BARRIERLESS-TYPE VESSEL FOR STORAGE AND DISCHARGE OF LIQUID MATERIAL BY MEANS OF COMPRESSED AND/OR LIQUEFIED GAS AND METHOD OF DISCHARGE OF LIQUID MATERIAL IN AEROSOL FLOW Russian patent published in 1997 - IPC

FIELD: aerosol-type spraying vessels for spraying liquefied or liquid materials. SUBSTANCE: low-pressure aerosol discharge vessel differs from existing high-pressure discharge vessels. Standard cylindrical vessels have thin walls which may be bent by fingers but their form is maintained by internal pressure of gas. Liquid components which are to be discharge and propellant gas are mixed in vessel. Distributing valve fitted at the top of vessel spreads liquid components and propellant by controllable method. Valve may be provided with additional drilled hole - evaporating passage - between gaseous propellant in head space of vessel and chamber of valve for discharge of additional amount of gas for crushing the liquid and discharging it from nozzle. Pressure of gas contained in vessel is coordinated with thickness of wall and bottom of vessel in such way that vessel possesses adequate resistance to deformation and break at high temperature. Nevertheless thickness of side wall is small and empty vessel may be easily crumpled by hand force. EFFECT: enhanced efficiency. 23 cl, 4 dwg
