Abstract
An assembly for heat transfer between a rotating and a stationary body, characterized in that a certain number of annular elements (4) are arranged in the rotating part (1), concentric with its axis of rotation (2) and which extend in axial direction and which, with the rotation of the rotor, move in the spaces between a certain number of stationary annular elements (5), also concentric to the axis of rotation (2) and that are attached to a part (3) stationary with respect to the rotating part, producing heat transfer between both rotating (1) and stationary (3) parts.
