ABSTRACT:
A multi-line or multi-path fluid swivel contains a plurality of stacked modules with each module having an internal core and an external housing. Each core includes one integral flow conduit which extends from the bottom of the core and opens through the side of the core into an annular chamber between the core and the housing. An opening in the housing permits flow of fluid out of or into the annular chamber. Seals between adjacent cores and seals between the cores and housing prevent or reduce leakage. The housings are rotatably mounted on the corresponding core with spaces between adjacent housings to permit axial core growth and deflection. Means between housings transmit rotational forces between housings and yet permit relative movement in the axial direction. Means are provided to fasten the adjacent cores to each other which act both as a dowel for transmitting rotational forces and as a bolt for locking cores together in the axial direction.
