Apparatus for dispensing metered quantities of liquefied gas such as liquid includes a thermally-insulated reservoir having at its bottom an outlet passage leading to a dispensing orifice outside the thermal insulator. There is a single valve for controlling admission of the liquefied gas to the dispensing orifice. The passage is in heat conductive relationship with a block of heat conductive material in the liquefied gas so as to maintain the passage sufficiently cold to prevent substantial evaporation of liquefied gas within the part of the passage wit...
Apparatus for dispensing a cryogenic liquid comprising a thermally insulated reservoir for containing said cryogenic liquid; a substantially solid block of heat conductive material disposed in said reservoir and having a passage therethrough with the diameter of said substantially solid block being at least three times greater than the diameter of said passage; a first end of said passage adapted to dispense said cryogenic liquid from said reservoir and a second end of said passage disposed at a location in the reservoir spaced away from the thermal insu...
