    Abstract: The lubrication system (150) includes a drive fluid valve member (156; 224) and a detune valve member (166; 260). The drive fluid valve member (156; 224) is movable from a first to a second position in response to drive fluid pressure to reduce the volume of a variable volume lubricant charge chamber (230). The detune valve member (166; 260) is movable from a first to a second position in response to lubricant pressure within the lubricant charge chamber (230), and is adapted to permit fluid communication between inlet and fluid bypass passages (146, 164) in its first position and to disengage the fluid connection in its second position.
