ABSTRACT:
In the rotary coupling for feeding a gaseous or liquid pressurized medium from a first to a second machine part, which are rotatable with respect to each other, the first machine part contains at least one feed piston formed as a spring supported hollow piston and a sliding shoe is mounted between the feed piston and the second machine part. In order to make a rotary coupling, particularly a high pressure rotary coupling, in which when no operating medium is supplied during rotation no frictional forces are present between the component parts, the feed piston contains a mechanically driven check valve which opens in the feed direction and at least one piston spring braced between the feed piston and the first machine part is provided whose compression force is directed opposing that force which is exerted by the medium under pressure on the feed piston.
