PRESSURE REGULATOR FOR CONTAINER FOR LIQUID DELIVERY Russian patent published in 2009 - IPC B65D83/66 

FIELD: mechanical engineering.

SUBSTANCE: invention relates to device for dispersion. Pressure regulator for container contains: the first cylinder with open and closed end, provided for filling by compressed gas with specified excessive pressure, piston with sealing annular, relocatable inside the first cylinder, the second cylinder with closed end and opened end, provided for filling by compressed gas under pressure, exceeding excessive pressure. The second cylinder envelops the first cylinder, forming annular channel. Opened end of the second cylinder joins open end of the first cylinder. Channel leads outside from within the second cylinder and past external wall of the first cylinder. For opening and closing of channel it is a valve. Piston contains rod for opening and closing of a valve. Opened end of the first cylinder is outfitted by axial opening, such, that piston with sealing annular in position at standard pressure is introduced into the first cylinder and closes opening end. Rod is outfitted by lock member, which closes valve in top position of piston, length of piston specifies piston stroke between position at standard pressure and closed position of valve. Piston stroke jointly to internal volume of piston space defines in closed position of valve specified excessive pressure.

EFFECT: invention provides for creation of pressure in regulator simultaneously with filling.
