摘要

The invention relates to a fluid rotary leadthrough having a journal and a sleeve. The sleeve and the journal are sealed off with respect to one another. The journal and the sleeve each have a line connection. The line connections, at least from time to time, are connected to one another via a fluid passage so that a flow of fluid through the fluid rotary leadthrough is made possible. The journal is arranged rotatably in the sleeve.
