METHOD AND DEVICE FOR CARRYING OUT VACUUM SPRAYING Russian patent published in 1995 - IPC

FIELD: mechanical engineering. SUBSTANCE: method involves creating additional vacuum zone acting upon the main one with oppositely directed force vector creating the common vacuum of the doubled flow rarefaction. The common vacuums of the flows influence each other with oppositely directed force vectors resulting in creating the united vacuum enabling the ejected ingredient to be supplied into the united vacuum zone. The device has branch pipe for supplying the ingredient to be injected and intermediate cylinders. The branch pipe communicates with the middle part of the vacuum line. Each of the intermediate cylinders is placed in the corresponding vacuum head between the external and internal cylinders and has perforations in the conic nozzle zone. EFFECT: enhanced effectiveness in spraying liquids. 2 cl, 1 dwg
