ABSTRACT:
A clutch including: a first piston displaceable to operate a clutch pack; a second piston; a first fluid chamber partially formed by the pistons, wherein the second piston is displaceable by fluid pressure in the first fluid chamber; and a locking means fixable by the second piston to hold the pack closed. In a preferred embodiment, the locking means includes at least one displaceable ball. In another preferred embodiment, in response to a loss of fluid pressure in the first chamber, the second piston is displaceable to enable displacement of the locking means to open the pack. In a further preferred embodiment, the clutch includes a second chamber, separate from the first chamber and partially formed by the first piston. The first piston is displaceable in response to fluid pressure in the second chamber. The pack remains closed after a loss or reduction of fluid pressure in the second chamber.
