DISPOSITIF DE REGLAGE DU NIVEAU D'UN GAZ LIQUEFIE

摘要

A control device for maintaining the level of a liquefied gas in a main container between two differenct limits, comprises a first vapor pressure bulb which is at the higher limit and a second vapor pressure bulb which is at the lower level, the bulbs containing a medium under pressure which condenses at the temperature of the liquefied gas. The medium pressures can actuate first and second control valves, which control flow of liquified gas from a storage container into said main container.
