Abstract

The apparatus for providing a measured amount of a low boiling liquefied gas which can flow from an outlet of a thermally insulated container includes a fleece made of natural material, plastic material or metal connected with the outlet of the container, advantageously located immediately downstream of the outlet. This fleece provides a satisfactory separation of liquid and gas phases and thus a laminar liquefied gas flow and can assist in preventing freezing at the outlet due to moisture in the air. Advantageously a precise regulating valve which is sunk in the liquefied gas in the supply container provides continuous regulation of the liquefied gas flow.
