ABSTRACT:
The invention is directed to an electrical liquid contact for an electrical machine such as an electric unipolar machine with a horizontal shaft. The liquid contact includes a ring gap which is sealed laterally by ring gaps which extend at an angle or radially and in which the metallic liquid present therein is set in rotation. This is accomplished by a circulating pump located outside the ring gap. In addition, the speed of rotation in the ring gap is matched to the pressure of the liquid by changing the cross-sectional area of the passage through which the liquid flows.
