Abstract
An arrangement for the transfer of electric current, a liquid medium and a gaseous medium between fixed and rotatable sections. A protective casing surrounds sliding brushes pressing against sliding surfaces. A passage for each medium is parallel with rotation and arranged at a boundary surface between the fixed and rotating sections. Passage transfer pipes in both sections communicate with the passages. A collector chamber arranged in the fixed section and an outlet pipe lead the gaseous medium out of the tubular rotating section. The arrangement for the transfer of a liquid medium is coaxially arranged inside the arrangement for the transfer of electric current. The protective casing provides a collector chamber for the gaseous medium.
