ABSTRACT:
A device for transferring fluid to a rotating unit (11), for example a cutting tool, having a housing (10) mounted on the rotating unit (11) and comprising an inner ring (21) and an outer ring (22). For purposes of decreasing the demand for close tolerance on fit between the inner ring (21) and the rotating unit (11) a connecting means (26) is adapted to non-rotatably attach the inner ring (21) to the rotating unit (11) and is provided with a through-flow passage (27) which interconnects passages (23, 24, 25) in the inner ring (21) and the outer ring (22) communicating with a fluid source with a passage (19) in the rotating unit (11).
