Abstract
The disclosure relates to a device for improving a vacuum in the housing of a machine, in particular a centrifugal-mass energy store, comprising a rotor, for example a shaft having a centrifugal mass arranged thereon, which rotor is supported on at least one superconducting bearing in a contactless manner and is arranged in a vacuum container. In order to maintain the operating state of the superconducting bearing, the superconducting bearing is thermally connected to a cold source cooled by a cryogenic medium. According to the invention, the vacuum in the vacuum container is improved by means of an adsorber thermally connected to a cooling apparatus. The cooling of the adsorber occurs preferably by means of evaporated cooling medium from the superconducting bearing.
