VALVE TYPE BARRIERLESS LOW PRESSURE DISCHARGE VESSEL FOR STORAGE AND DISCHARGE OF LIQUIDS BY COMPRESSED OR LIQUEFIED GAS AND METHOD OF DISCHARGE OF LIQUID MATERIAL IN AEROSOL FLOW

摘要

FIELD: proposed aerosol low-pressure discharge vessel differs from high pressure aerosol discharge vessels. SUBSTANCE: usually cylindrical container has thin walls, similar to those of vessels for carbonated drinks, which can be bent by fingers but whose shape is maintained by internal pressure of gases. Liquid components and propellant are mixed in vessel. Distributing valve in top of vessel distributes liquid components and propellant in controlled manner. Valve can be provided with additional drilled hole-evaporating passage-between propellant in head space of vessel and valve chamber to discharge additional amount of gas for breaking the liquid and discharging it through nozzle. Gas pressure in vessel is coordinated with thickness of wall and bottom to render vessel a sufficient resistance to deformation and breakage at higher temperature. But thickness of side wall is sufficiently little to permit crumpling an empty vessel by hand. EFFECT: enlarged operating capabilities. 1 dwg
