Granted: 1998-04-03
Abstract: Apparatus and method for using a compressed gas in an aerosol spray system to produce and maintain an effective aerosol spray includes the use of an aerosol spray valve 4 for emitting the aerosol spray. A dip tube 18 is coupled to the valve 4 and extends into the spray system. The tube 18 has an upper portion which is substantially airtight above an initial liquid level 14. A lower portion of the dip tube 18 extends below the initial liquid level 14 and has a liquid entrance hole 24 substantially at the bottom thereof. A vapor tap hole 26 is provided in the dip tube 18 above the liquid entrance hole 24 and below the initial liquid level 14.
