Arrangement with hermetically sealed separator as for magnetic couplings divides two spaces having different pressures or media and has surface structure to reduce eddy currents

摘要

An arrangement with a hermetically sealed separator (205) comprises inner and outer surfaces separating two spaces (209,210) having different pressures or media. The separator between magnetic components lies partly in both spaces and at least one surface has a structure (207,208) to reduce eddy currents.
