Abstract
A friction clutch wherein the pressure plate is urged against the adjacent friction linings of the clutch disc by a diaphragm spring which reacts against a seat at the inner side of the clutch housing and bears against the pressure plate, at least when the clutch is engaged. The diaphragm spring is of one piece with or carries a resilient device which reacts against ramps at the exposed side of the housing and urges the diaphragm spring toward the seat. The ramps and the seat form part of a unit which automatically compensates for wear upon the friction linings of the clutch disc.
