ABSTRACT:
A friction clutch has an apply piston slidably disposed in a clutch housing and cooperating therewith to form an apply chamber and a feed chamber. The effective area of the apply chamber is greater than the effective area of the feed chamber. Pressurized fluid for clutch engagement is distributed directly to the feed chamber and from there through a restricted passage to the apply chamber. Fluid pressure in the feed chamber is established by a variable regulator valve and operates on the effective area of the piston to urge disengagement of the clutch. Fluid pressure in the apply chamber is established by a pair of centrifugal exhaust control valves having individual speed-pressure relationships. The fluid pressure in the apply chamber acts on the effective area thereof and urges engagement of the clutch. The pressure level in the feed chamber controls the minimum speed of engagement which can be varied by varying the feed pressure. The clutch can be designed to engage at one speed and disengage at another speed by changing the feed pressure level after clutch engagement.
