A rotary valve (100) including a stationary member (102) comprising an interfacial surface, and a rotatable member (104) attachable to a spindle (156) of a machine tool (150). The rotatable member (102) has an axis of rotation (130) and includes a rotatable surface in fluid communication with the interfacial surface of the stationary member (104), such that the working gas is conductible from the stationary member (102) to the rotatable member (104) via communication ports (122, 124) in the stationary member (102) and communication ports (134, 135) in the rotatable member (104) to actuate a portion of the machine tool (150), wherein the working gas flowing from the interfacial surface to the rotatable surface imparts a pressure therebetween, thereby creating a lubricating film therebetween. |
