ABSTRACT OF THE DISCLOSURE A relatively rotatable coupling apparatus is dis- closed for conveying fluid from a stationary reservoir to a rotatable member. An adjustable throttle valve is operably connected intermediate of the coupling apparatus and the rotatable member for controlling the flow of fluid from the reservoir to the rotatable member. The relatively rotatable coupling apparatus has a first conduit portion connected to the reservoir defining an inlet flow path and a second conduit portion connected to the rotatable member defining a discharge flow path for the fluid. The first and second conduit portions are interconnected in an overlapping radially spaced apart relation by rotatable interconnecting means to define a relative motion gap between the over- lapping portions and to permit rotational movement of the second conduit portion relative to the first conduit por- tion. The throttle valve has a valve seat disposed in the discharge flow path of the second conduit portion and a valve plug disposed intermediate of the valve seat and the rotatable member. A stem connected to the valve plug extends through the first conduit portion and is mechanically linked with an adjustable piston for axially displacing the valve plug relative to the valve seat to provide adjustable throttl- ing of the flow of fluid from the reservoir to the rotatable member. -1-
