Abstract
Abstract This invention relates to a floating manifold capable of transferring hydraulic fluid between a stationary member and a rotatable member. The floating manifold is comprised of a collar axially aligned onto a portion of the rotatable member, a passage means extending radially into the collar for the passage of a hydraulic fluid, and attachment means mounted on the outer periphery of said collar for permitting limited axial and rotational movement of the collar relative to the stationary member.
