Method for operating a cryogenic refueling arrangement

Abstract

A method for operating a cryogenic refueling arrangement comprising a coupling device and a receiver socket, wherein the method comprises the following steps: a) coupling the coupling device to the receiver socket such that the coupling device and the receiver socket are locked to one another in a first position, b) applying a negative pressure to the coupling device and/or the receiver socket, c) unlocking the coupling device and the receiver socket so that the negative pressure causes the coupling device to move, in a direction toward the receiver socket, from the first position into a second position, which is different from the first position, d) locking the coupling device and the receiver socket in the second position, and e) starting a refueling process.
