ABSTRACT:
A fluid operated multiple-disk friction clutch has a drive drum, a driven drum co-axial with the drive drum, a hydraulic piston provided in an oil chamber. The piston is moved by oil pressure to engage disks so as to engage the clutch. A pair of annular cam plates are provided to form an annular space adjacent the piston. One of the annular cam plates has a tapered surface. A plurality of fall weights are provided in the space. The tapered surface acts to provide an axial component from centrifugal force in the weights, so as to push the piston in the clutch disengagement direction.
