ABSTRACT:
A fluid operating clutch has an apply chamber and a centrifugal balance chamber. The balance chamber is disposed radially outward of the apply chamber. The area of the chambers is varied inversely with the effective radius such that the balance chamber has less area than the apply chamber. When the clutch is engaged, the balance chamber is filled prior to the apply chamber to prevent premature "drift on" of the clutch. The balance chamber does not effect normal operation of the clutch, but does continue to provide centrifugal balance throughout the operating range of the clutch.
