A ROTARY COUPLING

摘要

A liquid feed device for conducting a pressurized medium from a stationary housing to a rotatable component is so constructed that the applied force of a sealing surface of a sliding shoe of the housing on the running surface of the movable structural component is regulated so that on the one hand an effective seal between the sealing surface and the running surface independent of the operating conditions of the system is guaranteed and on the other hand the frictional forces operating are kept as small as possible.
