  • Patent number: 6634178
    Abstract: In a prior-art method to regulate the pressure inside a cryogenic tank containing cold gas when a main stream for a consumer is withdrawn, heated gas in the form of a heating gas secondary stream, which is regulated as a function of the tank pressure, is fed through the cryogenic tank via a pipe. In order to start on this basis and to provide a simple and safe operating method to regulate the main stream and the secondary stream while also providing a cost-efficient device for this purpose, it is proposed by the method according to the invention that the secondary stream and the main stream be fed to a pressure-control means equipped with a first adjustable throttle for the secondary stream and with a second adjustable throttle for the main stream, whereby the throttles are coupled to each other in such a way that they can be opened and closed in opposite directions as a function of the pressure in the tank.
