Swivel joint for one pipe and / or hose line and wall bushing for two pipes

摘要

The invention relates to a swivel joint (10, 122, 124) for pipe and / or hose lines (16, 106, 108) for transporting sterile fluids, comprising two joint parts (18, 20, 130, 132) having a fluid channel (22 ) and are rotatable with respect to each other about an axis of rotation (24), one in an annular gap (60) between the two joint parts (18, 20, 130, 132), against the two joint parts (18, 20, 130, 132) adjoining and in contact with the fluid located seal (62), and between the two hinge parts (18, 20; 130, 132) arranged to the rotation axis (24) coaxial rotary bearing (82). In order to more easily prevent the sterile fluids from being contaminated by lubricant or other impurities from the rotary bearing (82), it is proposed according to the invention that an open space (FIG. 94) is arranged.
