PRESSURE CONTROL DEVICE FOR VESSEL USED FOR PRESSURE ATOMIZING OF LIQUIDS Russian patent published in 2006 - IPC B65D83/14 

FIELD: mechanical engineering; pressure atomizing devices.

SUBSTANCE: invention relates to device providing control of pressure in vessel used for pressure atomizing liquids and it can be used in aerosol fuel bottles and atomized liquids. Proposed device contains bottle with liquid medium under pressure. Bottle is sealed by unit of cap provided with expanding chamber and pass for flow to let liquid medium get from bottle into inner part of atomizer. Shutoff in cap unit provides opening and closing of flow passage. Drive in cap unit is made for setting shutoff in operation. Drive operates in response to expansion of expanding chamber and check valve connecting expanding chamber with inner part of atomizer through hole in cap unit. Valve is provided with elastic sealing of chamber in expanding chamber passing through hole and limited by wall of chamber to let liquid medium pass through hole after seal and fill chamber to preset pressure differential which is lower than pressure in atomizer. Expanding of chamber in atomizer takes place when pressure in atomizer is lower than pressure in chamber. Method of assembling and mounting of device is described in invention.

EFFECT: reduced possibility of failure of atomizer operating under pressure, low cost and ease of assembling and filling of device.
