Abstract:
1. A machine, comprising: a fixed part, the fixed part having a first and a second electrically insulated current transmission surface; a rotating part that rotates in relation to the fixed part, the rotating part having an assigned third and fourth current transmission surface for the first and second current transmission surface on the fixed part; a first and a second current transmission contact, wherein the third and fourth current transmission surfaces on the rotating part are electrically insulated from one another and form gaps with the associated first and second current transmission surface on the fixed part, the gaps containing liquid metal alloys to form the first and second current transmission contact; and a first electrical consumer fed by the first and second current transmission contact deployed on the rotating part; wherein the fixed part and the rotating part are arranged cylindrically about a cylinder axis, the rotating part enclosing the fixed part, the fixed and the rotating part each having a basic body in form of a hollow cylinder with a cylinder wall, wherein each cylinder wall includes an insulating ring to separate the cylinder wall into two parts insulated from one another, and wherein current supply systems are guided to the current transmission surfaces in the cylinder walls of the fixed and rotating parts, wherein a ring of U-shaped cross-section is provided on a cylinder wall of the rotating part for each current transmission surface, with the arms of the U-shape running parallel to the cylinder axis, and wherein a ring of L-shaped cross-section is provided on a cylinder wall of the fixed part for each current transmission surface, the first and second current transmission contact being formed by inserting a liquid metal alloy into the ring of U-shaped cross-section with one arm of the ring of L-shaped cross-section engaging in the U-shaped cross-section containing the liquid metal alloy, the engaging arm of the ring of L-shaped cross-section being sealed off from the two aims of the ring of U-shaped cross-section.
