Abstract:
1. A multi-path rotary joint for flowable mediums, comprising: a first shell; and a second shell positioned at least partially within the first shell so that the longitudinal axis of the first shell is coincident with the longitudinal axis of the second shell, wherein the first shell is capable of rotating relative to the second shell about the coincident axis, wherein said first shell houses a first tubular structure extending from a first end of said first shell to a point between said first end and a second end of said first shell such that the first tubular structure does not extend beyond any end of the first shell, said second shell houses a second tubular structure extending from a first end of said second shell to a point between said first end and a second end of said second shell such that the second tubular structure does not extend beyond any end of the second shell, and said first tubular structure is mated with said second tubular structure to form a continuous flow path.
