan-shaped sheets of compressed air on either side of the flat jet of liquid also of fan-like configuration, said two fan-shaped sheets of compressed air being somewhat wider than the jet of liquid and meeting together at their edges while clamping said liquid jet. The equipment further comprises means for varying the pressure of the paint or other product from 5 to 30 bars (72.5 to 435 lbf) and the air jet pressure from 1 to 4 bars (14.5 to 58 lbf). |
