KOCHETOV'S AIR-BLAST ATOMISER Russian patent published in 2014 - IPC A62C31/02 

FIELD: machine building.

SUBSTANCE: in air blast atomiser, comprising the housing with supply of atomised fluid and gas, the jet guiding device and atomiser, the housing is made in the form of inverted barrel, in the bottom of which the thread hole for fastening the central cylindrical insert (axi-symmetric to the housing) with the central axial passage of jet guiding device for supply of atomised fluid is made, and in a lateral surface of the housing, perpendicularly its axis, at least one hole for supply of air (gas) under pressure is made, which is coupled with the ring-type camera formed by external surface of the central cylindrical insert and internal surface of the housing, and to the internal lateral surface of the housing, in its bottom, the cylindrical bush of jet guide device for gas supply under pressure to the atomiser is fastened using annular gap, formed by an external surface of the central cylindrical insert and internal surface of the bush, while the annular gap is connected to the ring-type camera, and to the central cylindrical insert the atomiser made as a conical bell is fastened coaxially, in bottom part of which, perpendicularly to its axis, the face round plate with at least three conical throttle holes with the cone-apex angle laying within a range from 45° up to 90°, is rigidly fastened, while on the lateral surface of the bell two rows of cylindrical throttle holes, with axes laying in plains, perpendicular to the bell axis are made, at least, and in each row at least three holes are made.

EFFECT: higher efficiency of spraying.
