  • Dripping device for an absorption type refrigerator
    Patent number: 6263698
    Abstract: A liquid outlet pipe extended from a lower end of a liquid storage reservoir 420 is communicated with a section in the proximity of a lower portion of a refrigerant liquid dispersing pipe 421. A plurality of liquid outlet holes 426 are provided on an upper surface of the refrigerant liquid dispersing pipe 421. Diameters of the liquid outlet holes 426 are differently determined depending on a distance between a communicated section of the liquid dispersing pipe 421 and the liquid storage reservoir 420, in order to equalize an amount of refrigerant liquid flowing from the outlet holes 126. When the liquid storage reservoir 420 is filled with the refrigerant liquid, the refrigerant liquid flows upward within the liquid dispersing pipe 421 so as to inject the refrigerant liquid in accordance with a liquid head pressure.
