Abstract
A process for withdrawing a gaseous and liquid cryogenic medium from a storage container is described, whereby the withdrawing from the gas phase or the liquid phase is carried out via at least one withdrawal line in each case, and these withdrawal lines are joined to at least one line that leads to the consumer of the cryogenic medium and can be switched using a valve between the two withdrawal lines. Further described is a storage container for a cryogenic medium with at least one withdrawal line, via which gaseous, cryogenic medium can be removed, and with at least one withdrawal line, via which liquid cryogenic medium can be removed, with a line, to which the withdrawal lines are joined and with at least one valve, which makes it possible to switch between the two withdrawal lines. According to the invention, valve (9) is moved using at least one electrochemical actuator (10), and the valve (9) and/or electrochemical actuator (10) can be arranged inside storage container (1).
