ABSTRACT:
A refrigerator-operated apparatus having a housing adapted to accept components to be cooled. The housing is connected to a refrigerator housing via a connecting pipe, and the refrigerator includes a refrigerator generator extending through the housing and the connecting pipe, and encompassing at least one refrigerator stage that carries the components to be cooled. The apparatus further includes a damping mechanism for inhibiting vibrations generated by the refrigerator from being transmitted to the housing. The damping mechanism includes a separation space dividing the refrigerator housing into first and second connecting sections, and an elastic connecting ring connecting the first section to the second section. In one embodiment, the connecting ring extends across the separation space and is surrounded by a cover tube. In a second embodiment, the connecting ring is secured directly to one of the connecting sections, and is secured to the other connecting section via an adaptor pipe. Detent structure may be provided between the adaptor pipe and one of the connecting sections to cause the connecting ring to be pre-stressed.
