Abstract
An apparatus for controlling the pressure of a gas in a gas line includes a source of liquefied gas maintained at a prearranged gas pressure, an evaporation-inducing device connected to the source of liquefied gas and to the gas line, and a self-actuating valve disposed in the feed line for releasing a gas stream from the source of liquefied gas upon a predetermined pressure in the gas line falling below a prearranged pressure in the source of the liquefied gas, less a pressure loss in the feed line, so that the pressure in the gas line is substantially maintained at the predetermined pressure.
